1255 ÷ 49 
The aim is to understand the frequency of 49 in 1255.

Advancing to step 1:
49 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 49

Advancing to step 2:
The number 49 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 49

Moving on to step 3:
The number 49 fits into 125 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 98 from 125 leaves us with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 49

On to step 4:
49 goes into 275 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 245 from 275, we 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.

Moving on to step 5:
49 goes into 300 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 25.6
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
If we divide 60 by 49, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 25.61
Subtracting 49 from 60 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 49 fits into 110 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 25.612
If we subtract 98 from 110, we get 12.
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:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 25.6122
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 25.6122, and the remainder is 0.00022.
