We look at the division of 534319 by 39 
The aim is to understand the frequency of 39 in 534319.

Advancing to step 1:
39 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 39

Moving on to step 2:
39 goes into 53 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 14 after subtracting 39 from 53.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 39

On to step 3:
144 divided by 39 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 117 away from 144, we end up with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 39

On to step 4:
The number 39 fits into 273 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we subtract 273 from 273, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 39

Going ahead to step 5:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1370.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 39

Going ahead to step 6:
19 divided by 39 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 13700.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 13700.4
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 39 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 13700.48
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
If we divide 280 by 39, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 13700.487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 13700.4871
If we subtract 39 from 70, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13700.48717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
If we divide 370 by 39, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 13700.487179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 13700.4871794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
The number 39 fits into 340 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 13700.48717948
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 13700.48717948, and the remainder is 2.8e-08.
