Let's divide 81311643 by 9
Our goal is to divide 81311643 by 9.

Moving on to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

Step 2:
9 can be fit into 81 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 81 from 81 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

On to step 3:
If we divide 3 by 9, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 9

Let's proceed to step 4:
When dividing 31 by 9, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 903.0
Subtract 27 from 31 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 9

Moving on to step 5:
9 goes into 41 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 9034.0
If we take 36 away from 41, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 9

Going ahead to step 6:
56 divided by 9 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 90346.0
If we take 54 away from 56, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 9

Going ahead to step 7:
24 divided by 9 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 903462.0
Subtract 18 from 24 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 9

Step 8:
9 goes into 63 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 9034627.0
Subtract 63 from 63 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.

Let's proceed to step 9:
9 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9034627.0
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.

Advancing to step 10:
When dividing 0 by 9, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9034627.0
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.

After the division, we end up with 9034627.0 and a remainder of 0.0.
