494383 ÷ 39 
The aim is to understand the frequency of 39 in 494383.

Going ahead to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 39

Step 2:
39 can be fit into 49 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 49 leaves us with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 39

Advancing to step 3:
104 divided by 39 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 78 away from 104, we end up with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 39

Going ahead to step 4:
39 goes into 263 6 times with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 234 from 263 and we're left with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 39

Let's proceed to step 5:
The number 39 fits into 298 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 1267.0
If we take 273 away from 298, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 39

Going ahead to step 6:
The number 39 fits into 253 6 times, leaving a remainder of 19.
The next digit of our result is 6. 
Result so far: 12676.0
Deduct 234 from 253 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.

Moving on to step 7:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 12676.4
If we take 156 away from 190, we end up 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.

Step 8:
If we divide 340 by 39, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 12676.48
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.

Moving on to 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: 12676.487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
39 can be fit into 70 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 12676.4871
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.

On to step 11:
If we divide 310 by 39, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 12676.48717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
When dividing 370 by 39, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 12676.487179
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.

Let's proceed to step 13:
190 divided by 39 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 12676.4871794
If we take 156 away from 190, we end up 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 14:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 12676.48717948
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 final outcome is 12676.48717948, with a leftover of 2.8e-08.
