Let's divide 297991 by 48
The aim is to understand the frequency of 48 in 297991.

On to step 1:
48 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 48

On to step 2:
48 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 48

Step 3:
48 goes into 297 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 9 after subtracting 288 from 297.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 48

Moving on to step 4:
48 can be fit into 99 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we take 96 away from 99, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 48

Advancing to step 5:
39 divided by 48 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 620.0
If we subtract 0 from 39, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 48

On to step 6:
If we divide 391 by 48, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 6208.0
Deduct 384 from 391 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 48, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 6208.1
If we subtract 48 from 70, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
48 can be fit into 220 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 6208.14
The remainder is 28 after subtracting 192 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
If we divide 280 by 48, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 6208.145
Subtracting 240 from 280 leaves us 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.

Moving on to step 10:
The number 48 fits into 400 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 6208.1458
If we take 384 away from 400, we end up 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.

Step 11:
If we divide 160 by 48, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 6208.14583
If we subtract 144 from 160, we get 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 12:
48 goes into 160 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 6208.145833
If we take 144 away from 160, we end up 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 6208.145833 and a remainder of 1.6e-06.
