We look at the division of 702574 by 49 
The aim is to understand the frequency of 49 in 702574.

Let's proceed to step 1:
7 divided by 49 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 49

Advancing to step 2:
When dividing 70 by 49, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 70, we end up with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 49

Let's proceed to step 3:
The number 49 fits into 212 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 196 from 212 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 49

Let's proceed to step 4:
If we divide 165 by 49, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 18 after subtracting 147 from 165.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 49

Let's proceed to step 5:
If we divide 187 by 49, we get 3 and a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 1433.0
Subtract 147 from 187 to get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 49

Moving on to step 6:
49 goes into 404 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 14338.0
The remainder is 12 after subtracting 392 from 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
120 divided by 49 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 14338.2
Deduct 98 from 120 and we're left 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.

Going ahead to step 8:
When dividing 220 by 49, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14338.24
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.

Step 9:
49 goes into 240 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 14338.244
The remainder is 44 after subtracting 196 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 14338.244 and a remainder of 0.0044.
