We divide 646148 by 49
The aim is to understand the frequency of 49 in 646148.

Let's proceed to step 1:
49 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 49

On to step 2:
When dividing 64 by 49, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 49 away from 64, we end up with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 49

On to step 3:
When dividing 156 by 49, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 9 after subtracting 147 from 156.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 49

On to step 4:
91 divided by 49 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 49 from 91 to get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 49

On to step 5:
The number 49 fits into 424 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1318.0
If we subtract 392 from 424, we get 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 49

On to step 6:
49 can be fit into 328 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 13186.0
Deduct 294 from 328 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
When dividing 340 by 49, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 13186.6
The remainder is 46 after subtracting 294 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
460 divided by 49 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 13186.69
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
49 goes into 190 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 13186.693
Subtracting 147 from 190 leaves us 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.

Step 10:
When dividing 430 by 49, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 13186.6938
Subtract 392 from 430 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
The number 49 fits into 380 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 13186.69387
If we take 343 away from 380, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
If we divide 370 by 49, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 13186.693877
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.

The final result is 13186.693877 with a remainder of 2.7e-06.
