We divide 821845 by 90
Our goal is to divide 821845 by 90.

Let's proceed to step 1:
The number 90 fits into 8 0 times, leaving 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 (2) from the dividend, attach it to 8 and continue: 82 / 90

Advancing to step 2:
When dividing 82 by 90, we get 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 90

Let's proceed to step 3:
If we divide 821 by 90, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 810 away from 821, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 90

Going ahead to step 4:
If we divide 118 by 90, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 90 from 118 leaves us with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 90

Advancing to step 5:
The number 90 fits into 284 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 913.0
If we take 270 away from 284, we end up with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 90

On to step 6:
If we divide 145 by 90, we get 1 and a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 9131.0
Subtract 90 from 145 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
When dividing 550 by 90, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 9131.6
The remainder is 10 after subtracting 540 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 9131.61
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 9131.611
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 9131.611 and a remainder of 0.001.
