Let's divide 142748 by 57
The aim is to understand the frequency of 57 in 142748.

Moving on to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 57

Going ahead to step 2:
When dividing 14 by 57, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 57

On to step 3:
The number 57 fits into 142 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 114 from 142 to get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 57

Going ahead to step 4:
If we divide 287 by 57, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 285 away from 287, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 57

Step 5:
57 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 57

Moving on to step 6:
When dividing 248 by 57, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 2504.0
Subtract 228 from 248 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
57 goes into 200 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 2504.3
Deduct 171 from 200 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2504.35
If we subtract 285 from 290, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 57, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 2504.35
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
57 can be fit into 500 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 2504.3508
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
440 divided by 57 is 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 2504.35087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
57 can be fit into 410 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2504.350877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 2504.350877, with a leftover of 1.1e-06.
