We look at the division of 75157957 by 339 
The aim is to understand the frequency of 339 in 75157957.

Let's proceed to step 1:
339 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 339

Going ahead to step 2:
339 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 339

Let's proceed to step 3:
339 can be fit into 751 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 678 from 751, we get 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 339

Step 4:
339 can be fit into 735 2 times, resulting in a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 678 from 735 to get 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 339

On to step 5:
339 goes into 577 1 times with a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 221.0
Subtract 339 from 577 to get 238.
Include the next digit (9) from the dividend after 238, then repeat: 2389 / 339

Advancing to step 6:
When dividing 2389 by 339, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 2217.0
The remainder is 16 after subtracting 2373 from 2389.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 339

Let's proceed to step 7:
If we divide 165 by 339, we get 0 and a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 22170.0
If we take 0 away from 165, we end up with 165.
Fetch the next digit (7) from the dividend, attach it to 165 and continue: 1657 / 339

Going ahead to step 8:
339 goes into 1657 4 times with a remainder of 301.
Write down 4 as next digit of the result. 
Result so far: 221704.0
If we take 1356 away from 1657, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
The number 339 fits into 3010 8 times, leaving a remainder of 298.
Put 8 as the next digit of the answer. 
Result so far: 221704.8
Subtract 2712 from 3010 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 10:
339 goes into 2980 8 times with a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 221704.88
Deduct 2712 from 2980 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The quotient of the division is 221704.88, and the remainder is 0.268.
