We look at the division of 877968 by 66 
We're looking to find how many times 66 goes into 877968.

Going ahead to step 1:
8 divided by 66 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 66

Let's proceed to step 2:
If we divide 87 by 66, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 21 after subtracting 66 from 87.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 66

Going ahead to step 3:
The number 66 fits into 217 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 198 from 217 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 66

On to step 4:
When dividing 199 by 66, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we subtract 198 from 199, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 66

Let's proceed to step 5:
When dividing 16 by 66, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1330.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 66

Moving on to step 6:
If we divide 168 by 66, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 13302.0
The remainder is 36 after subtracting 132 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
When dividing 360 by 66, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 13302.5
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
66 goes into 300 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 13302.54
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13302.545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 66, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 13302.5454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 66, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 13302.54545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
300 divided by 66 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13302.545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 66, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 13302.5454545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 13302.54545454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 13302.54545454 and a remainder of 3.6e-08.
