91594 ÷ 48 
The aim is to understand the frequency of 48 in 91594.

Moving on to step 1:
If we divide 9 by 48, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 48

On to step 2:
91 divided by 48 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 48 from 91, we get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 48

Let's proceed to step 3:
If we divide 435 by 48, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 432 from 435, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 48

On to step 4:
39 divided by 48 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 48

On to step 5:
When dividing 394 by 48, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1908.0
If we take 384 away from 394, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 6:
100 divided by 48 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1908.2
Subtract 96 from 100 to 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.

Step 7:
If we divide 40 by 48, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1908.2
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
48 goes into 400 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1908.208
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:
160 divided by 48 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 1908.2083
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.

Let's proceed to step 10:
If we divide 160 by 48, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 1908.20833
Subtracting 144 from 160 leaves us 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.

After the division, we end up with 1908.20833 and a remainder of 1.6e-05.
