We look at the division of 253571 by 48 
The aim is to understand the frequency of 48 in 253571.

Advancing to step 1:
48 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 48

On to step 2:
48 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 48

Advancing to step 3:
When dividing 253 by 48, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 240 away from 253, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 48

Step 4:
If we divide 135 by 48, we get 2 and a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 96 away from 135, we end up with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 48

Moving on to step 5:
397 divided by 48 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 528.0
Deduct 384 from 397 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 48

Advancing to step 6:
If we divide 131 by 48, we get 2 and a remainder of 35.
The next digit of our result is 2. 
Result so far: 5282.0
Subtract 96 from 131 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
The number 48 fits into 350 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 5282.7
Subtract 336 from 350 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 48, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 5282.72
Subtract 96 from 140 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
440 divided by 48 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 5282.729
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 48 is 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 5282.7291
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
48 goes into 320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 5282.72916
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5282.729166
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 5282.729166 and a remainder of 3.2e-06.
