We divide 358529 by 39
The aim is to understand the frequency of 39 in 358529.

Moving on to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 39

Moving on to step 2:
The number 39 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 39

Step 3:
39 can be fit into 358 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 351 from 358 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 39

On to step 4:
39 goes into 75 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 39 from 75, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 39

Moving on to step 5:
362 divided by 39 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 919.0
Deduct 351 from 362 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 39

Going ahead to step 6:
119 divided by 39 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 9193.0
Deduct 117 from 119 and we're left with 2.
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 7:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9193.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
39 can be fit into 200 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 9193.05
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.

Advancing to step 9:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 9193.051
If we take 39 away from 50, we end up 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 can be fit into 110 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 9193.0512
The remainder is 32 after subtracting 78 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
The number 39 fits into 320 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 9193.05128
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
39 goes into 80 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 9193.051282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
39 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9193.051282
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.

Moving on to step 14:
39 goes into 200 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9193.05128205
Deduct 195 from 200 and we're left 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.

The final outcome is 9193.05128205, with a leftover of 5e-09.
