Let's divide 840899 by 90
We want to divide 840899 by 90.

Let's proceed to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 90

Step 2:
If we divide 84 by 90, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 90

Advancing to step 3:
The number 90 fits into 840 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 810 from 840 leaves us with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 90

On to step 4:
90 goes into 308 3 times with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 270 away from 308, we end up with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 90

Let's proceed to step 5:
90 can be fit into 389 4 times, resulting in a remainder of 29.
The next digit of our result is 4. 
Result so far: 934.0
If we subtract 360 from 389, we get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 90

On to step 6:
299 divided by 90 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 9343.0
If we subtract 270 from 299, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
90 can be fit into 290 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 9343.3
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 9343.32
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 9343.322
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 9343.322 with a remaining 0.002.
