We're dividing 891202 by 90 
We want to divide 891202 by 90.

Advancing to step 1:
8 divided by 90 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 90

On to step 2:
90 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 90

Let's proceed to step 3:
90 goes into 891 9 times with a remainder of 81.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 810 from 891 and we're left with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 90

On to step 4:
The number 90 fits into 812 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 810 from 812 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 90

Step 5:
90 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 990.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 90

On to step 6:
202 divided by 90 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 9902.0
Subtract 180 from 202 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
When dividing 220 by 90, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 9902.2
If we subtract 180 from 220, 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 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: 9902.24
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.

Advancing to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 9902.244
Subtract 360 from 400 to 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.

Our division results in 9902.244 with a remaining 0.004.
