51404360 divided by 6 
The aim is to understand the frequency of 6 in 51404360.

Moving on to step 1:
When dividing 5 by 6, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 6

On to step 2:
The number 6 fits into 51 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 3 after subtracting 48 from 51.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 6

Moving on to step 3:
6 can be fit into 34 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 85.0
If we take 30 away from 34, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 6

Going ahead to step 4:
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: 856.0
Deduct 36 from 40 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 6

Let's proceed to step 5:
6 goes into 44 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 8567.0
Subtracting 42 from 44 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 6

Step 6:
If we divide 23 by 6, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 85673.0
If we take 18 away from 23, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 6

Going ahead to step 7:
The number 6 fits into 56 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 856739.0
The remainder is 2 after subtracting 54 from 56.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 6

Let's proceed to step 8:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8567393.0
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
If we divide 20 by 6, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 8567393.3
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8567393.33
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 8567393.33 with a balance of 0.002.
