123645 divided by 6 
The aim is to understand the frequency of 6 in 123645.

Moving on to step 1:
When dividing 1 by 6, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 6

Step 2:
When dividing 12 by 6, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 6

Moving on to step 3:
6 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 6

Let's proceed to step 4:
6 can be fit into 36 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 206.0
Deduct 36 from 36 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 6

Let's proceed to step 5:
When dividing 4 by 6, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 2060.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 6

On to step 6:
The number 6 fits into 45 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 20607.0
The remainder is 3 after subtracting 42 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
6 can be fit into 30 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20607.5
If we subtract 30 from 30, we 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.

On to step 8:
6 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20607.5
Deduct 0 from 0 and we're left 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.

Let's proceed to step 9:
When dividing 0 by 6, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20607.5
If we subtract 0 from 0, we 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.

Our division results in 20607.5 with a remaining 0.0.
