We look at the division of 286221 by 48 
The aim is to understand the frequency of 48 in 286221.

Going ahead to step 1:
If we divide 2 by 48, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 48

Step 2:
28 divided by 48 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 48

Let's proceed to step 3:
The number 48 fits into 286 5 times, leaving a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 240 from 286 and we're left with 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 48

Step 4:
If we divide 462 by 48, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 432 from 462 leaves us with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 48

Going ahead to step 5:
48 can be fit into 302 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 596.0
The remainder is 14 after subtracting 288 from 302.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 48

Going ahead to step 6:
The number 48 fits into 141 2 times, leaving a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 5962.0
Deduct 96 from 141 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 48 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 5962.9
If we subtract 432 from 450, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 48 fits into 180 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 5962.93
If we subtract 144 from 180, 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.

Moving on to step 9:
360 divided by 48 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 5962.937
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
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: 5962.9375
Deduct 240 from 240 and we're left 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 11:
48 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5962.9375
The remainder is 0 after subtracting 0 from 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 12:
0 divided by 48 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5962.9375
Deduct 0 from 0 and we're left 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 result is 5962.9375 with a remainder of 0.0.
