309371 ÷ 49 
The aim is to understand the frequency of 49 in 309371.

Going ahead to step 1:
3 divided by 49 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 49

Step 2:
The number 49 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 49

Advancing to step 3:
When dividing 309 by 49, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 294 from 309, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 49

Moving on to step 4:
If we divide 153 by 49, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 147 from 153 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 49

Moving on to step 5:
67 divided by 49 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 631.0
If we take 49 away from 67, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 49

Advancing to step 6:
49 can be fit into 181 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 6313.0
Deduct 147 from 181 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.

Going ahead to step 7:
The number 49 fits into 340 6 times, leaving a remainder of 46.
The next digit of our result is 6. 
Result so far: 6313.6
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
460 divided by 49 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6313.69
If we subtract 441 from 460, we get 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 9:
49 goes into 190 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 6313.693
Subtract 147 from 190 to get 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:
430 divided by 49 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 6313.6938
Subtracting 392 from 430 leaves us 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.

Going ahead to step 11:
When dividing 380 by 49, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 6313.69387
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
The number 49 fits into 370 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 6313.693877
Subtract 343 from 370 to get 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 outcome is 6313.693877, with a leftover of 2.7e-06.
