We divide 428249 by 45
We want to figure out the number of times 428249 can be divided by 45.

Step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 45

Let's proceed to step 2:
42 divided by 45 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 45

Let's proceed to step 3:
428 divided by 45 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 405 away from 428, we end up with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 45

On to step 4:
If we divide 232 by 45, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 225 from 232, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 45

Step 5:
When dividing 74 by 45, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 951.0
The remainder is 29 after subtracting 45 from 74.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 45

Let's proceed to step 6:
If we divide 299 by 45, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 9516.0
Subtract 270 from 299 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
If we divide 290 by 45, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 9516.6
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 45 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9516.64
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 45 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9516.644
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 9516.644, and the remainder is 0.002.
