We look at the division of 30631040 by 900 
Let's see how many times 900 fits into 30631040.

Moving on to step 1:
3 divided by 900 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 900

Going ahead to step 2:
30 divided by 900 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 900

On to step 3:
The number 900 fits into 306 0 times, leaving a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 306 to get 306.
Fetch the next digit (3) from the dividend, attach it to 306 and continue: 3063 / 900

Step 4:
3063 divided by 900 is 3 with a remainder of 363.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2700 from 3063 to get 363.
Grab the next digit (1) from the dividend, add it to 363, then carry on: 3631 / 900

Advancing to step 5:
The number 900 fits into 3631 4 times, leaving a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 3600 from 3631 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 900

Advancing to step 6:
The number 900 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 340.0
Subtracting 0 from 310 leaves us with 310.
Take the next digit (4) from the dividend and append it to 310, then repeat: 3104 / 900

Moving on to step 7:
When dividing 3104 by 900, we get 3 with a remainder of 404.
Record the quotient 3 as the next digit in the result. 
Result so far: 3403.0
Subtract 2700 from 3104 to get 404.
Bring next digit (0) of the dividend behind the 404 and repeat the process: 4040 / 900

Advancing to step 8:
900 can be fit into 4040 4 times, resulting in a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 34034.0
Subtract 3600 from 4040 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 9:
900 can be fit into 4400 4 times, resulting in a remainder of 800.
Write down 4 as next digit of the result. 
Result so far: 34034.4
Deduct 3600 from 4400 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 10:
900 can be fit into 8000 8 times, resulting in a remainder of 800.
Put 8 as the next digit of the answer. 
Result so far: 34034.48
The remainder is 800 after subtracting 7200 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
900 can be fit into 8000 8 times, resulting in a remainder of 800.
Record the quotient 8 as the next digit in the result. 
Result so far: 34034.488
Subtract 7200 from 8000 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 34034.488 with a remainder of 0.08.
