We divide 869280 by 66
We want to divide 869280 by 66.

Advancing to step 1:
The number 66 fits into 8 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 66

Moving on to step 2:
66 can be fit into 86 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 66 from 86 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 66

Advancing to step 3:
209 divided by 66 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 198 from 209 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 66

Going ahead to step 4:
The number 66 fits into 112 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Deduct 66 from 112 and we're left with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 66

Step 5:
66 can be fit into 468 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 1317.0
The remainder is 6 after subtracting 462 from 468.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 66

Advancing to step 6:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 13170.0
If we take 0 away from 60, we end up 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.

On to step 7:
600 divided by 66 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 13170.9
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 66, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 13170.9
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
66 can be fit into 600 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 13170.909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 13170.909
If we take 0 away from 60, we end up 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.

Let's proceed to step 11:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 13170.90909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 66, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 13170.90909
If we take 0 away from 60, we end up 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 13:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 13170.9090909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
66 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 13170.9090909
Subtract 0 from 60 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.

Our division results in 13170.9090909 with a remaining 6e-08.
