Let's divide 305380 by 48
The aim is to understand the frequency of 48 in 305380.

Step 1:
3 divided by 48 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 48

On to step 2:
48 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 48

Advancing to step 3:
305 divided by 48 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 288 from 305, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 48

Let's proceed to step 4:
If we divide 173 by 48, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Deduct 144 from 173 and we're left with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 48

On to step 5:
If we divide 298 by 48, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 636.0
Deduct 288 from 298 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 48

Going ahead to step 6:
The number 48 fits into 100 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6362.0
Subtracting 96 from 100 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.

On to step 7:
When dividing 40 by 48, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6362.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
If we divide 400 by 48, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6362.08
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 6362.083
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 6362.0833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 6362.0833, and the remainder is 0.00016.
