Let's divide 678923 by 49
The aim is to understand the frequency of 49 in 678923.

Advancing to step 1:
6 divided by 49 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 49

Going ahead to step 2:
67 divided by 49 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 49 away from 67, we end up with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 49

Moving on to step 3:
When dividing 188 by 49, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 147 from 188 to get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 49

Advancing to step 4:
If we divide 419 by 49, we get 8 and a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 392 from 419 to get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 49

Step 5:
If we divide 272 by 49, we get 5 and a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
Subtract 245 from 272 to get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 49

On to step 6:
273 divided by 49 is 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 13855.0
The remainder is 28 after subtracting 245 from 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
The number 49 fits into 280 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 13855.5
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
If we divide 350 by 49, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 13855.57
Subtract 343 from 350 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
The number 49 fits into 70 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 13855.571
Deduct 49 from 70 and we're left with 21.
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 10:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 13855.5714
Subtracting 196 from 210 leaves us 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.

Going ahead to step 11:
140 divided by 49 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 13855.57142
If we take 98 away from 140, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
420 divided by 49 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 13855.571428
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.

Moving on to step 13:
The number 49 fits into 280 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13855.5714285
If we subtract 245 from 280, we 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 14:
49 goes into 350 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 13855.57142857
Subtract 343 from 350 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 13855.57142857 with a remainder of 7e-09.
