We're dividing 427889 by 45 
We want to figure out the number of times 427889 can be divided by 45.

Step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 45

Going ahead to step 2:
If we divide 42 by 45, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 45

Step 3:
45 goes into 427 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 405 from 427 to get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 45

On to step 4:
45 goes into 228 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 225 from 228 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 45

Going ahead to step 5:
When dividing 38 by 45, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 950.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 45

Let's proceed to step 6:
389 divided by 45 is 8 with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 9508.0
Subtracting 360 from 389 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 45, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 9508.6
Subtracting 270 from 290 leaves us 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:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 9508.64
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.

Advancing to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9508.644
Deduct 180 from 200 and we're left 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.

After the division, we end up with 9508.644 and a remainder of 0.002.
