Let's divide 199374 by 39
The aim is to understand the frequency of 39 in 199374.

Moving on to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 39

On to step 2:
If we divide 19 by 39, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 39

Going ahead to step 3:
39 can be fit into 199 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 195 from 199, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 39

Advancing to step 4:
If we divide 43 by 39, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 39 from 43 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 39

On to step 5:
39 goes into 47 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 511.0
Deduct 39 from 47 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 39

Advancing to step 6:
84 divided by 39 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 5112.0
The remainder is 6 after subtracting 78 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 5112.1
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
If we divide 210 by 39, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5112.15
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 5112.153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
39 goes into 330 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 5112.1538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 5112.15384
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 5112.153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 39 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 5112.1538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
210 divided by 39 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5112.15384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 5112.15384615, and the remainder is 1.5e-08.
