We're dividing 43543369 by 225 
Let's see how many times 225 fits into 43543369.

Advancing to step 1:
4 divided by 225 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 225

Step 2:
225 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 225

Step 3:
The number 225 fits into 435 1 times, leaving a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 225 from 435 to get 210.
Take the next digit (4) from the dividend and append it to 210, then repeat: 2104 / 225

On to step 4:
225 goes into 2104 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 2025 from 2104 to get 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 225

Going ahead to step 5:
When dividing 793 by 225, we get 3 with a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
If we subtract 675 from 793, we get 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 225

Let's proceed to step 6:
If we divide 1183 by 225, we get 5 and a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 1935.0
If we take 1125 away from 1183, we end up with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 225

Step 7:
When dividing 586 by 225, we get 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 19352.0
The remainder is 136 after subtracting 450 from 586.
Include the next digit (9) from the dividend after 136, then repeat: 1369 / 225

Step 8:
The number 225 fits into 1369 6 times, leaving a remainder of 19.
The next digit of our result is 6. 
Result so far: 193526.0
The remainder is 19 after subtracting 1350 from 1369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
If we divide 190 by 225, we get 0 and a remainder of 190.
The next digit of our result is 0. 
Result so far: 193526.0
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
The number 225 fits into 1900 8 times, leaving a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 193526.08
The remainder is 100 after subtracting 1800 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
The number 225 fits into 1000 4 times, leaving a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 193526.084
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.

On to step 12:
The number 225 fits into 1000 4 times, leaving a remainder of 100.
The next digit of our result is 4. 
Result so far: 193526.0844
Subtract 900 from 1000 to 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.

The final outcome is 193526.0844, with a leftover of 0.001.
