We look at the division of 720242 by 42 
We're looking to find how many times 42 goes into 720242.

Step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 42

Going ahead to step 2:
The number 42 fits into 72 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 72 to get 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 42

Moving on to step 3:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 294 from 300 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 42

Step 4:
62 divided by 42 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 171.0
Deduct 42 from 62 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 42

Advancing to step 5:
If we divide 204 by 42, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 1714.0
If we take 168 away from 204, we end up with 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 42

Advancing to step 6:
If we divide 362 by 42, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 17148.0
If we subtract 336 from 362, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 42, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 17148.6
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 17148.61
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 17148.619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17148.619
Subtracting 0 from 20 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.

Moving on to step 11:
When dividing 200 by 42, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 17148.61904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 17148.619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
When dividing 260 by 42, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 17148.6190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 17148.61904761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 17148.61904761 with a balance of 3.8e-08.
