We're dividing 988830 by 81 
We're looking to find how many times 81 goes into 988830.

Let's proceed to step 1:
If we divide 9 by 81, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 81

Moving on to step 2:
81 goes into 98 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 98 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 81

Going ahead to step 3:
81 can be fit into 178 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 162 from 178, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 81

Going ahead to step 4:
81 goes into 168 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 122.0
Subtracting 162 from 168 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 81

Going ahead to step 5:
When dividing 63 by 81, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 1220.0
If we take 0 away from 63, we end up with 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 81

On to step 6:
81 goes into 630 7 times with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 12207.0
Deduct 567 from 630 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
The number 81 fits into 630 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 12207.7
Subtracting 567 from 630 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
When dividing 630 by 81, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 12207.77
If we take 567 away from 630, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 12207.77 with a remainder of 0.063.
