We look at the division of 685552 by 49 
The aim is to understand the frequency of 49 in 685552.

Step 1:
6 divided by 49 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 49

Step 2:
49 goes into 68 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 49 away from 68, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 49

Let's proceed to step 3:
When dividing 195 by 49, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 147 from 195 and we're left with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 49

Step 4:
If we divide 485 by 49, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 441 from 485, we get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 49

Advancing to step 5:
The number 49 fits into 445 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1399.0
If we take 441 away from 445, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 49

Let's proceed to step 6:
When dividing 42 by 49, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 13990.0
If we subtract 0 from 42, 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.

Moving on to step 7:
The number 49 fits into 420 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 13990.8
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.

Going ahead to step 8:
When dividing 280 by 49, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13990.85
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:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 13990.857
If we take 343 away from 350, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 13990.8571
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.

On to step 11:
The number 49 fits into 210 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 13990.85714
If we take 196 away from 210, 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.

On to step 12:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 13990.857142
Subtract 98 from 140 to 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.

Advancing 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: 13990.8571428
If we subtract 392 from 420, we 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.

Moving on to step 14:
The number 49 fits into 280 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 13990.85714285
If we take 245 away from 280, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 13990.85714285 with a remaining 3.5e-08.
