We look at the division of 836343 by 80 
We want to figure out the number of times 836343 can be divided by 80.

On to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 80

Let's proceed to step 2:
83 divided by 80 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 83 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 80

Step 3:
36 divided by 80 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 80

Let's proceed to step 4:
When dividing 363 by 80, we get 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we subtract 320 from 363, we get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 80

Step 5:
434 divided by 80 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1045.0
Deduct 400 from 434 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 80

Moving on to step 6:
If we divide 343 by 80, we get 4 and a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 10454.0
Subtract 320 from 343 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 7:
80 can be fit into 230 2 times, resulting in a remainder of 70.
The next digit of our result is 2. 
Result so far: 10454.2
Subtracting 160 from 230 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
700 divided by 80 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 10454.28
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10454.287
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10454.2875
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10454.2875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10454.2875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10454.2875, with a leftover of 0.0.
