We divide 125104 by 39
The aim is to understand the frequency of 39 in 125104.

Let's proceed to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 39

Let's proceed to step 2:
When dividing 12 by 39, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 39

Advancing to step 3:
The number 39 fits into 125 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 117 from 125 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 39

Going ahead to step 4:
If we divide 81 by 39, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 78 from 81, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

Advancing to step 5:
39 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 320.0
Subtract 0 from 30 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 39

Advancing to step 6:
39 can be fit into 304 7 times, resulting in a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 3207.0
The remainder is 31 after subtracting 273 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 3207.7
Subtracting 273 from 310 leaves us 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.

Going ahead to step 8:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 3207.79
Deduct 351 from 370 and we're left 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.

Moving on to step 9:
When dividing 190 by 39, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 3207.794
If we subtract 156 from 190, we get 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 10:
340 divided by 39 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3207.7948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
39 goes into 280 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 3207.79487
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
70 divided by 39 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 3207.794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 3207.7948717
Subtract 273 from 310 to 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.

Step 14:
If we divide 370 by 39, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 3207.79487179
Deduct 351 from 370 and we're left 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.

In conclusion, the division gives 3207.79487179 with a balance of 1.9e-08.
