721992 ÷ 39 
Our goal is to divide 721992 by 39.

Let's proceed to step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 39

Going ahead to step 2:
If we divide 72 by 39, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 39 from 72, we get 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 39

Step 3:
If we divide 331 by 39, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 19 after subtracting 312 from 331.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 39

Going ahead to step 4:
When dividing 199 by 39, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 185.0
The remainder is 4 after subtracting 195 from 199.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 39

Moving on to step 5:
39 can be fit into 49 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1851.0
Subtracting 39 from 49 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 39

Step 6:
39 goes into 102 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 18512.0
Subtracting 78 from 102 leaves us 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.

Going ahead to step 7:
If we divide 240 by 39, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 18512.6
If we take 234 away from 240, 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.

Step 8:
When dividing 60 by 39, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 18512.61
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18512.615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 39 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 18512.6153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 18512.61538
Deduct 312 from 330 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.

Advancing to step 12:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 18512.615384
The remainder is 24 after subtracting 156 from 180.
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 39 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 18512.6153846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
60 divided by 39 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 18512.61538461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 18512.61538461 with a balance of 2.1e-08.
