80302054 ÷ 6 
The aim is to understand the frequency of 6 in 80302054.

Going ahead to step 1:
If we divide 8 by 6, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 6 from 8 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 6

Advancing to step 2:
If we divide 20 by 6, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
If we take 18 away from 20, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 6

Let's proceed to step 3:
6 can be fit into 23 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 133.0
Deduct 18 from 23 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 6

On to step 4:
6 goes into 50 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1338.0
The remainder is 2 after subtracting 48 from 50.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 6

Let's proceed to step 5:
6 can be fit into 22 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13383.0
The remainder is 4 after subtracting 18 from 22.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 6

Let's proceed to step 6:
The number 6 fits into 40 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 133836.0
The remainder is 4 after subtracting 36 from 40.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 6

Let's proceed to step 7:
6 can be fit into 45 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1338367.0
Deduct 42 from 45 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 6

Step 8:
6 goes into 34 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 13383675.0
Subtract 30 from 34 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.

Advancing to step 9:
If we divide 40 by 6, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13383675.6
If we subtract 36 from 40, we 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 10:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13383675.66
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.

The quotient of the division is 13383675.66, and the remainder is 0.004.
