Let's divide 801729 by 31
We're looking to find how many times 31 goes into 801729.

Advancing to step 1:
8 divided by 31 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 31

On to step 2:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 62 away from 80, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 31

Going ahead to step 3:
If we divide 181 by 31, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 155 from 181, we get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 31

On to step 4:
If we divide 267 by 31, we get 8 and a remainder of 19.
The next digit of our result is 8. 
Result so far: 258.0
Subtract 248 from 267 to get 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 31

Moving on to step 5:
31 goes into 192 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 2586.0
If we subtract 186 from 192, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 31

Moving on to step 6:
31 goes into 69 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 25862.0
The remainder is 7 after subtracting 62 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 31 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 25862.2
If we subtract 62 from 70, we 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 8:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 25862.22
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 25862.22 with a remaining 0.018.
