We divide 781713 by 15
We're looking to find how many times 15 goes into 781713.

Going ahead to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

Let's proceed to step 2:
The number 15 fits into 78 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 75 from 78, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Advancing to step 3:
When dividing 31 by 15, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 30 from 31, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 15

Advancing to step 4:
15 goes into 17 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 521.0
Subtract 15 from 17 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 15

Let's proceed to step 5:
21 divided by 15 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 5211.0
If we subtract 15 from 21, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

On to step 6:
63 divided by 15 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 52114.0
The remainder is 3 after subtracting 60 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 52114.2
Deduct 30 from 30 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 52114.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 52114.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 52114.2 and a remainder of 0.0.
