We look at the division of 722720 by 49 
The aim is to understand the frequency of 49 in 722720.

Let's proceed to step 1:
The number 49 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 49

Going ahead to step 2:
49 goes into 72 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 49 from 72 and we're left with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 49

Going ahead to step 3:
When dividing 232 by 49, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 36 after subtracting 196 from 232.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 49

Moving on to step 4:
49 can be fit into 367 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 147.0
Deduct 343 from 367 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 49

Going ahead to step 5:
49 goes into 242 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 1474.0
If we subtract 196 from 242, we get 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 49

Let's proceed to step 6:
49 can be fit into 460 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 14749.0
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 49, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 14749.3
The remainder is 43 after subtracting 147 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
If we divide 430 by 49, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 14749.38
The remainder is 38 after subtracting 392 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 49 fits into 380 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 14749.387
If we take 343 away from 380, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
370 divided by 49 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 14749.3877
Subtract 343 from 370 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 14749.3877 with a remaining 0.00027.
