We look at the division of 721416 by 39 
Let's see how many times 39 fits into 721416.

Going ahead to step 1:
7 divided by 39 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 39

Let's proceed to step 2:
72 divided by 39 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 72 to get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 39

Moving on to step 3:
331 divided by 39 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 312 away from 331, we end up with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 39

On to step 4:
194 divided by 39 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Deduct 156 from 194 and we're left with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 39

Moving on to step 5:
39 goes into 381 9 times with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 1849.0
Subtract 351 from 381 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 39

Let's proceed to step 6:
When dividing 306 by 39, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 18497.0
If we take 273 away from 306, 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 7:
If we divide 330 by 39, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 18497.8
If we subtract 312 from 330, 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.

Going ahead to step 8:
When dividing 180 by 39, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 18497.84
Subtract 156 from 180 to 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.

Moving on to step 9:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 18497.846
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.

Step 10:
39 goes into 60 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 18497.8461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
If we divide 210 by 39, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 18497.84615
If we subtract 195 from 210, we get 15.
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 12:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 18497.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 18497.8461538
Subtracting 312 from 330 leaves us 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.

Let's proceed to step 14:
When dividing 180 by 39, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 18497.84615384
Deduct 156 from 180 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.

The quotient of the division is 18497.84615384, and the remainder is 2.4e-08.
