We look at the division of 838069 by 81 
We're looking to find how many times 81 goes into 838069.

Step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 81

Going ahead to step 2:
83 divided by 81 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 83, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 81

On to step 3:
When dividing 28 by 81, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 81

Moving on to step 4:
If we divide 280 by 81, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 243 from 280 and we're left with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 81

Let's proceed to step 5:
The number 81 fits into 376 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 1034.0
Subtracting 324 from 376 leaves us with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 81

Let's proceed to step 6:
If we divide 529 by 81, we get 6 and a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 10346.0
If we take 486 away from 529, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10346.5
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
When dividing 250 by 81, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 10346.53
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
81 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10346.53
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 81, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 10346.5308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
If we divide 520 by 81, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 10346.53086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
When dividing 340 by 81, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 10346.530864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
If we divide 160 by 81, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 10346.5308641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
If we divide 790 by 81, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 10346.53086419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 10346.53086419, with a leftover of 6.1e-08.
