913458 divided by 81 
We want to figure out the number of times 913458 can be divided by 81.

On to step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 81

On to step 2:
91 divided by 81 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 81 from 91 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 81

Moving on to step 3:
If we divide 103 by 81, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 81 from 103, we get 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 81

Going ahead to step 4:
If we divide 224 by 81, we get 2 and a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 162 from 224, we get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 81

Going ahead to step 5:
81 can be fit into 625 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 1127.0
If we take 567 away from 625, we end up with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 81

Going ahead to step 6:
81 can be fit into 588 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 11277.0
Subtracting 567 from 588 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 81, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 11277.2
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
The number 81 fits into 480 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 11277.25
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
81 goes into 750 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 11277.259
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
When dividing 210 by 81, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 11277.2592
Subtracting 162 from 210 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 11277.25925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
When dividing 750 by 81, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 11277.259259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
210 divided by 81 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 11277.2592592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
When dividing 480 by 81, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 11277.25925925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 11277.25925925, and the remainder is 7.5e-08.
