We look at the division of 980843 by 90 
Our goal is to divide 980843 by 90.

Going ahead to step 1:
90 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 90

Advancing to step 2:
When dividing 98 by 90, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 90 from 98 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 90

Going ahead to step 3:
80 divided by 90 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 90

Step 4:
90 goes into 808 8 times with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 88 after subtracting 720 from 808.
Grab the next digit (4) from the dividend, add it to 88, then carry on: 884 / 90

Moving on to step 5:
When dividing 884 by 90, we get 9 with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
Subtracting 810 from 884 leaves us with 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 90

Let's proceed to step 6:
743 divided by 90 is 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 10898.0
Subtracting 720 from 743 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
90 goes into 230 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 10898.2
Deduct 180 from 230 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10898.25
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 10898.255
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 10898.255, with a leftover of 0.005.
