We're dividing 98885885 by 81 
We want to divide 98885885 by 81.

Advancing to step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 81

Step 2:
When dividing 98 by 81, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 81 from 98 leaves us with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 81

Step 3:
The number 81 fits into 178 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 162 from 178 to get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 81

Moving on to step 4:
81 can be fit into 168 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 162 from 168 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 81

On to step 5:
81 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 1220.0
Subtract 0 from 65 to get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 81

On to step 6:
658 divided by 81 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 12208.0
Subtract 648 from 658 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 81

Going ahead to step 7:
The number 81 fits into 108 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 122081.0
Deduct 81 from 108 and we're left with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 81

Step 8:
The number 81 fits into 275 3 times, leaving a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 1220813.0
Subtract 243 from 275 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 81, we get 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 1220813.3
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 10:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 1220813.39
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1220813.395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1220813.395
If we take 0 away from 50, we end up 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.

Step 13:
If we divide 500 by 81, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1220813.39506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
81 goes into 140 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1220813.395061
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 15:
590 divided by 81 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1220813.3950617
Subtracting 567 from 590 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 16:
When dividing 230 by 81, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 1220813.39506172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 1220813.39506172 with a remainder of 6.8e-08.
