We're dividing 403297 by 45 
Let's see how many times 45 fits into 403297.

On to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 45

Advancing to step 2:
If we divide 40 by 45, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 45

Step 3:
403 divided by 45 is 8 with a remainder of 43.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 360 from 403, we get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 45

Step 4:
45 goes into 432 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 405 from 432 to get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 45

Advancing to step 5:
45 goes into 279 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 896.0
Subtract 270 from 279 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 45

Step 6:
The number 45 fits into 97 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 8962.0
Deduct 90 from 97 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 45, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 8962.1
Subtracting 45 from 70 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
45 goes into 250 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8962.15
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8962.155
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 8962.155 and a remainder of 0.0025.
