7917 ÷ 57 
We're looking to find how many times 57 goes into 7917.

Advancing to step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 57

Moving on to step 2:
When dividing 79 by 57, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 57 away from 79, we end up with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 57

Advancing to step 3:
221 divided by 57 is 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 171 away from 221, we end up with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 57

Let's proceed to step 4:
The number 57 fits into 507 8 times, leaving a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 138.0
The remainder is 51 after subtracting 456 from 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 5:
57 can be fit into 510 8 times, resulting in a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 138.8
If we take 456 away from 510, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 6:
57 goes into 540 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 138.89
Subtracting 513 from 540 leaves us with 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 7:
57 can be fit into 270 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 138.894
If we take 228 away from 270, we end up 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.

Moving on to step 8:
If we divide 420 by 57, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 138.8947
Deduct 399 from 420 and we're left 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.

On to step 9:
If we divide 210 by 57, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 138.89473
Subtract 171 from 210 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 57 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 138.894736
Deduct 342 from 390 and we're left 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.

Step 11:
57 goes into 480 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 138.8947368
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
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: 138.89473684
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 138.89473684 with a balance of 1.2e-08.
