Let's divide 80394718 by 225
We want to figure out the number of times 80394718 can be divided by 225.

Advancing to step 1:
When dividing 8 by 225, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 225

Let's proceed to step 2:
If we divide 80 by 225, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 225

Going ahead to step 3:
225 goes into 803 3 times with a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 128 after subtracting 675 from 803.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 225

On to step 4:
225 can be fit into 1289 5 times, resulting in a remainder of 164.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 1125 from 1289, we get 164.
Fetch the next digit (4) from the dividend, attach it to 164 and continue: 1644 / 225

On to step 5:
225 can be fit into 1644 7 times, resulting in a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 357.0
The remainder is 69 after subtracting 1575 from 1644.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 225

Let's proceed to step 6:
225 can be fit into 697 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 3573.0
Subtracting 675 from 697 leaves us with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 225

Let's proceed to step 7:
225 goes into 221 0 times with a remainder of 221.
Record the quotient 0 as the next digit in the result. 
Result so far: 35730.0
Deduct 0 from 221 and we're left with 221.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 225

Going ahead to step 8:
The number 225 fits into 2218 9 times, leaving a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 357309.0
Subtracting 2025 from 2218 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 9:
The number 225 fits into 1930 8 times, leaving a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 357309.8
If we subtract 1800 from 1930, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 225, we get 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 357309.85
Subtracting 1125 from 1300 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
225 can be fit into 1750 7 times, resulting in a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 357309.857
The remainder is 175 after subtracting 1575 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
When dividing 1750 by 225, we get 7 with a remainder of 175.
Put 7 as the next digit of the answer. 
Result so far: 357309.8577
If we subtract 1575 from 1750, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 357309.8577 with a remaining 0.00175.
