We're dividing 723285 by 42 
Let's see how many times 42 fits into 723285.

Step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 42

Advancing to step 2:
72 divided by 42 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 72, we get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 42

Moving on to step 3:
When dividing 303 by 42, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 294 from 303 leaves us with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Moving on to step 4:
If we divide 92 by 42, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtract 84 from 92 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 42

Let's proceed to step 5:
When dividing 88 by 42, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1722.0
The remainder is 4 after subtracting 84 from 88.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

Let's proceed to step 6:
42 goes into 45 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 17221.0
The remainder is 3 after subtracting 42 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 17221.0
If we subtract 0 from 30, we 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.

Moving on to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 17221.07
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.

Advancing to step 9:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 17221.071
Subtract 42 from 60 to 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.

On to step 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 17221.0714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
42 goes into 120 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 17221.07142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 17221.071428
If we take 336 away from 360, we end up 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 13:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17221.0714285
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.

Going ahead to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17221.07142857
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.

Our division results in 17221.07142857 with a remaining 6e-09.
