798826 divided by 90 
We want to figure out the number of times 798826 can be divided by 90.

Going ahead to step 1:
7 divided by 90 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 90

Moving on to step 2:
79 divided by 90 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 90

On to step 3:
90 goes into 798 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 78 after subtracting 720 from 798.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 90

Moving on to step 4:
If we divide 788 by 90, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 88.0
If we subtract 720 from 788, we get 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 90

Step 5:
The number 90 fits into 682 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 887.0
Subtract 630 from 682 to get 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 90

Advancing to step 6:
When dividing 526 by 90, we get 5 with a remainder of 76.
Write down 5 as next digit of the result. 
Result so far: 8875.0
Subtract 450 from 526 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
If we divide 760 by 90, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8875.8
If we subtract 720 from 760, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8875.84
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8875.844
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 8875.844, with a leftover of 0.004.
