626650 ÷ 49 
The aim is to understand the frequency of 49 in 626650.

Step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 49

On to step 2:
The number 49 fits into 62 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 49 from 62 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 49

Advancing to step 3:
136 divided by 49 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 98 from 136, we get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 49

Let's proceed to step 4:
The number 49 fits into 386 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 343 away from 386, we end up with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 49

Step 5:
When dividing 435 by 49, we get 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 1278.0
Subtracting 392 from 435 leaves us with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 49

Going ahead to step 6:
49 can be fit into 430 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 12788.0
Deduct 392 from 430 and we're left with 38.
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 7:
49 can be fit into 380 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 12788.7
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
49 can be fit into 370 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 12788.77
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 12788.77 with a remainder of 0.027.
