We're dividing 65481720 by 815 
We want to figure out the number of times 65481720 can be divided by 815.

Going ahead to step 1:
815 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 815

Moving on to step 2:
815 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 815

On to step 3:
815 goes into 654 0 times with a remainder of 654.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 654 and we're left with 654.
Take the next digit (8) from the dividend and append it to 654, then repeat: 6548 / 815

Going ahead to step 4:
815 goes into 6548 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 28 after subtracting 6520 from 6548.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 815

Going ahead to step 5:
815 can be fit into 281 0 times, resulting in a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 281, we get 281.
Take the next digit (7) from the dividend and append it to 281, then repeat: 2817 / 815

Step 6:
815 goes into 2817 3 times with a remainder of 372.
Write down 3 as next digit of the result. 
Result so far: 803.0
If we subtract 2445 from 2817, we get 372.
Bring next digit (2) of the dividend behind the 372 and repeat the process: 3722 / 815

On to step 7:
The number 815 fits into 3722 4 times, leaving a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 8034.0
Deduct 3260 from 3722 and we're left with 462.
Grab the next digit (0) from the dividend, add it to 462, then carry on: 4620 / 815

On to step 8:
4620 divided by 815 is 5 with a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 80345.0
Subtracting 4075 from 4620 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 9:
When dividing 5450 by 815, we get 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 80345.6
Subtract 4890 from 5450 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
5600 divided by 815 is 6 with a remainder of 710.
Write down 6 as next digit of the result. 
Result so far: 80345.66
The remainder is 710 after subtracting 4890 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final outcome is 80345.66, with a leftover of 0.71.
