590052 ÷ 39 
The aim is to understand the frequency of 39 in 590052.

Let's proceed to step 1:
5 divided by 39 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 39

On to step 2:
If we divide 59 by 39, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 39 from 59, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 39

Step 3:
The number 39 fits into 200 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 195 from 200 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 39

Moving on to step 4:
50 divided by 39 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 151.0
Subtracting 39 from 50 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 39

Moving on to step 5:
The number 39 fits into 115 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 1512.0
The remainder is 37 after subtracting 78 from 115.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 39

Advancing to step 6:
If we divide 372 by 39, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 15129.0
If we take 351 away from 372, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 39, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15129.5
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
If we divide 150 by 39, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 15129.53
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
If we divide 330 by 39, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 15129.538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15129.5384
Subtract 156 from 180 to get 24.
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 11:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 15129.53846
Subtracting 234 from 240 leaves us 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.

Step 12:
39 goes into 60 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 15129.538461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
When dividing 210 by 39, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15129.5384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
39 goes into 150 3 times with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 15129.53846153
Deduct 117 from 150 and we're left 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.

Our division results in 15129.53846153 with a remaining 3.3e-08.
