57870 divided by 66 
We're looking to find how many times 66 goes into 57870.

On to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 66

Moving on to step 2:
66 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 66

Let's proceed to step 3:
578 divided by 66 is 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 50 after subtracting 528 from 578.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 66

Moving on to step 4:
66 goes into 507 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 462 from 507, we get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 66

Moving on to step 5:
66 can be fit into 450 6 times, resulting in a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 876.0
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 6:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 876.8
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 876.81
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 876.818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 876.8181
The remainder is 54 after subtracting 66 from 120.
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 10:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 876.81818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 876.818181
Subtracting 66 from 120 leaves us 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.

Let's proceed to step 12:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 876.8181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
When dividing 120 by 66, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 876.81818181
If we take 66 away from 120, 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.

The final result is 876.81818181 with a remainder of 5.4e-08.
