Let's divide 239613 by 57
The aim is to understand the frequency of 57 in 239613.

Advancing to step 1:
57 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 57

Step 2:
23 divided by 57 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 57

Step 3:
239 divided by 57 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 228 from 239 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 57

Let's proceed to step 4:
57 goes into 116 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 114 away from 116, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 57

Going ahead to step 5:
The number 57 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 420.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 57

Moving on to step 6:
If we divide 213 by 57, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 4203.0
Subtracting 171 from 213 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
If we divide 420 by 57, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 4203.7
Subtracting 399 from 420 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
When dividing 210 by 57, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 4203.73
Subtracting 171 from 210 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
390 divided by 57 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 4203.736
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
57 can be fit into 480 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4203.7368
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
57 can be fit into 240 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4203.73684
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
When dividing 120 by 57, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4203.736842
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
When dividing 60 by 57, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 4203.7368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
57 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4203.7368421
Deduct 0 from 30 and we're left 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.

Our division results in 4203.7368421 with a remaining 3e-08.
