574137 ÷ 39 
The aim is to understand the frequency of 39 in 574137.

Moving on to step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 39

Step 2:
The number 39 fits into 57 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 39 from 57, we get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 39

Going ahead to step 3:
39 goes into 184 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 156 from 184, we get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 39

Advancing to step 4:
281 divided by 39 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtracting 273 from 281 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Going ahead to step 5:
39 can be fit into 83 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 1472.0
Subtracting 78 from 83 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 39

Advancing to step 6:
If we divide 57 by 39, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 14721.0
Deduct 39 from 57 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 39, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 14721.4
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 39, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 14721.46
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 39, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 14721.461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 14721.4615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
150 divided by 39 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 14721.46153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
39 goes into 330 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 14721.461538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
39 goes into 180 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14721.4615384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 39 fits into 240 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 14721.46153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 14721.46153846 with a remainder of 6e-09.
