45645175 divided by 900 
We want to figure out the number of times 45645175 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
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 900

Let's proceed to step 2:
900 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 900

Let's proceed to step 3:
456 divided by 900 is 0 with a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 456, we get 456.
Include the next digit (4) from the dividend after 456, then repeat: 4564 / 900

Going ahead to step 4:
When dividing 4564 by 900, we get 5 with a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4500 from 4564, we get 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 900

On to step 5:
645 divided by 900 is 0 with a remainder of 645.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 645, we end up with 645.
Take the next digit (1) from the dividend and append it to 645, then repeat: 6451 / 900

Step 6:
900 can be fit into 6451 7 times, resulting in a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we subtract 6300 from 6451, we get 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 900

Going ahead to step 7:
The number 900 fits into 1517 1 times, leaving a remainder of 617.
The next digit of our result is 1. 
Result so far: 5071.0
Subtracting 900 from 1517 leaves us with 617.
Grab the next digit (5) from the dividend, add it to 617, then carry on: 6175 / 900

On to step 8:
The number 900 fits into 6175 6 times, leaving a remainder of 775.
The next digit of our result is 6. 
Result so far: 50716.0
Subtract 5400 from 6175 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 9:
When dividing 7750 by 900, we get 8 with a remainder of 550.
The next digit of our result is 8. 
Result so far: 50716.8
The remainder is 550 after subtracting 7200 from 7750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
When dividing 5500 by 900, we get 6 with a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 50716.86
If we subtract 5400 from 5500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 900 fits into 1000 1 times, leaving a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 50716.861
If we take 900 away from 1000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
900 goes into 1000 1 times with a remainder of 100.
The next digit of our result is 1. 
Result so far: 50716.8611
The remainder is 100 after subtracting 900 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 50716.8611 and a remainder of 0.001.
