43486472 ÷ 225 
We want to figure out the number of times 43486472 can be divided by 225.

Moving on to step 1:
When dividing 4 by 225, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 225

Going ahead to step 2:
When dividing 43 by 225, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 225

On to step 3:
225 can be fit into 434 1 times, resulting in a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 225 from 434 to get 209.
Fetch the next digit (8) from the dividend, attach it to 209 and continue: 2098 / 225

Step 4:
The number 225 fits into 2098 9 times, leaving a remainder of 73.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 2025 from 2098 leaves us with 73.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 225

On to step 5:
If we divide 736 by 225, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
Subtracting 675 from 736 leaves us with 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 225

Let's proceed to step 6:
225 can be fit into 614 2 times, resulting in a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 1932.0
Subtracting 450 from 614 leaves us with 164.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 225

Going ahead to step 7:
If we divide 1647 by 225, we get 7 and a remainder of 72.
The next digit of our result is 7. 
Result so far: 19327.0
If we subtract 1575 from 1647, we get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 225

Let's proceed to step 8:
When dividing 722 by 225, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 193273.0
Deduct 675 from 722 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
When dividing 470 by 225, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 193273.2
The remainder is 20 after subtracting 450 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 225 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 193273.2
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
The number 225 fits into 2000 8 times, leaving a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 193273.208
Subtracting 1800 from 2000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
225 can be fit into 2000 8 times, resulting in a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 193273.2088
Subtracting 1800 from 2000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 193273.2088 and a remainder of 0.002.
