We divide 669904 by 49
The aim is to understand the frequency of 49 in 669904.

Let's proceed to step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 49

Advancing to step 2:
If we divide 66 by 49, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 17 after subtracting 49 from 66.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 49

Step 3:
49 can be fit into 179 3 times, resulting in a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 147 from 179 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 49

On to step 4:
When dividing 329 by 49, we get 6 with a remainder of 35.
The next digit of our result is 6. 
Result so far: 136.0
If we subtract 294 from 329, we get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 49

Going ahead to step 5:
49 goes into 350 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1367.0
Subtracting 343 from 350 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 49

Step 6:
The number 49 fits into 74 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 13671.0
Deduct 49 from 74 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 49, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13671.5
If we subtract 245 from 250, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 49 fits into 50 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 13671.51
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
49 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13671.51
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 49, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 13671.5102
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
If we divide 20 by 49, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13671.5102
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 49 fits into 200 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 13671.510204
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
49 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 13671.510204
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
49 goes into 400 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 13671.51020408
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 13671.51020408 and a remainder of 8e-09.
