We're dividing 798466 by 90 
Our goal is to divide 798466 by 90.

Going ahead to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 90

Advancing to step 2:
90 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 90

Let's proceed to step 3:
If we divide 798 by 90, we get 8 and a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 720 away from 798, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 90

On to step 4:
The number 90 fits into 784 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 64 after subtracting 720 from 784.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 90

Advancing to step 5:
646 divided by 90 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 887.0
If we subtract 630 from 646, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 90

Moving on to step 6:
The number 90 fits into 166 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 8871.0
If we subtract 90 from 166, we 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.

Going ahead to step 7:
When dividing 760 by 90, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8871.8
If we take 720 away from 760, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 8871.84
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 8871.844
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 8871.844, with a leftover of 0.004.
