68991412 ÷ 6 
The aim is to understand the frequency of 6 in 68991412.

On to step 1:
6 can be fit into 6 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 6 from 6 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 6

On to step 2:
If we divide 8 by 6, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 6

Let's proceed to step 3:
If we divide 29 by 6, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we subtract 24 from 29, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 6

Let's proceed to step 4:
If we divide 59 by 6, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 1149.0
If we subtract 54 from 59, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 6

Moving on to step 5:
The number 6 fits into 51 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 11498.0
If we subtract 48 from 51, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 6

Moving on to step 6:
34 divided by 6 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 114985.0
If we take 30 away from 34, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 6

On to step 7:
If we divide 41 by 6, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 1149856.0
Subtracting 36 from 41 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 6

Let's proceed to step 8:
52 divided by 6 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11498568.0
Subtract 48 from 52 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.

Step 9:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11498568.6
Subtracting 36 from 40 leaves us 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.

Going ahead to step 10:
6 goes into 40 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 11498568.66
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.

After the division, we end up with 11498568.66 and a remainder of 0.004.
