We're dividing 8091640 by 826 
We want to figure out the number of times 8091640 can be divided by 826.

Moving on to step 1:
When dividing 8 by 826, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 826

Moving on to step 2:
80 divided by 826 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 826

Moving on to step 3:
826 can be fit into 809 0 times, resulting in a remainder of 809.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Fetch the next digit (1) from the dividend, attach it to 809 and continue: 8091 / 826

Advancing to step 4:
826 can be fit into 8091 9 times, resulting in a remainder of 657.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7434 from 8091 leaves us with 657.
Bring next digit (6) of the dividend behind the 657 and repeat the process: 6576 / 826

Step 5:
826 can be fit into 6576 7 times, resulting in a remainder of 794.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 5782 away from 6576, we end up with 794.
Fetch the next digit (4) from the dividend, attach it to 794 and continue: 7944 / 826

On to step 6:
7944 divided by 826 is 9 with a remainder of 510.
Write down 9 as next digit of the result. 
Result so far: 979.0
The remainder is 510 after subtracting 7434 from 7944.
Grab the next digit (0) from the dividend, add it to 510, then carry on: 5100 / 826

Moving on to step 7:
826 can be fit into 5100 6 times, resulting in a remainder of 144.
The next digit of our result is 6. 
Result so far: 9796.0
Subtracting 4956 from 5100 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 8:
1440 divided by 826 is 1 with a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 9796.1
Subtract 826 from 1440 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 9:
The number 826 fits into 6140 7 times, leaving a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 9796.17
The remainder is 358 after subtracting 5782 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 10:
When dividing 3580 by 826, we get 4 with a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 9796.174
Deduct 3304 from 3580 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
2760 divided by 826 is 3 with a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 9796.1743
If we subtract 2478 from 2760, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 12:
2820 divided by 826 is 3 with a remainder of 342.
Record the quotient 3 as the next digit in the result. 
Result so far: 9796.17433
Deduct 2478 from 2820 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 9796.17433, with a leftover of 0.000342.
