521601 divided by 57 
We want to divide 521601 by 57.

Advancing to step 1:
The number 57 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 57

On to step 2:
When dividing 52 by 57, we get 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 57

Step 3:
When dividing 521 by 57, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 513 from 521 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 57

Let's proceed to step 4:
86 divided by 57 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 29 after subtracting 57 from 86.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 57

On to step 5:
When dividing 290 by 57, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 915.0
Subtract 285 from 290 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 57

On to step 6:
57 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 9150.0
Subtract 0 from 51 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
If we divide 510 by 57, we get 8 and a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 9150.8
Deduct 456 from 510 and we're left 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.

Moving on to step 8:
57 can be fit into 540 9 times, resulting in a remainder of 27.
The next digit of our result is 9. 
Result so far: 9150.89
Deduct 513 from 540 and we're left 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.

Moving on to step 9:
57 goes into 270 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 9150.894
Deduct 228 from 270 and we're left 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 10:
420 divided by 57 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 9150.8947
The remainder is 21 after subtracting 399 from 420.
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 11:
If we divide 210 by 57, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 9150.89473
If we subtract 171 from 210, we 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.

Let's proceed to step 12:
390 divided by 57 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 9150.894736
Subtract 342 from 390 to get 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 13:
57 can be fit into 480 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 9150.8947368
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.

Let's proceed to step 14:
When dividing 240 by 57, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 9150.89473684
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.

The final result is 9150.89473684 with a remainder of 1.2e-08.
