800591 divided by 39 
The aim is to understand the frequency of 39 in 800591.

Let's proceed to step 1:
39 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 39

On to step 2:
If we divide 80 by 39, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 2 after subtracting 78 from 80.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 39

Moving on to step 3:
20 divided by 39 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 39

Step 4:
205 divided by 39 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Deduct 195 from 205 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 39

Let's proceed to step 5:
109 divided by 39 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 2052.0
The remainder is 31 after subtracting 78 from 109.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 39

Going ahead to step 6:
When dividing 311 by 39, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 20527.0
If we take 273 away from 311, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
If we divide 380 by 39, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 20527.9
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
39 can be fit into 290 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 20527.97
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 20527.974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
39 goes into 140 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 20527.9743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
If we divide 230 by 39, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 20527.97435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 20527.974358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
380 divided by 39 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 20527.9743589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
39 goes into 290 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 20527.97435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 20527.97435897 with a remaining 1.7e-08.
