We're dividing 83397 by 57 
The aim is to understand the frequency of 57 in 83397.

Moving on to step 1:
The number 57 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 57

Step 2:
57 can be fit into 83 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 57 from 83, we get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 57

Step 3:
263 divided by 57 is 4 with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 228 from 263 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 57

On to step 4:
The number 57 fits into 359 6 times, leaving a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
The remainder is 17 after subtracting 342 from 359.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 57

Going ahead to step 5:
If we divide 177 by 57, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1463.0
If we subtract 171 from 177, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
If we divide 60 by 57, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1463.1
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 57, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1463.1
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
57 goes into 300 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1463.105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1463.1052
Subtract 114 from 150 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
360 divided by 57 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 1463.10526
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 57, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 1463.105263
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 57, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1463.1052631
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
When dividing 330 by 57, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1463.10526315
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 1463.10526315 and a remainder of 4.5e-08.
