31351223 divided by 900 
We want to divide 31351223 by 900.

Going ahead to step 1:
900 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 900

Step 2:
When dividing 31 by 900, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 900

Advancing to step 3:
900 can be fit into 313 0 times, resulting in a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Include the next digit (5) from the dividend after 313, then repeat: 3135 / 900

Step 4:
If we divide 3135 by 900, we get 3 and a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2700 away from 3135, we end up with 435.
Fetch the next digit (1) from the dividend, attach it to 435 and continue: 4351 / 900

Let's proceed to step 5:
900 can be fit into 4351 4 times, resulting in a remainder of 751.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 3600 from 4351 and we're left with 751.
Grab the next digit (2) from the dividend, add it to 751, then carry on: 7512 / 900

On to step 6:
900 can be fit into 7512 8 times, resulting in a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 348.0
Subtract 7200 from 7512 to get 312.
Append the next digit (2) from the dividend to 312 and continue with: 3122 / 900

Let's proceed to step 7:
If we divide 3122 by 900, we get 3 and a remainder of 422.
The number 3 becomes the next digit in our result. 
Result so far: 3483.0
If we take 2700 away from 3122, we end up with 422.
Fetch the next digit (3) from the dividend, attach it to 422 and continue: 4223 / 900

On to step 8:
When dividing 4223 by 900, we get 4 with a remainder of 623.
Write down 4 as next digit of the result. 
Result so far: 34834.0
If we subtract 3600 from 4223, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 9:
900 goes into 6230 6 times with a remainder of 830.
Write down 6 as next digit of the result. 
Result so far: 34834.6
Subtract 5400 from 6230 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Step 10:
The number 900 fits into 8300 9 times, leaving a remainder of 200.
Use 9 as the next digit of our solution. 
Result so far: 34834.69
Subtracting 8100 from 8300 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
900 can be fit into 2000 2 times, resulting in a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 34834.692
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
The number 900 fits into 2000 2 times, leaving a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 34834.6922
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 34834.6922, and the remainder is 0.002.
