We're dividing 39437793 by 855 
The aim is to understand the frequency of 855 in 39437793.

Going ahead to step 1:
The number 855 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 855

Going ahead to step 2:
If we divide 39 by 855, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 855

Let's proceed to step 3:
When dividing 394 by 855, we get 0 with a remainder of 394.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Take the next digit (3) from the dividend and append it to 394, then repeat: 3943 / 855

Let's proceed to step 4:
855 goes into 3943 4 times with a remainder of 523.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3420 away from 3943, we end up with 523.
Bring next digit (7) of the dividend behind the 523 and repeat the process: 5237 / 855

Going ahead to step 5:
5237 divided by 855 is 6 with a remainder of 107.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 107 after subtracting 5130 from 5237.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 855

Advancing to step 6:
If we divide 1077 by 855, we get 1 and a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
If we take 855 away from 1077, we end up with 222.
Bring next digit (9) of the dividend behind the 222 and repeat the process: 2229 / 855

Going ahead to step 7:
855 goes into 2229 2 times with a remainder of 519.
Put 2 as the next digit of the answer. 
Result so far: 4612.0
If we subtract 1710 from 2229, we get 519.
Fetch the next digit (3) from the dividend, attach it to 519 and continue: 5193 / 855

Moving on to step 8:
855 can be fit into 5193 6 times, resulting in a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 46126.0
If we take 5130 away from 5193, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
The number 855 fits into 630 0 times, leaving a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 46126.0
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 10:
If we divide 6300 by 855, we get 7 and a remainder of 315.
The next digit of our result is 7. 
Result so far: 46126.07
The remainder is 315 after subtracting 5985 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 11:
The number 855 fits into 3150 3 times, leaving a remainder of 585.
Record the quotient 3 as the next digit in the result. 
Result so far: 46126.073
If we subtract 2565 from 3150, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 12:
The number 855 fits into 5850 6 times, leaving a remainder of 720.
Put 6 as the next digit of the answer. 
Result so far: 46126.0736
If we take 5130 away from 5850, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 13:
The number 855 fits into 7200 8 times, leaving a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 46126.07368
Deduct 6840 from 7200 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 14:
If we divide 3600 by 855, we get 4 and a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 46126.073684
If we subtract 3420 from 3600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
855 can be fit into 1800 2 times, resulting in a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 46126.0736842
The remainder is 90 after subtracting 1710 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
When dividing 900 by 855, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 46126.07368421
The remainder is 45 after subtracting 855 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 46126.07368421, and the remainder is 4.5e-08.
