We're dividing 534558 by 48 
The aim is to understand the frequency of 48 in 534558.

On to step 1:
48 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 48

Going ahead to step 2:
If we divide 53 by 48, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 48 from 53 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 48

Advancing to step 3:
54 divided by 48 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 6 after subtracting 48 from 54.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 48

Moving on to step 4:
If we divide 65 by 48, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 48 from 65 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 48

Step 5:
The number 48 fits into 175 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 1113.0
Deduct 144 from 175 and we're left with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 48

On to step 6:
The number 48 fits into 318 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 11136.0
Subtract 288 from 318 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
The number 48 fits into 300 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 11136.6
The remainder is 12 after subtracting 288 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 48, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 11136.62
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11136.625
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11136.625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11136.625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11136.625, with a leftover of 0.0.
