We divide 535848 by 39
The aim is to understand the frequency of 39 in 535848.

On to step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 39

On to step 2:
If we divide 53 by 39, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 39 from 53 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 39

On to step 3:
The number 39 fits into 145 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 117 away from 145, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 39

Let's proceed to step 4:
The number 39 fits into 288 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 137.0
If we take 273 away from 288, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 39

Advancing to step 5:
If we divide 154 by 39, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1373.0
If we subtract 117 from 154, we get 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 39

Advancing to step 6:
378 divided by 39 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 13739.0
If we take 351 away from 378, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 39, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 13739.6
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 13739.69
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 39, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 13739.692
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 39, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13739.6923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13739.6923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
39 goes into 300 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13739.692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
If we divide 270 by 39, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 13739.6923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 13739.69230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 13739.69230769 with a remaining 9e-09.
