We look at the division of 49287 by 39 
The aim is to understand the frequency of 39 in 49287.

Step 1:
4 divided by 39 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 39

Moving on to step 2:
If we divide 49 by 39, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 39 from 49 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 39

Let's proceed to step 3:
The number 39 fits into 102 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 24 after subtracting 78 from 102.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 39

Advancing to step 4:
The number 39 fits into 248 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtracting 234 from 248 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 39

Let's proceed to step 5:
The number 39 fits into 147 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1263.0
If we take 117 away from 147, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 6:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1263.7
Subtracting 273 from 300 leaves us 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.

Let's proceed to step 7:
39 goes into 270 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 1263.76
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
If we divide 360 by 39, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1263.769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 1263.7692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1263.76923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1263.76923
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 1263.7692307
If we subtract 273 from 300, we 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.

Advancing to step 13:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1263.76923076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 1263.76923076 with a remaining 3.6e-08.
