318620 ÷ 39 
The aim is to understand the frequency of 39 in 318620.

Advancing to step 1:
3 divided by 39 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 39

Let's proceed to step 2:
The number 39 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 39

Step 3:
318 divided by 39 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 6 after subtracting 312 from 318.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 39

On to step 4:
66 divided by 39 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 39 away from 66, we end up with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 39

Moving on to step 5:
272 divided by 39 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 816.0
If we take 234 away from 272, we end up with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 39

Step 6:
39 goes into 380 9 times with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 8169.0
Subtract 351 from 380 to 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.

Going ahead to step 7:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 8169.7
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.

Going ahead to step 8:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 8169.74
If we subtract 156 from 170, we 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 9:
39 goes into 140 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 8169.743
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.

Going ahead to step 10:
If we divide 230 by 39, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8169.7435
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.

Advancing to step 11:
When dividing 350 by 39, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8169.74358
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.

Moving on to step 12:
If we divide 380 by 39, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 8169.743589
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.

Step 13:
39 goes into 290 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 8169.7435897
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 14:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 8169.74358974
Subtracting 156 from 170 leaves us 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.

After the division, we end up with 8169.74358974 and a remainder of 1.4e-08.
