8397486 divided by 107 
The aim is to understand the frequency of 107 in 8397486.

Moving on to step 1:
8 divided by 107 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 107

Step 2:
107 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 107

On to step 3:
The number 107 fits into 839 7 times, leaving a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 749 from 839 to get 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 107

Let's proceed to step 4:
If we divide 907 by 107, we get 8 and a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 856 from 907 and we're left with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 107

Let's proceed to step 5:
514 divided by 107 is 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 784.0
Subtract 428 from 514 to get 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 107

On to step 6:
If we divide 868 by 107, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7848.0
The remainder is 12 after subtracting 856 from 868.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 107

Step 7:
If we divide 126 by 107, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 78481.0
If we subtract 107 from 126, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
If we divide 190 by 107, we get 1 and a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 78481.1
If we subtract 107 from 190, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
If we divide 830 by 107, we get 7 and a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 78481.17
Subtract 749 from 830 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 10:
When dividing 810 by 107, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 78481.177
If we subtract 749 from 810, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 78481.177 with a remaining 0.0061.
