We're dividing 43225318 by 45 
We want to divide 43225318 by 45.

On to step 1:
45 can be fit into 4 0 times, resulting in 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 (3) from the dividend, add it to 4, then carry on: 43 / 45

On to step 2:
When dividing 43 by 45, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 45

On to step 3:
When dividing 432 by 45, we get 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 27 after subtracting 405 from 432.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 45

Let's proceed to step 4:
45 can be fit into 272 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 270 from 272, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 45

Advancing to step 5:
45 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 960.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 45

Let's proceed to step 6:
The number 45 fits into 253 5 times, leaving a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 9605.0
If we subtract 225 from 253, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 45

Let's proceed to step 7:
If we divide 281 by 45, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 96056.0
If we take 270 away from 281, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 45

Moving on to step 8:
The number 45 fits into 118 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 960562.0
Subtract 90 from 118 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 45, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 960562.6
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 960562.62
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 45, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 960562.622
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 960562.622 with a remainder of 0.001.
