We're dividing 73724 by 42 
Our goal is to divide 73724 by 42.

On to step 1:
42 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 42

Moving on to step 2:
When dividing 73 by 42, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 73, we end up with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 42

Going ahead to step 3:
317 divided by 42 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 294 from 317 to get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 42

On to step 4:
42 can be fit into 232 5 times, resulting in a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we subtract 210 from 232, we get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 42

Step 5:
224 divided by 42 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 1755.0
Subtract 210 from 224 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 6:
42 goes into 140 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 1755.3
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 1755.33
Deduct 126 from 140 and we're left 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.

In conclusion, the division gives 1755.33 with a balance of 0.014.
