We're dividing 81385615 by 5 
We want to divide 81385615 by 5.

Step 1:
If we divide 8 by 5, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 5 from 8, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 5

Let's proceed to step 2:
5 goes into 31 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 30 from 31 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 5

Going ahead to step 3:
13 divided by 5 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 162.0
The remainder is 3 after subtracting 10 from 13.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 5

Advancing to step 4:
The number 5 fits into 38 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1627.0
Subtract 35 from 38 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 5

Going ahead to step 5:
5 goes into 35 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 16277.0
If we subtract 35 from 35, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 5

Let's proceed to step 6:
5 can be fit into 6 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 162771.0
The remainder is 1 after subtracting 5 from 6.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 5

Going ahead to step 7:
When dividing 11 by 5, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1627712.0
Subtracting 10 from 11 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 5

Moving on to step 8:
5 goes into 15 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 16277123.0
Subtract 15 from 15 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.

Step 9:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16277123.0
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.

On to step 10:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16277123.0
If we take 0 away from 0, we end up 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.

The quotient of the division is 16277123.0, and the remainder is 0.0.
