Let's divide 57771020 by 660
Our goal is to divide 57771020 by 660.

On to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 660

On to step 2:
660 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 660

Step 3:
660 goes into 577 0 times with a remainder of 577.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 577, we get 577.
Grab the next digit (7) from the dividend, add it to 577, then carry on: 5777 / 660

Advancing to step 4:
If we divide 5777 by 660, we get 8 and a remainder of 497.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 5280 away from 5777, we end up with 497.
Fetch the next digit (1) from the dividend, attach it to 497 and continue: 4971 / 660

Let's proceed to step 5:
660 can be fit into 4971 7 times, resulting in a remainder of 351.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 4620 from 4971 to get 351.
Bring next digit (0) of the dividend behind the 351 and repeat the process: 3510 / 660

Advancing to step 6:
660 goes into 3510 5 times with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 875.0
Subtract 3300 from 3510 to get 210.
Append the next digit (2) from the dividend to 210 and continue with: 2102 / 660

Let's proceed to step 7:
If we divide 2102 by 660, we get 3 and a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 8753.0
Subtracting 1980 from 2102 leaves us with 122.
Include the next digit (0) from the dividend after 122, then repeat: 1220 / 660

On to step 8:
The number 660 fits into 1220 1 times, leaving a remainder of 560.
Use 1 as the next digit of our solution. 
Result so far: 87531.0
The remainder is 560 after subtracting 660 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 9:
When dividing 5600 by 660, we get 8 with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 87531.8
Deduct 5280 from 5600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
3200 divided by 660 is 4 with a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 87531.84
Deduct 2640 from 3200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
The number 660 fits into 5600 8 times, leaving a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 87531.848
If we subtract 5280 from 5600, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
When dividing 3200 by 660, we get 4 with a remainder of 560.
Use 4 as the next digit of our solution. 
Result so far: 87531.8484
The remainder is 560 after subtracting 2640 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
If we divide 5600 by 660, we get 8 and a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 87531.84848
If we take 5280 away from 5600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
When dividing 3200 by 660, we get 4 with a remainder of 560.
The next digit of our result is 4. 
Result so far: 87531.848484
Deduct 2640 from 3200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 15:
The number 660 fits into 5600 8 times, leaving a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 87531.8484848
If we take 5280 away from 5600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 16:
If we divide 3200 by 660, we get 4 and a remainder of 560.
The next digit of our result is 4. 
Result so far: 87531.84848484
Subtract 2640 from 3200 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 87531.84848484 and a remainder of 5.6e-07.
