We look at the division of 749438 by 6 
The aim is to understand the frequency of 6 in 749438.

Step 1:
6 can be fit into 7 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 6 from 7 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 6

Advancing to step 2:
14 divided by 6 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 2 after subtracting 12 from 14.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 6

On to step 3:
29 divided by 6 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 24 away from 29, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 6

On to step 4:
6 can be fit into 54 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1249.0
If we take 54 away from 54, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 6

Going ahead to step 5:
If we divide 3 by 6, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 12490.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

On to step 6:
6 can be fit into 38 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 124906.0
The remainder is 2 after subtracting 36 from 38.
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 7:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 124906.3
If we take 18 away from 20, we end up 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.

Moving on to step 8:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 124906.33
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.

The final result is 124906.33 with a remainder of 0.002.
