We're dividing 593868 by 39 
The aim is to understand the frequency of 39 in 593868.

Moving on to step 1:
39 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 39

Moving on to step 2:
59 divided by 39 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 39 from 59.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 39

Moving on to step 3:
39 can be fit into 203 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 195 from 203, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 39

Going ahead to step 4:
When dividing 88 by 39, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 152.0
Deduct 78 from 88 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 39

Going ahead to step 5:
If we divide 106 by 39, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1522.0
Subtracting 78 from 106 leaves us with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 39

Advancing to step 6:
39 can be fit into 288 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 15227.0
Subtracting 273 from 288 leaves us 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.

Advancing to step 7:
If we divide 150 by 39, we get 3 and a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 15227.3
Subtracting 117 from 150 leaves us 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 8:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 15227.38
If we take 312 away from 330, we end up 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.

Let's proceed to step 9:
If we divide 180 by 39, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 15227.384
If we subtract 156 from 180, we 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.

Let's proceed to step 10:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 15227.3846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
When dividing 60 by 39, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 15227.38461
The remainder is 21 after subtracting 39 from 60.
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 12:
39 goes into 210 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15227.384615
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 13:
When dividing 150 by 39, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 15227.3846153
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.

Moving on to step 14:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 15227.38461538
If we take 312 away from 330, we end up 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.

The final outcome is 15227.38461538, with a leftover of 1.8e-08.
