231588 ÷ 57 
The aim is to understand the frequency of 57 in 231588.

Advancing to step 1:
If we divide 2 by 57, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 57

Step 2:
57 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 57

On to step 3:
57 can be fit into 231 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 228 from 231 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 57

Let's proceed to step 4:
57 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 57

On to step 5:
57 goes into 358 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 406.0
The remainder is 16 after subtracting 342 from 358.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 57

Advancing to step 6:
168 divided by 57 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 4062.0
The remainder is 54 after subtracting 114 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
If we divide 540 by 57, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 4062.9
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4062.94
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
57 goes into 420 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 4062.947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
When dividing 210 by 57, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 4062.9473
If we take 171 away from 210, we end up 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.

Going ahead to step 11:
If we divide 390 by 57, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 4062.94736
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.

Advancing to step 12:
57 goes into 480 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4062.947368
If we subtract 456 from 480, we 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.

Going ahead to step 13:
57 can be fit into 240 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4062.9473684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 57 fits into 120 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 4062.94736842
Deduct 114 from 120 and we're left 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.

The final outcome is 4062.94736842, with a leftover of 6e-09.
