We're dividing 668354 by 49 
The aim is to understand the frequency of 49 in 668354.

Step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 49

On to step 2:
66 divided by 49 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 49 from 66.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 49

Moving on to step 3:
If we divide 178 by 49, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 147 from 178 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 49

Let's proceed to step 4:
The number 49 fits into 313 6 times, leaving a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtracting 294 from 313 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 49

Going ahead to step 5:
195 divided by 49 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1363.0
The remainder is 48 after subtracting 147 from 195.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 49

Going ahead to step 6:
49 goes into 484 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 13639.0
If we take 441 away from 484, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
430 divided by 49 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 13639.8
If we take 392 away from 430, we end up 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.

Step 8:
380 divided by 49 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 13639.87
If we subtract 343 from 380, we get 37.
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 9:
370 divided by 49 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 13639.877
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.

In conclusion, the division gives 13639.877 with a balance of 0.0027.
