We look at the division of 84380 by 39 
The aim is to understand the frequency of 39 in 84380.

On to step 1:
The number 39 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 39

Let's proceed to step 2:
When dividing 84 by 39, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 78 from 84, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 39

Advancing to step 3:
39 can be fit into 63 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 39 away from 63, we end up with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 39

Moving on to step 4:
If we divide 248 by 39, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 216.0
If we subtract 234 from 248, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 39

On to step 5:
140 divided by 39 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 2163.0
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 6:
39 goes into 230 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2163.5
If we subtract 195 from 230, we 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.

Advancing to step 7:
If we divide 350 by 39, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2163.58
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 8:
380 divided by 39 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 2163.589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
39 goes into 290 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 2163.5897
If we take 273 away from 290, we end up with 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 10:
170 divided by 39 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2163.58974
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
When dividing 140 by 39, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 2163.589743
Subtract 117 from 140 to 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.

Step 12:
39 can be fit into 230 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2163.5897435
If we subtract 195 from 230, we 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.

Step 13:
350 divided by 39 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 2163.58974358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 2163.58974358 and a remainder of 3.8e-08.
