Let's divide 998837 by 81
We want to divide 998837 by 81.

Advancing to step 1:
The number 81 fits into 9 0 times, leaving 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.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 81

Going ahead to step 2:
81 can be fit into 99 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 18 after subtracting 81 from 99.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 81

Moving on to step 3:
188 divided by 81 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 162 from 188, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 81

Step 4:
The number 81 fits into 268 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 243 from 268 and we're left with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 81

Let's proceed to step 5:
The number 81 fits into 253 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1233.0
If we subtract 243 from 253, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 81

Going ahead to step 6:
107 divided by 81 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 12331.0
If we take 81 away from 107, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
When dividing 260 by 81, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 12331.3
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12331.32
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 81, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 12331.32
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
81 goes into 800 9 times with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 12331.3209
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 11:
If we divide 710 by 81, we get 8 and a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 12331.32098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
When dividing 620 by 81, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 12331.320987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 13:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 12331.3209876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 81 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12331.32098765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 12331.32098765, and the remainder is 3.5e-08.
