640084 divided by 49 
The aim is to understand the frequency of 49 in 640084.

Let's proceed to 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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 49

On to step 2:
The number 49 fits into 64 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 49 from 64 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 49

Step 3:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 13.0
If we take 147 away from 150, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 49

On to step 4:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 130.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 49

Moving on to step 5:
The number 49 fits into 308 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1306.0
Subtracting 294 from 308 leaves us with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 49

On to step 6:
The number 49 fits into 144 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 13062.0
Deduct 98 from 144 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
49 goes into 460 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 13062.9
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
When dividing 190 by 49, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 13062.93
Deduct 147 from 190 and we're left 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.

Advancing to step 9:
The number 49 fits into 430 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 13062.938
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.

Advancing to step 10:
If we divide 380 by 49, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 13062.9387
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.

Let's proceed to step 11:
49 goes into 370 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 13062.93877
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 13062.93877 and a remainder of 2.7e-05.
