Let's divide 11555458 by 900
We want to figure out the number of times 11555458 can be divided by 900.

Going ahead to step 1:
1 divided by 900 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 900

Let's proceed to step 2:
900 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 900

Step 3:
When dividing 115 by 900, we get 0 with a remainder of 115.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 115, we get 115.
Bring next digit (5) of the dividend behind the 115 and repeat the process: 1155 / 900

Advancing to step 4:
900 goes into 1155 1 times with a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 900 from 1155 and we're left with 255.
Include the next digit (5) from the dividend after 255, then repeat: 2555 / 900

Advancing to step 5:
The number 900 fits into 2555 2 times, leaving a remainder of 755.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1800 from 2555 and we're left with 755.
Include the next digit (4) from the dividend after 755, then repeat: 7554 / 900

Going ahead to step 6:
If we divide 7554 by 900, we get 8 and a remainder of 354.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 7200 from 7554 leaves us with 354.
Grab the next digit (5) from the dividend, add it to 354, then carry on: 3545 / 900

Going ahead to step 7:
The number 900 fits into 3545 3 times, leaving a remainder of 845.
Record the quotient 3 as the next digit in the result. 
Result so far: 1283.0
Deduct 2700 from 3545 and we're left with 845.
Append the next digit (8) from the dividend to 845 and continue with: 8458 / 900

Advancing to step 8:
8458 divided by 900 is 9 with a remainder of 358.
Record the quotient 9 as the next digit in the result. 
Result so far: 12839.0
Subtracting 8100 from 8458 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 9:
3580 divided by 900 is 3 with a remainder of 880.
The number 3 becomes the next digit in our result. 
Result so far: 12839.3
Subtract 2700 from 3580 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Advancing to step 10:
If we divide 8800 by 900, we get 9 and a remainder of 700.
Write down 9 as next digit of the result. 
Result so far: 12839.39
Subtract 8100 from 8800 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
900 can be fit into 7000 7 times, resulting in a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 12839.397
Deduct 6300 from 7000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
The number 900 fits into 7000 7 times, leaving a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 12839.3977
Subtract 6300 from 7000 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

After the division, we end up with 12839.3977 and a remainder of 0.007.
