We look at the division of 37403049 by 865 
The aim is to understand the frequency of 865 in 37403049.

Let's proceed to step 1:
865 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 865

Going ahead to step 2:
If we divide 37 by 865, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 865

Let's proceed to step 3:
If we divide 374 by 865, we get 0 and a remainder of 374.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 374 to get 374.
Fetch the next digit (0) from the dividend, attach it to 374 and continue: 3740 / 865

Going ahead to step 4:
The number 865 fits into 3740 4 times, leaving a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3460 from 3740 and we're left with 280.
Bring next digit (3) of the dividend behind the 280 and repeat the process: 2803 / 865

Let's proceed to step 5:
865 can be fit into 2803 3 times, resulting in a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 208 after subtracting 2595 from 2803.
Take the next digit (0) from the dividend and append it to 208, then repeat: 2080 / 865

Advancing to step 6:
865 can be fit into 2080 2 times, resulting in a remainder of 350.
Record the quotient 2 as the next digit in the result. 
Result so far: 432.0
Subtracting 1730 from 2080 leaves us with 350.
Bring next digit (4) of the dividend behind the 350 and repeat the process: 3504 / 865

Going ahead to step 7:
If we divide 3504 by 865, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 4324.0
Subtracting 3460 from 3504 leaves us with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 865

Step 8:
If we divide 449 by 865, we get 0 and a remainder of 449.
Write down 0 as next digit of the result. 
Result so far: 43240.0
Subtracting 0 from 449 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 9:
The number 865 fits into 4490 5 times, leaving a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 43240.5
The remainder is 165 after subtracting 4325 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
1650 divided by 865 is 1 with a remainder of 785.
Put 1 as the next digit of the answer. 
Result so far: 43240.51
If we take 865 away from 1650, we end up with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

On to step 11:
865 goes into 7850 9 times with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 43240.519
The remainder is 65 after subtracting 7785 from 7850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
650 divided by 865 is 0 with a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 43240.519
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 13:
865 can be fit into 6500 7 times, resulting in a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 43240.51907
If we subtract 6055 from 6500, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 14:
The number 865 fits into 4450 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 43240.519075
If we take 4325 away from 4450, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
The number 865 fits into 1250 1 times, leaving a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 43240.5190751
Subtracting 865 from 1250 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 16:
If we divide 3850 by 865, we get 4 and a remainder of 390.
The next digit of our result is 4. 
Result so far: 43240.51907514
If we take 3460 away from 3850, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 43240.51907514 with a remainder of 3.9e-07.
