We look at the division of 42179 by 57 
We're looking to find how many times 57 goes into 42179.

Advancing to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 57

Step 2:
When dividing 42 by 57, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 57

Moving on to step 3:
The number 57 fits into 421 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 399 from 421 leaves us with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 57

Going ahead to step 4:
When dividing 227 by 57, we get 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtracting 171 from 227 leaves us with 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 57

Going ahead to step 5:
The number 57 fits into 569 9 times, leaving a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 739.0
If we take 513 away from 569, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 6:
If we divide 560 by 57, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 739.9
If we take 513 away from 560, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
The number 57 fits into 470 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 739.98
If we subtract 456 from 470, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
57 goes into 140 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 739.982
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 57, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 739.9824
If we subtract 228 from 260, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 57, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 739.98245
If we subtract 285 from 320, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
350 divided by 57 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 739.982456
If we subtract 342 from 350, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 57 fits into 80 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 739.9824561
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.

Going ahead to step 13:
When dividing 230 by 57, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 739.98245614
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.

In conclusion, the division gives 739.98245614 with a balance of 2e-09.
