811915 divided by 6 
The aim is to understand the frequency of 6 in 811915.

Step 1:
6 goes into 8 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 6 away from 8, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 6

Moving on to step 2:
6 can be fit into 21 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 6

Going ahead to step 3:
6 can be fit into 31 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 30 from 31 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 6

Moving on to step 4:
19 divided by 6 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1353.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 6

Moving on to step 5:
When dividing 11 by 6, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 13531.0
If we take 6 away from 11, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 6

Moving on to step 6:
55 divided by 6 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 135319.0
The remainder is 1 after subtracting 54 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
6 goes into 10 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 135319.1
Subtract 6 from 10 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 135319.16
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 135319.166
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 135319.166 with a remainder of 0.0004.
