68856609 divided by 991 
Our goal is to divide 68856609 by 991.

Step 1:
If we divide 6 by 991, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 991

Moving on to step 2:
991 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 991

Advancing to step 3:
991 can be fit into 688 0 times, resulting in a remainder of 688.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 688, we end up with 688.
Fetch the next digit (5) from the dividend, attach it to 688 and continue: 6885 / 991

Let's proceed to step 4:
The number 991 fits into 6885 6 times, leaving a remainder of 939.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 5946 from 6885 and we're left with 939.
Fetch the next digit (6) from the dividend, attach it to 939 and continue: 9396 / 991

Going ahead to step 5:
If we divide 9396 by 991, we get 9 and a remainder of 477.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 8919 away from 9396, we end up with 477.
Append the next digit (6) from the dividend to 477 and continue with: 4776 / 991

On to step 6:
When dividing 4776 by 991, we get 4 with a remainder of 812.
The next digit of our result is 4. 
Result so far: 694.0
If we subtract 3964 from 4776, we get 812.
Include the next digit (0) from the dividend after 812, then repeat: 8120 / 991

Step 7:
991 goes into 8120 8 times with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 6948.0
The remainder is 192 after subtracting 7928 from 8120.
Grab the next digit (9) from the dividend, add it to 192, then carry on: 1929 / 991

Moving on to step 8:
The number 991 fits into 1929 1 times, leaving a remainder of 938.
Record the quotient 1 as the next digit in the result. 
Result so far: 69481.0
Subtracting 991 from 1929 leaves us with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

On to step 9:
9380 divided by 991 is 9 with a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 69481.9
If we take 8919 away from 9380, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 10:
991 can be fit into 4610 4 times, resulting in a remainder of 646.
The next digit of our result is 4. 
Result so far: 69481.94
Subtract 3964 from 4610 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 11:
If we divide 6460 by 991, we get 6 and a remainder of 514.
The number 6 becomes the next digit in our result. 
Result so far: 69481.946
If we take 5946 away from 6460, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 12:
991 can be fit into 5140 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 69481.9465
Subtracting 4955 from 5140 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 13:
The number 991 fits into 1850 1 times, leaving a remainder of 859.
The number 1 becomes the next digit in our result. 
Result so far: 69481.94651
If we take 991 away from 1850, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Moving on to step 14:
When dividing 8590 by 991, we get 8 with a remainder of 662.
Use 8 as the next digit of our solution. 
Result so far: 69481.946518
The remainder is 662 after subtracting 7928 from 8590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

On to step 15:
6620 divided by 991 is 6 with a remainder of 674.
The next digit of our result is 6. 
Result so far: 69481.9465186
Subtract 5946 from 6620 to get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Advancing to step 16:
The number 991 fits into 6740 6 times, leaving a remainder of 794.
The number 6 becomes the next digit in our result. 
Result so far: 69481.94651866
If we take 5946 away from 6740, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

After the division, we end up with 69481.94651866 and a remainder of 7.94e-07.
