40402251 divided by 900 
We want to figure out the number of times 40402251 can be divided by 900.

On to step 1:
If we divide 4 by 900, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 900

Going ahead to step 2:
40 divided by 900 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 900

Let's proceed to step 3:
The number 900 fits into 404 0 times, leaving a remainder of 404.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Append the next digit (0) from the dividend to 404 and continue with: 4040 / 900

Going ahead to step 4:
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: 4.0
Deduct 3600 from 4040 and we're left with 440.
Append the next digit (2) from the dividend to 440 and continue with: 4402 / 900

Going ahead to step 5:
If we divide 4402 by 900, we get 4 and a remainder of 802.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 3600 from 4402 and we're left with 802.
Grab the next digit (2) from the dividend, add it to 802, then carry on: 8022 / 900

Advancing to step 6:
900 goes into 8022 8 times with a remainder of 822.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
If we subtract 7200 from 8022, we get 822.
Append the next digit (5) from the dividend to 822 and continue with: 8225 / 900

Let's proceed to step 7:
When dividing 8225 by 900, we get 9 with a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 4489.0
If we subtract 8100 from 8225, we get 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 900

Step 8:
If we divide 1251 by 900, we get 1 and a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 44891.0
The remainder is 351 after subtracting 900 from 1251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
When dividing 3510 by 900, we get 3 with a remainder of 810.
The next digit of our result is 3. 
Result so far: 44891.3
Subtracting 2700 from 3510 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 10:
8100 divided by 900 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 44891.39
Subtracting 8100 from 8100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 900, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44891.39
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
The number 900 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44891.39
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 44891.39 with a balance of 0.0.
