We divide 839572 by 39
The aim is to understand the frequency of 39 in 839572.

Going ahead to step 1:
8 divided by 39 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Step 2:
If we divide 83 by 39, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 78 from 83 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 39

Moving on to step 3:
59 divided by 39 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 39 from 59, we get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 39

Moving on to step 4:
When dividing 205 by 39, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtract 195 from 205 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 39

Step 5:
107 divided by 39 is 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2152.0
Deduct 78 from 107 and we're left with 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 39

Let's proceed to step 6:
The number 39 fits into 292 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 21527.0
The remainder is 19 after subtracting 273 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 39 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 21527.4
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
If we divide 340 by 39, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 21527.48
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
39 goes into 280 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 21527.487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
70 divided by 39 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 21527.4871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
310 divided by 39 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 21527.48717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 21527.487179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
When dividing 190 by 39, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 21527.4871794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
When dividing 340 by 39, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 21527.48717948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 21527.48717948 with a remainder of 2.8e-08.
