80961621 ÷ 826 
We want to divide 80961621 by 826.

On to step 1:
The number 826 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 826

Step 2:
When dividing 80 by 826, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 826

Moving on to step 3:
When dividing 809 by 826, we get 0 with a remainder of 809.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 809 to get 809.
Take the next digit (6) from the dividend and append it to 809, then repeat: 8096 / 826

Advancing to step 4:
8096 divided by 826 is 9 with a remainder of 662.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7434 from 8096 to get 662.
Bring next digit (1) of the dividend behind the 662 and repeat the process: 6621 / 826

Let's proceed to step 5:
6621 divided by 826 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 98.0
If we take 6608 away from 6621, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 826

Let's proceed to step 6:
136 divided by 826 is 0 with a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 980.0
The remainder is 136 after subtracting 0 from 136.
Bring next digit (2) of the dividend behind the 136 and repeat the process: 1362 / 826

Advancing to step 7:
1362 divided by 826 is 1 with a remainder of 536.
Put 1 as the next digit of the answer. 
Result so far: 9801.0
Subtracting 826 from 1362 leaves us with 536.
Append the next digit (1) from the dividend to 536 and continue with: 5361 / 826

On to step 8:
When dividing 5361 by 826, we get 6 with a remainder of 405.
The number 6 becomes the next digit in our result. 
Result so far: 98016.0
Deduct 4956 from 5361 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 9:
The number 826 fits into 4050 4 times, leaving a remainder of 746.
Record the quotient 4 as the next digit in the result. 
Result so far: 98016.4
Deduct 3304 from 4050 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Advancing to step 10:
7460 divided by 826 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 98016.49
Subtract 7434 from 7460 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
826 goes into 260 0 times with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 98016.49
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
If we divide 2600 by 826, we get 3 and a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 98016.4903
If we take 2478 away from 2600, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 13:
826 goes into 1220 1 times with a remainder of 394.
Write down 1 as next digit of the result. 
Result so far: 98016.49031
Subtracting 826 from 1220 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 14:
826 goes into 3940 4 times with a remainder of 636.
The next digit of our result is 4. 
Result so far: 98016.490314
The remainder is 636 after subtracting 3304 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 15:
826 goes into 6360 7 times with a remainder of 578.
The next digit of our result is 7. 
Result so far: 98016.4903147
Subtracting 5782 from 6360 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 16:
5780 divided by 826 is 6 with a remainder of 824.
The next digit of our result is 6. 
Result so far: 98016.49031476
The remainder is 824 after subtracting 4956 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

The final result is 98016.49031476 with a remainder of 8.24e-07.
