294101 ÷ 39 
The aim is to understand the frequency of 39 in 294101.

Step 1:
2 divided by 39 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 39

Advancing to step 2:
39 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 39

Moving on to step 3:
294 divided by 39 is 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 21 after subtracting 273 from 294.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 39

Let's proceed to step 4:
If we divide 211 by 39, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 16 after subtracting 195 from 211.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 39

Moving on to step 5:
39 goes into 160 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 754.0
Subtracting 156 from 160 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 39

Step 6:
39 goes into 41 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 7541.0
Subtract 39 from 41 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 39, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 7541.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 39, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7541.05
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 39, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 7541.051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
39 goes into 110 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 7541.0512
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
If we divide 320 by 39, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 7541.05128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 39 fits into 80 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 7541.051282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 39, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7541.051282
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 39, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7541.05128205
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 7541.05128205, with a leftover of 5e-09.
