Let's divide 299409 by 39
The aim is to understand the frequency of 39 in 299409.

Moving on to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 39

Going ahead to step 2:
The number 39 fits into 29 0 times, leaving a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 39

Step 3:
The number 39 fits into 299 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 273 from 299, we get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 39

Step 4:
If we divide 264 by 39, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 30 after subtracting 234 from 264.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 39

On to step 5:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 767.0
The remainder is 27 after subtracting 273 from 300.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 39

On to step 6:
The number 39 fits into 279 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7677.0
If we take 273 away from 279, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 7677.1
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 7677.15
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
When dividing 150 by 39, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 7677.153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
When dividing 330 by 39, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 7677.1538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
If we divide 180 by 39, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7677.15384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 39, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 7677.153846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 39 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 7677.1538461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
39 goes into 210 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7677.15384615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 7677.15384615 with a remainder of 1.5e-08.
