801912 ÷ 31 
Our goal is to divide 801912 by 31.

Let's proceed to step 1:
31 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 31

On to step 2:
When dividing 80 by 31, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 62 from 80 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 31

Advancing to step 3:
The number 31 fits into 181 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 155 from 181 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 31

Going ahead to step 4:
If we divide 269 by 31, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 258.0
Subtract 248 from 269 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 31

Step 5:
If we divide 211 by 31, we get 6 and a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 2586.0
The remainder is 25 after subtracting 186 from 211.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 31

Moving on to step 6:
The number 31 fits into 252 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 25868.0
Subtract 248 from 252 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 25868.1
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 25868.12
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
31 goes into 280 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 25868.129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 25868.129
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 25868.12903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
70 divided by 31 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 25868.129032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 25868.1290322
Deduct 62 from 80 and we're left 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 25868.1290322 with a remaining 1.8e-07.
