We divide 305839 by 39
The aim is to understand the frequency of 39 in 305839.

Advancing to step 1:
39 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 39

Moving on to step 2:
When dividing 30 by 39, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 39

Let's proceed to step 3:
When dividing 305 by 39, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 32 after subtracting 273 from 305.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 39

Advancing to step 4:
The number 39 fits into 328 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 312 from 328 leaves us with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 39

Advancing to step 5:
39 goes into 163 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Subtracting 156 from 163 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 39

Going ahead to step 6:
39 goes into 79 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 7842.0
If we subtract 78 from 79, we get 1.
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 7:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7842.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 39 fits into 100 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 7842.02
Subtract 78 from 100 to get 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 9:
39 goes into 220 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7842.025
Subtracting 195 from 220 leaves us 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.

Let's proceed to step 10:
39 goes into 250 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7842.0256
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.

On to step 11:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 7842.02564
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.

Let's proceed to step 12:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 7842.025641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
If we divide 10 by 39, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7842.025641
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
39 goes into 100 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 7842.02564102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 7842.02564102 with a remaining 2.2e-08.
