We look at the division of 66511063 by 988 
Our goal is to divide 66511063 by 988.

Going ahead to step 1:
6 divided by 988 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 988

On to step 2:
988 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 988

On to step 3:
988 can be fit into 665 0 times, resulting in a remainder of 665.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 665 to get 665.
Grab the next digit (1) from the dividend, add it to 665, then carry on: 6651 / 988

Advancing to step 4:
If we divide 6651 by 988, we get 6 and a remainder of 723.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5928 from 6651 leaves us with 723.
Bring next digit (1) of the dividend behind the 723 and repeat the process: 7231 / 988

Step 5:
988 can be fit into 7231 7 times, resulting in a remainder of 315.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 6916 from 7231, we get 315.
Grab the next digit (0) from the dividend, add it to 315, then carry on: 3150 / 988

Advancing to step 6:
When dividing 3150 by 988, we get 3 with a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 673.0
Subtract 2964 from 3150 to get 186.
Grab the next digit (6) from the dividend, add it to 186, then carry on: 1866 / 988

Advancing to step 7:
The number 988 fits into 1866 1 times, leaving a remainder of 878.
Record the quotient 1 as the next digit in the result. 
Result so far: 6731.0
Subtracting 988 from 1866 leaves us with 878.
Take the next digit (3) from the dividend and append it to 878, then repeat: 8783 / 988

Moving on to step 8:
988 goes into 8783 8 times with a remainder of 879.
Write down 8 as next digit of the result. 
Result so far: 67318.0
Subtract 7904 from 8783 to get 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

On to step 9:
8790 divided by 988 is 8 with a remainder of 886.
Record the quotient 8 as the next digit in the result. 
Result so far: 67318.8
If we subtract 7904 from 8790, we get 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Advancing to step 10:
The number 988 fits into 8860 8 times, leaving a remainder of 956.
Use 8 as the next digit of our solution. 
Result so far: 67318.88
Subtract 7904 from 8860 to get 956.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9560, and continue the process.

The quotient of the division is 67318.88, and the remainder is 0.956.
