We look at the division of 904405 by 31 
We want to divide 904405 by 31.

Step 1:
9 divided by 31 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 31

Going ahead to step 2:
90 divided by 31 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 62 away from 90, we end up with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 31

Advancing to step 3:
When dividing 284 by 31, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 279 from 284 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 31

Let's proceed to step 4:
31 goes into 54 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 291.0
The remainder is 23 after subtracting 31 from 54.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 31

Step 5:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2917.0
The remainder is 13 after subtracting 217 from 230.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 31

Going ahead to step 6:
If we divide 135 by 31, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 29174.0
Deduct 124 from 135 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 31, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 29174.3
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
If we divide 170 by 31, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 29174.35
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 29174.354
Subtracting 124 from 150 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 29174.3548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 29174.35483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 29174.354838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
31 goes into 220 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 29174.3548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
31 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 29174.3548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 29174.3548387 with a remaining 3e-08.
