We look at the division of 715402 by 42 
Let's see how many times 42 fits into 715402.

Advancing to step 1:
7 divided by 42 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 42

Going ahead to step 2:
When dividing 71 by 42, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 29 after subtracting 42 from 71.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 42

Advancing to step 3:
The number 42 fits into 295 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 294 from 295 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 42

Moving on to step 4:
The number 42 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 42

Step 5:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1703.0
If we take 126 away from 140, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 42

Let's proceed to step 6:
42 goes into 142 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 17033.0
The remainder is 16 after subtracting 126 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 17033.3
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 17033.38
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 17033.38
If we subtract 0 from 40, 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.

Step 10:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 17033.3809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 17033.38095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 42, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 17033.380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 17033.3809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17033.38095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 17033.38095238 with a balance of 4e-09.
