81290650 divided by 15 
Our goal is to divide 81290650 by 15.

Step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 15

Going ahead to step 2:
15 goes into 81 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 6 after subtracting 75 from 81.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 15

Advancing to step 3:
The number 15 fits into 62 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 60 from 62 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 15

Let's proceed to step 4:
15 goes into 29 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 541.0
Deduct 15 from 29 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 15

Step 5:
If we divide 140 by 15, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 5419.0
Subtract 135 from 140 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 15

Moving on to step 6:
The number 15 fits into 56 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 54193.0
Subtracting 45 from 56 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 15

Going ahead to step 7:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 541937.0
If we take 105 away from 115, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 15

Moving on to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 5419376.0
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 5419376.6
Subtract 90 from 100 to 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 10:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 5419376.66
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.

Our division results in 5419376.66 with a remaining 0.01.
