We divide 142923 by 45
Our goal is to divide 142923 by 45.

On to step 1:
45 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 45

Step 2:
The number 45 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 45

Advancing to step 3:
142 divided by 45 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 7 after subtracting 135 from 142.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 45

On to step 4:
45 goes into 79 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 31.0
If we take 45 away from 79, we end up with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 45

Moving on to step 5:
45 can be fit into 342 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 317.0
Deduct 315 from 342 and we're left with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 45

Let's proceed to step 6:
45 can be fit into 273 6 times, resulting in a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 3176.0
The remainder is 3 after subtracting 270 from 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
45 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3176.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 3176.06
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 3176.066
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 3176.066 and a remainder of 0.003.
