We look at the division of 742123 by 29 
Our goal is to divide 742123 by 29.

Going ahead to step 1:
If we divide 7 by 29, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 29

Moving on to step 2:
29 can be fit into 74 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 58 from 74 and we're left with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 29

Moving on to step 3:
162 divided by 29 is 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 145 from 162 leaves us with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 29

Let's proceed to step 4:
If we divide 171 by 29, we get 5 and a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
If we take 145 away from 171, we end up with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 29

Moving on to step 5:
When dividing 262 by 29, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2559.0
The remainder is 1 after subtracting 261 from 262.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 29

Going ahead to step 6:
If we divide 13 by 29, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 25590.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 25590.4
If we take 116 away from 130, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 29 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 25590.44
The remainder is 24 after subtracting 116 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 25590.44, and the remainder is 0.024.
