We look at the division of 346405 by 48 
The aim is to understand the frequency of 48 in 346405.

Moving on to step 1:
The number 48 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 48

Advancing to step 2:
If we divide 34 by 48, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 48

Going ahead to step 3:
48 goes into 346 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 7.0
If we take 336 away from 346, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 48

Let's proceed to step 4:
48 can be fit into 104 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 96 from 104 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 48

Step 5:
If we divide 80 by 48, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we take 48 away from 80, we end up with 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 48

Moving on to step 6:
325 divided by 48 is 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 7216.0
If we subtract 288 from 325, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 48 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7216.7
Deduct 336 from 370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
If we divide 340 by 48, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7216.77
If we subtract 336 from 340, 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.

After the division, we end up with 7216.77 and a remainder of 0.004.
