81502356 ÷ 9 
We want to figure out the number of times 81502356 can be divided by 9.

Moving on to step 1:
9 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 9

Step 2:
When dividing 81 by 9, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 81 from 81, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 9

Advancing to step 3:
When dividing 5 by 9, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 9

Going ahead to step 4:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 905.0
Deduct 45 from 50 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Moving on to step 5:
9 can be fit into 52 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 9055.0
If we take 45 away from 52, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 9

Let's proceed to step 6:
When dividing 73 by 9, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 90558.0
Subtract 72 from 73 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 9

Advancing to step 7:
9 goes into 15 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 905581.0
The remainder is 6 after subtracting 9 from 15.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Let's proceed to step 8:
The number 9 fits into 66 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 9055817.0
Deduct 63 from 66 and we're left with 3.
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 9:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 9055817.3
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 9055817.33
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 9055817.33, with a leftover of 0.003.
