Let's divide 126540 by 49
The aim is to understand the frequency of 49 in 126540.

On to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 49

Moving on to step 2:
49 can be fit into 12 0 times, resulting in 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.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 49

Going ahead to step 3:
The number 49 fits into 126 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 98 from 126, we get 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 49

Let's proceed to step 4:
49 can be fit into 285 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 245 from 285, we get 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 49

Moving on to step 5:
The number 49 fits into 404 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
If we take 392 away from 404, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 49

Let's proceed to step 6:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2582.0
If we take 98 away from 120, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
49 can be fit into 220 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 2582.4
If we subtract 196 from 220, 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.

On to step 8:
If we divide 240 by 49, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 2582.44
Subtract 196 from 240 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.

The final result is 2582.44 with a remainder of 0.044.
