39307866 ÷ 803 
The aim is to understand the frequency of 803 in 39307866.

Let's proceed to step 1:
803 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 803

On to step 2:
803 can be fit into 39 0 times, resulting in 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.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 803

Advancing to step 3:
When dividing 393 by 803, we get 0 with a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Take the next digit (0) from the dividend and append it to 393, then repeat: 3930 / 803

Moving on to step 4:
If we divide 3930 by 803, we get 4 and a remainder of 718.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3212 from 3930 and we're left with 718.
Take the next digit (7) from the dividend and append it to 718, then repeat: 7187 / 803

Step 5:
803 goes into 7187 8 times with a remainder of 763.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 6424 from 7187, we get 763.
Include the next digit (8) from the dividend after 763, then repeat: 7638 / 803

Going ahead to step 6:
7638 divided by 803 is 9 with a remainder of 411.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
If we subtract 7227 from 7638, we get 411.
Bring next digit (6) of the dividend behind the 411 and repeat the process: 4116 / 803

Let's proceed to step 7:
803 can be fit into 4116 5 times, resulting in a remainder of 101.
Record the quotient 5 as the next digit in the result. 
Result so far: 4895.0
Subtract 4015 from 4116 to get 101.
Append the next digit (6) from the dividend to 101 and continue with: 1016 / 803

Advancing to step 8:
When dividing 1016 by 803, we get 1 with a remainder of 213.
The next digit of our result is 1. 
Result so far: 48951.0
If we take 803 away from 1016, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 9:
2130 divided by 803 is 2 with a remainder of 524.
Record the quotient 2 as the next digit in the result. 
Result so far: 48951.2
Subtract 1606 from 2130 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 10:
803 goes into 5240 6 times with a remainder of 422.
Put 6 as the next digit of the answer. 
Result so far: 48951.26
If we take 4818 away from 5240, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 11:
4220 divided by 803 is 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 48951.265
Subtracting 4015 from 4220 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 12:
803 goes into 2050 2 times with a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 48951.2652
If we take 1606 away from 2050, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 13:
If we divide 4440 by 803, we get 5 and a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 48951.26525
Subtracting 4015 from 4440 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 14:
803 goes into 4250 5 times with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 48951.265255
Subtracting 4015 from 4250 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 48951.265255 with a remainder of 2.35e-05.
