We look at the division of 732439 by 42 
Let's see how many times 42 fits into 732439.

Let's proceed to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 42

Going ahead 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 subtract 42 from 73, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 42

Let's proceed to step 3:
312 divided by 42 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 294 from 312 and we're left with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 42

On to step 4:
42 goes into 184 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 174.0
Deduct 168 from 184 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 42

Moving on to step 5:
42 goes into 163 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1743.0
The remainder is 37 after subtracting 126 from 163.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 42

Advancing to step 6:
When dividing 379 by 42, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 17439.0
Subtract 378 from 379 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
42 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17439.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 17439.02
If we take 84 away from 100, we end up with 16.
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 9:
42 goes into 160 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 17439.023
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.

On to step 10:
When dividing 340 by 42, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 17439.0238
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.

Advancing to step 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17439.0238
Subtracting 0 from 40 leaves us with 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 12:
If we divide 400 by 42, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 17439.023809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 17439.0238095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 17439.02380952
Subtract 84 from 100 to 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.

The final result is 17439.02380952 with a remainder of 1.6e-08.
