Let's divide 21374289 by 48
The aim is to understand the frequency of 48 in 21374289.

Step 1:
48 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 48

Moving on to step 2:
If we divide 21 by 48, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 48

Going ahead to step 3:
The number 48 fits into 213 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 21 after subtracting 192 from 213.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 48

On to step 4:
When dividing 217 by 48, we get 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 25 after subtracting 192 from 217.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 48

Moving on to step 5:
If we divide 254 by 48, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 445.0
Deduct 240 from 254 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 48

Going ahead to step 6:
48 goes into 142 2 times with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 4452.0
If we take 96 away from 142, we end up with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 48

Step 7:
48 can be fit into 468 9 times, resulting in a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 44529.0
Subtract 432 from 468 to get 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 48

Let's proceed to step 8:
369 divided by 48 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 445297.0
Subtracting 336 from 369 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 48, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 445297.6
The remainder is 42 after subtracting 288 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
48 can be fit into 420 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 445297.68
If we subtract 384 from 420, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
48 can be fit into 360 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 445297.687
If we subtract 336 from 360, 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.

Advancing to step 12:
48 can be fit into 240 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 445297.6875
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
0 divided by 48 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 445297.6875
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.

Let's proceed to step 14:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 445297.6875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 445297.6875 and a remainder of 0.0.
