We divide 147421 by 6
The aim is to understand the frequency of 6 in 147421.

Step 1:
The number 6 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 6

On to step 2:
If we divide 14 by 6, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 12 from 14 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 6

Step 3:
6 goes into 27 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 24 from 27 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 6

Advancing to step 4:
If we divide 34 by 6, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 245.0
Subtract 30 from 34 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 6

Advancing to step 5:
42 divided by 6 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2457.0
If we subtract 42 from 42, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 6

On to step 6:
The number 6 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 24570.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 6, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 24570.1
If we take 6 away from 10, 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.

Advancing to step 8:
40 divided by 6 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 24570.16
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.

Advancing to step 9:
6 goes into 40 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 24570.166
The remainder is 4 after subtracting 36 from 40.
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 24570.166 with a remainder of 0.0004.
