723207 divided by 42 
Let's see how many times 42 fits into 723207.

Step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

Step 2:
When dividing 72 by 42, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 72 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 42

Moving on to step 3:
If we divide 303 by 42, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 294 from 303 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Let's proceed to step 4:
When dividing 92 by 42, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtract 84 from 92 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 42

Going ahead to step 5:
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: 1721.0
Subtract 42 from 80 to get 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 42

On to step 6:
42 can be fit into 387 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 17219.0
Subtract 378 from 387 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 17219.2
If we subtract 84 from 90, we get 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 8:
If we divide 60 by 42, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 17219.21
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17219.214
Subtracting 168 from 180 leaves us 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.

Advancing to step 10:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 17219.2142
The remainder is 36 after subtracting 84 from 120.
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 11:
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: 17219.21428
If we subtract 336 from 360, we get 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 12:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 17219.214285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 17219.2142857
Deduct 294 from 300 and we're left 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 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 17219.21428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 17219.21428571 with a remaining 1.8e-08.
