We're dividing 57479571 by 660 
Let's see how many times 660 fits into 57479571.

Moving on to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 660

Moving on to step 2:
If we divide 57 by 660, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 660

Advancing to step 3:
660 can be fit into 574 0 times, resulting in a remainder of 574.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 574 leaves us with 574.
Take the next digit (7) from the dividend and append it to 574, then repeat: 5747 / 660

On to step 4:
When dividing 5747 by 660, we get 8 with a remainder of 467.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5280 from 5747 leaves us with 467.
Grab the next digit (9) from the dividend, add it to 467, then carry on: 4679 / 660

Step 5:
660 goes into 4679 7 times with a remainder of 59.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 4620 from 4679 to get 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 660

Advancing to step 6:
595 divided by 660 is 0 with a remainder of 595.
Put 0 as the next digit of the answer. 
Result so far: 870.0
If we take 0 away from 595, we end up with 595.
Fetch the next digit (7) from the dividend, attach it to 595 and continue: 5957 / 660

Advancing to step 7:
660 goes into 5957 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 8709.0
Deduct 5940 from 5957 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 660

Going ahead to step 8:
660 can be fit into 171 0 times, resulting in a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 87090.0
If we take 0 away from 171, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
The number 660 fits into 1710 2 times, leaving a remainder of 390.
The number 2 becomes the next digit in our result. 
Result so far: 87090.2
Subtract 1320 from 1710 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
660 can be fit into 3900 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 87090.25
If we subtract 3300 from 3900, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
660 can be fit into 6000 9 times, resulting in a remainder of 60.
The next digit of our result is 9. 
Result so far: 87090.259
Subtracting 5940 from 6000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
660 can be fit into 600 0 times, resulting in a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 87090.259
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 13:
The number 660 fits into 6000 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 87090.25909
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
When dividing 600 by 660, we get 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 87090.25909
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 15:
6000 divided by 660 is 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 87090.2590909
If we subtract 5940 from 6000, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
The number 660 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 87090.2590909
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 87090.2590909 and a remainder of 6e-07.
