We're dividing 81458593 by 39 
The aim is to understand the frequency of 39 in 81458593.

Moving on to step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 39

Going ahead to step 2:
39 can be fit into 81 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 78 from 81 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 39

Going ahead to step 3:
39 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 34, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 39

Step 4:
39 can be fit into 345 8 times, resulting in a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 312 from 345 to get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 39

Moving on to step 5:
When dividing 338 by 39, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 2088.0
If we subtract 312 from 338, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 39

Advancing to step 6:
39 goes into 265 6 times with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 20886.0
If we subtract 234 from 265, we get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 39

Moving on to step 7:
39 goes into 319 8 times with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 208868.0
If we take 312 away from 319, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 39

Let's proceed to step 8:
If we divide 73 by 39, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 2088681.0
If we subtract 39 from 73, 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.

Going ahead to step 9:
340 divided by 39 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 2088681.8
If we take 312 away from 340, we end up with 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 10:
39 goes into 280 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 2088681.87
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
70 divided by 39 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 2088681.871
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.

Step 12:
39 goes into 310 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 2088681.8717
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.

Step 13:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 2088681.87179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 2088681.871794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 15:
340 divided by 39 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 2088681.8717948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 2088681.87179487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 2088681.87179487 with a remainder of 7e-09.
