We look at the division of 492142 by 45 
We want to divide 492142 by 45.

Going ahead to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 45

Going ahead to step 2:
If we divide 49 by 45, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 49 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 45

Going ahead to step 3:
45 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 45

On to step 4:
If we divide 421 by 45, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 405 from 421, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 45

Moving on to step 5:
If we divide 164 by 45, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 1093.0
Subtract 135 from 164 to get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 45

Advancing to step 6:
If we divide 292 by 45, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 10936.0
The remainder is 22 after subtracting 270 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
45 goes into 220 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 10936.4
If we take 180 away from 220, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 10936.48
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 10936.488
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 10936.488 and a remainder of 0.004.
