Let's divide 728139 by 42
Our goal is to divide 728139 by 42.

Moving on to step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

On to step 2:
When dividing 72 by 42, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 72 to get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 42

Going ahead to step 3:
The number 42 fits into 308 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 294 from 308 leaves us with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 42

Step 4:
When dividing 141 by 42, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 173.0
The remainder is 15 after subtracting 126 from 141.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 42

Going ahead to step 5:
When dividing 153 by 42, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1733.0
Deduct 126 from 153 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 42

Going ahead to step 6:
If we divide 279 by 42, we get 6 and a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 17336.0
Subtracting 252 from 279 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
42 can be fit into 270 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 17336.6
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 17336.64
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 17336.642
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 17336.6428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 17336.64285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17336.642857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 17336.6428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17336.64285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 17336.64285714, and the remainder is 1.2e-08.
