We divide 781969 by 15
We want to divide 781969 by 15.

On to step 1:
The number 15 fits into 7 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

Step 2:
When dividing 78 by 15, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 75 from 78 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Let's proceed to step 3:
31 divided by 15 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 1 after subtracting 30 from 31.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

Moving on to step 4:
15 goes into 19 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 521.0
Subtracting 15 from 19 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 15

Moving on to step 5:
If we divide 46 by 15, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 5213.0
Deduct 45 from 46 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

Going ahead to step 6:
15 goes into 19 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 52131.0
Subtracting 15 from 19 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 52131.2
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 52131.26
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 52131.266
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 52131.266, with a leftover of 0.001.
