We divide 88623 by 81
We want to divide 88623 by 81.

Advancing to step 1:
8 divided by 81 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 81

On to step 2:
88 divided by 81 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 88 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 81

Step 3:
The number 81 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 76, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 81

Step 4:
81 can be fit into 762 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 729 away from 762, we end up with 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 81

Let's proceed to step 5:
81 goes into 333 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 1094.0
The remainder is 9 after subtracting 324 from 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
90 divided by 81 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1094.1
Deduct 81 from 90 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 81, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1094.11
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 1094.11 and a remainder of 0.009.
