300212 divided by 39 
The aim is to understand the frequency of 39 in 300212.

Advancing 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
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 39

Advancing to step 2:
If we divide 30 by 39, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 39

Going ahead to step 3:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
If we take 273 away from 300, we end up with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 39

Moving on to step 4:
The number 39 fits into 272 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
The remainder is 38 after subtracting 234 from 272.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 39

Advancing to step 5:
When dividing 381 by 39, we get 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 769.0
Subtract 351 from 381 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 39

On to step 6:
If we divide 302 by 39, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7697.0
Deduct 273 from 302 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
If we divide 290 by 39, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7697.7
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 7697.74
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 39 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 7697.743
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
If we divide 230 by 39, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7697.7435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 7697.74358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 39, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 7697.743589
Deduct 351 from 380 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7697.7435897
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
When dividing 170 by 39, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 7697.74358974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 7697.74358974 with a balance of 1.4e-08.
