We're dividing 851822 by 90 
Let's see how many times 90 fits into 851822.

Moving on to step 1:
The number 90 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.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 90

On to step 2:
The number 90 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 90

Advancing to step 3:
The number 90 fits into 851 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 810 from 851, we get 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 90

Moving on to step 4:
When dividing 418 by 90, we get 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 360 from 418, we get 58.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 90

Let's proceed to step 5:
If we divide 582 by 90, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 946.0
If we subtract 540 from 582, we get 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 90

On to step 6:
90 can be fit into 422 4 times, resulting in a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 9464.0
If we take 360 away from 422, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
90 can be fit into 620 6 times, resulting in a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 9464.6
Subtract 540 from 620 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 9464.68
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 9464.688
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 9464.688, and the remainder is 0.008.
