Let's divide 75572 by 49
The aim is to understand the frequency of 49 in 75572.

Going ahead to step 1:
The number 49 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 49

Advancing to step 2:
If we divide 75 by 49, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 26 after subtracting 49 from 75.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 49

Advancing to step 3:
The number 49 fits into 265 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 245 from 265 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 49

Let's proceed to step 4:
49 goes into 207 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Deduct 196 from 207 and we're left with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 49

On to step 5:
The number 49 fits into 112 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1542.0
If we take 98 away from 112, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 6:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 1542.2
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
49 can be fit into 420 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1542.28
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
The number 49 fits into 280 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1542.285
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
350 divided by 49 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1542.2857
The remainder is 7 after subtracting 343 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
49 goes into 70 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1542.28571
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
49 goes into 210 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1542.285714
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
If we divide 140 by 49, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 1542.2857142
If we subtract 98 from 140, we get 42.
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 13:
420 divided by 49 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1542.28571428
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 1542.28571428 with a remaining 2.8e-08.
