We divide 288913 by 39
The aim is to understand the frequency of 39 in 288913.

On to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 39

On to step 2:
39 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 39

Moving on to step 3:
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: 7.0
If we subtract 273 from 288, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 39

Going ahead to step 4:
39 can be fit into 159 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we take 156 away from 159, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 39

Let's proceed to step 5:
When dividing 31 by 39, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 740.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 39

On to step 6:
39 can be fit into 313 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 7408.0
Deduct 312 from 313 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7408.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 7408.02
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
When dividing 220 by 39, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 7408.025
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
If we divide 250 by 39, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 7408.0256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 7408.02564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
39 goes into 40 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 7408.025641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
When dividing 10 by 39, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7408.025641
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
39 goes into 100 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 7408.02564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 7408.02564102, with a leftover of 2.2e-08.
