We look at the division of 16887045 by 225 
Let's see how many times 225 fits into 16887045.

On to step 1:
When dividing 1 by 225, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 225

On to step 2:
The number 225 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 225

On to step 3:
225 goes into 168 0 times with a remainder of 168.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 168 leaves us with 168.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 225

Going ahead to step 4:
When dividing 1688 by 225, we get 7 with a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 113 after subtracting 1575 from 1688.
Append the next digit (7) from the dividend to 113 and continue with: 1137 / 225

Let's proceed to step 5:
The number 225 fits into 1137 5 times, leaving a remainder of 12.
The next digit of our result is 5. 
Result so far: 75.0
Subtract 1125 from 1137 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 225

Let's proceed to step 6:
The number 225 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 750.0
If we take 0 away from 120, we end up with 120.
Bring next digit (4) of the dividend behind the 120 and repeat the process: 1204 / 225

Let's proceed to step 7:
If we divide 1204 by 225, we get 5 and a remainder of 79.
Write down 5 as next digit of the result. 
Result so far: 7505.0
Subtract 1125 from 1204 to get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 225

Advancing to step 8:
If we divide 795 by 225, we get 3 and a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 75053.0
If we take 675 away from 795, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
225 can be fit into 1200 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 75053.5
The remainder is 75 after subtracting 1125 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
225 goes into 750 3 times with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 75053.53
Subtract 675 from 750 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
The number 225 fits into 750 3 times, leaving a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 75053.533
The remainder is 75 after subtracting 675 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 75053.533 and a remainder of 0.0075.
