34310236 ÷ 39 
The aim is to understand the frequency of 39 in 34310236.

Moving on to step 1:
3 divided by 39 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 39

Going ahead to step 2:
The number 39 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 39

On to step 3:
If we divide 343 by 39, we get 8 and a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 312 from 343 and we're left with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 39

Let's proceed to step 4:
The number 39 fits into 311 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 273 from 311 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 39

Step 5:
When dividing 380 by 39, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 879.0
Deduct 351 from 380 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 39

Going ahead to step 6:
When dividing 292 by 39, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 8797.0
The remainder is 19 after subtracting 273 from 292.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 39

Step 7:
39 can be fit into 193 4 times, resulting in a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 87974.0
The remainder is 37 after subtracting 156 from 193.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 39

Let's proceed to step 8:
When dividing 376 by 39, we get 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 879749.0
If we take 351 away from 376, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 39, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 879749.6
If we take 234 away from 250, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 39, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 879749.64
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
If we divide 40 by 39, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 879749.641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 879749.641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
If we divide 100 by 39, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 879749.64102
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
When dividing 220 by 39, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 879749.641025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 15:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 879749.6410256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
39 goes into 160 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 879749.64102564
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 879749.64102564 and a remainder of 4e-09.
