We look at the division of 64211699 by 939 
The aim is to understand the frequency of 939 in 64211699.

On to step 1:
939 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 939

Let's proceed to step 2:
939 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 939

Let's proceed to step 3:
642 divided by 939 is 0 with a remainder of 642.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Grab the next digit (1) from the dividend, add it to 642, then carry on: 6421 / 939

Moving on to step 4:
939 can be fit into 6421 6 times, resulting in a remainder of 787.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 787 after subtracting 5634 from 6421.
Bring next digit (1) of the dividend behind the 787 and repeat the process: 7871 / 939

Step 5:
7871 divided by 939 is 8 with a remainder of 359.
The next digit of our result is 8. 
Result so far: 68.0
Subtract 7512 from 7871 to get 359.
Bring next digit (6) of the dividend behind the 359 and repeat the process: 3596 / 939

Moving on to step 6:
3596 divided by 939 is 3 with a remainder of 779.
Put 3 as the next digit of the answer. 
Result so far: 683.0
If we subtract 2817 from 3596, we get 779.
Fetch the next digit (9) from the dividend, attach it to 779 and continue: 7799 / 939

Advancing to step 7:
When dividing 7799 by 939, we get 8 with a remainder of 287.
The next digit of our result is 8. 
Result so far: 6838.0
Deduct 7512 from 7799 and we're left with 287.
Fetch the next digit (9) from the dividend, attach it to 287 and continue: 2879 / 939

Let's proceed to step 8:
If we divide 2879 by 939, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 68383.0
If we subtract 2817 from 2879, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
The number 939 fits into 620 0 times, leaving a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 68383.0
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
939 goes into 6200 6 times with a remainder of 566.
Record the quotient 6 as the next digit in the result. 
Result so far: 68383.06
If we take 5634 away from 6200, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 11:
939 goes into 5660 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 68383.066
Deduct 5634 from 5660 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 68383.066 with a remaining 0.0026.
