980905 divided by 90 
We're looking to find how many times 90 goes into 980905.

On to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 90

Advancing to step 2:
90 can be fit into 98 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 90 from 98 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 90

Step 3:
90 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 80, we end up with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 90

On to step 4:
If we divide 809 by 90, we get 8 and a remainder of 89.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 720 from 809, we get 89.
Append the next digit (0) from the dividend to 89 and continue with: 890 / 90

Moving on to step 5:
When dividing 890 by 90, we get 9 with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 1089.0
Deduct 810 from 890 and we're left with 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 90

Step 6:
When dividing 805 by 90, we get 8 with a remainder of 85.
The next digit of our result is 8. 
Result so far: 10898.0
The remainder is 85 after subtracting 720 from 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
90 can be fit into 850 9 times, resulting in a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 10898.9
If we take 810 away from 850, 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.

Advancing to step 8:
400 divided by 90 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 10898.94
If we subtract 360 from 400, 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.

Advancing to step 9:
90 goes into 400 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 10898.944
If we subtract 360 from 400, 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.

The final outcome is 10898.944, with a leftover of 0.004.
