We look at the division of 65419478 by 107 
The aim is to understand the frequency of 107 in 65419478.

On to step 1:
107 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 107

Advancing to step 2:
The number 107 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 107

Going ahead to step 3:
When dividing 654 by 107, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 642 from 654 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 107

Moving on to step 4:
The number 107 fits into 121 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 61.0
Deduct 107 from 121 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 107

Moving on to step 5:
149 divided by 107 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 611.0
The remainder is 42 after subtracting 107 from 149.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 107

Step 6:
424 divided by 107 is 3 with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 6113.0
If we subtract 321 from 424, we get 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 107

Let's proceed to step 7:
107 goes into 1037 9 times with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 61139.0
Deduct 963 from 1037 and we're left with 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 107

Advancing to step 8:
748 divided by 107 is 6 with a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 611396.0
The remainder is 106 after subtracting 642 from 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
107 goes into 1060 9 times with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 611396.9
Deduct 963 from 1060 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 10:
107 can be fit into 970 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 611396.99
Subtracting 963 from 970 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 611396.99 and a remainder of 0.007.
