We look at the division of 81156999 by 6 
We want to figure out the number of times 81156999 can be divided by 6.

Let's proceed to step 1:
If we divide 8 by 6, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 6

Advancing to step 2:
When dividing 21 by 6, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 18 from 21 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 6

Moving on to step 3:
The number 6 fits into 31 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Deduct 30 from 31 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 6

On to step 4:
15 divided by 6 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 1352.0
Deduct 12 from 15 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 6

Going ahead to step 5:
6 goes into 36 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 13526.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 6

On to step 6:
When dividing 9 by 6, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 135261.0
If we take 6 away from 9, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 6

Moving on to step 7:
If we divide 39 by 6, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 1352616.0
Subtract 36 from 39 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 6

On to step 8:
39 divided by 6 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 13526166.0
Deduct 36 from 39 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.

On to step 9:
30 divided by 6 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13526166.5
Subtract 30 from 30 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.

Going ahead to step 10:
If we divide 0 by 6, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13526166.5
Subtracting 0 from 0 leaves us 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.

Step 11:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13526166.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 13526166.5 with a remaining 0.0.
