We look at the division of 981608 by 81 
We want to divide 981608 by 81.

Going ahead to step 1:
81 goes into 9 0 times with 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.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 81

Advancing to step 2:
98 divided by 81 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 81 from 98 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 81

Moving on to step 3:
When dividing 171 by 81, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 162 from 171 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 81

Moving on to step 4:
The number 81 fits into 96 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 15 after subtracting 81 from 96.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 81

On to step 5:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 1211.0
Subtracting 81 from 150 leaves us with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 81

Step 6:
If we divide 698 by 81, we get 8 and a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 12118.0
Subtracting 648 from 698 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.

Advancing to step 7:
500 divided by 81 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 12118.6
Deduct 486 from 500 and we're left 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.

Advancing to step 8:
81 can be fit into 140 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 12118.61
Deduct 81 from 140 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
When dividing 590 by 81, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 12118.617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
When dividing 230 by 81, we get 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 12118.6172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
81 goes into 680 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 12118.61728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 81, we get 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 12118.617283
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.

Moving on to step 13:
81 goes into 770 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 12118.6172839
If we subtract 729 from 770, we get 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 14:
If we divide 410 by 81, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12118.61728395
If we subtract 405 from 410, we 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.

In conclusion, the division gives 12118.61728395 with a balance of 5e-09.
