We look at the division of 42131 by 57 
We're looking to find how many times 57 goes into 42131.

Step 1:
4 divided by 57 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 57

Let's proceed to step 2:
42 divided by 57 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 57

Step 3:
57 goes into 421 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 22 after subtracting 399 from 421.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 57

Let's proceed to step 4:
When dividing 223 by 57, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 52 after subtracting 171 from 223.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 57

Going ahead to step 5:
57 can be fit into 521 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 739.0
Deduct 513 from 521 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 6:
57 can be fit into 80 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 739.1
Subtract 57 from 80 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
57 goes into 230 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 739.14
Subtract 228 from 230 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 57 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 739.14
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 57 fits into 200 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 739.1403
If we take 171 away from 200, we end up 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.

Step 10:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 739.14035
If we take 285 away from 290, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 57, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 739.14035
Subtracting 0 from 50 leaves us 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 12:
57 goes into 500 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 739.1403508
The remainder is 44 after subtracting 456 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
440 divided by 57 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 739.14035087
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 739.14035087 with a balance of 4.1e-08.
