We're dividing 66899313 by 963 
Our goal is to divide 66899313 by 963.

Moving on to step 1:
963 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 963

Step 2:
963 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 963

Advancing to step 3:
When dividing 668 by 963, we get 0 with a remainder of 668.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 668 to get 668.
Include the next digit (9) from the dividend after 668, then repeat: 6689 / 963

Going ahead to step 4:
963 goes into 6689 6 times with a remainder of 911.
The next digit of our result is 6. 
Result so far: 6.0
If we take 5778 away from 6689, we end up with 911.
Include the next digit (9) from the dividend after 911, then repeat: 9119 / 963

Let's proceed to step 5:
963 goes into 9119 9 times with a remainder of 452.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtract 8667 from 9119 to get 452.
Bring next digit (3) of the dividend behind the 452 and repeat the process: 4523 / 963

Going ahead to step 6:
The number 963 fits into 4523 4 times, leaving a remainder of 671.
Use 4 as the next digit of our solution. 
Result so far: 694.0
The remainder is 671 after subtracting 3852 from 4523.
Bring next digit (1) of the dividend behind the 671 and repeat the process: 6711 / 963

Let's proceed to step 7:
The number 963 fits into 6711 6 times, leaving a remainder of 933.
The number 6 becomes the next digit in our result. 
Result so far: 6946.0
Subtracting 5778 from 6711 leaves us with 933.
Include the next digit (3) from the dividend after 933, then repeat: 9333 / 963

Advancing to step 8:
963 goes into 9333 9 times with a remainder of 666.
Put 9 as the next digit of the answer. 
Result so far: 69469.0
Deduct 8667 from 9333 and we're left with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Advancing to step 9:
963 can be fit into 6660 6 times, resulting in a remainder of 882.
Write down 6 as next digit of the result. 
Result so far: 69469.6
Subtract 5778 from 6660 to get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Moving on to step 10:
963 can be fit into 8820 9 times, resulting in a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 69469.69
Deduct 8667 from 8820 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 11:
963 goes into 1530 1 times with a remainder of 567.
Put 1 as the next digit of the answer. 
Result so far: 69469.691
If we take 963 away from 1530, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 12:
963 goes into 5670 5 times with a remainder of 855.
Record the quotient 5 as the next digit in the result. 
Result so far: 69469.6915
Subtract 4815 from 5670 to get 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

Moving on to step 13:
8550 divided by 963 is 8 with a remainder of 846.
Write down 8 as next digit of the result. 
Result so far: 69469.69158
Subtract 7704 from 8550 to get 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Advancing to step 14:
8460 divided by 963 is 8 with a remainder of 756.
Use 8 as the next digit of our solution. 
Result so far: 69469.691588
If we take 7704 away from 8460, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

The final outcome is 69469.691588, with a leftover of 7.56e-05.
