Let's divide 405797 by 81
We want to figure out the number of times 405797 can be divided by 81.

On to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 81

On to step 2:
If we divide 40 by 81, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 81

Let's proceed to step 3:
If we divide 405 by 81, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 405 from 405 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 81

Going ahead to step 4:
7 divided by 81 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 81

Step 5:
If we divide 79 by 81, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 500.0
If we subtract 0 from 79, we get 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 81

Let's proceed to step 6:
When dividing 797 by 81, we get 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 5009.0
The remainder is 68 after subtracting 729 from 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
When dividing 680 by 81, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5009.8
The remainder is 32 after subtracting 648 from 680.
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 8:
When dividing 320 by 81, we get 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 5009.83
Deduct 243 from 320 and we're left with 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 9:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 5009.839
If we take 729 away from 770, we end up 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.

Advancing to step 10:
If we divide 410 by 81, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 5009.8395
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.

On to step 11:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5009.8395
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.

Going ahead to step 12:
If we divide 500 by 81, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 5009.839506
Subtracting 486 from 500 leaves us 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 13:
81 goes into 140 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 5009.8395061
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.

Going ahead to step 14:
590 divided by 81 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 5009.83950617
If we take 567 away from 590, we end up 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.

The final outcome is 5009.83950617, with a leftover of 2.3e-08.
