Let's divide 57480947 by 521
Let's see how many times 521 fits into 57480947.

On to step 1:
The number 521 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 521

Step 2:
If we divide 57 by 521, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 521

Going ahead to step 3:
574 divided by 521 is 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 521 from 574 leaves us with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 521

On to step 4:
The number 521 fits into 538 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 521 from 538 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 521

Going ahead to step 5:
The number 521 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
The remainder is 170 after subtracting 0 from 170.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 521

Advancing to step 6:
The number 521 fits into 1709 3 times, leaving a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 1103.0
Deduct 1563 from 1709 and we're left with 146.
Append the next digit (4) from the dividend to 146 and continue with: 1464 / 521

Step 7:
When dividing 1464 by 521, we get 2 with a remainder of 422.
The number 2 becomes the next digit in our result. 
Result so far: 11032.0
If we take 1042 away from 1464, we end up with 422.
Take the next digit (7) from the dividend and append it to 422, then repeat: 4227 / 521

Going ahead to step 8:
521 can be fit into 4227 8 times, resulting in a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 110328.0
Deduct 4168 from 4227 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
The number 521 fits into 590 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 110328.1
If we take 521 away from 590, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
690 divided by 521 is 1 with a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 110328.11
If we take 521 away from 690, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Our division results in 110328.11 with a remaining 0.169.
