315657 divided by 66 
Let's see how many times 66 fits into 315657.

On to step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 66

Moving on to step 2:
If we divide 31 by 66, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 66

On to step 3:
The number 66 fits into 315 4 times, leaving a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 264 away from 315, we end up with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 66

Advancing to step 4:
The number 66 fits into 516 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 462 away from 516, we end up with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 66

On to step 5:
The number 66 fits into 545 8 times, leaving a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 478.0
If we take 528 away from 545, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 66

On to step 6:
When dividing 177 by 66, we get 2 with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 4782.0
Subtracting 132 from 177 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
When dividing 450 by 66, we get 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 4782.6
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.

Step 8:
The number 66 fits into 540 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 4782.68
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.

Moving on to step 9:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 4782.681
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.

Step 10:
The number 66 fits into 540 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 4782.6818
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 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: 4782.68181
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:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4782.681818
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.

Step 13:
66 goes into 120 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 4782.6818181
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.

On to step 14:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 4782.68181818
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.

The final result is 4782.68181818 with a remainder of 1.2e-08.
