We look at the division of 588633 by 39 
The aim is to understand the frequency of 39 in 588633.

On to step 1:
The number 39 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 39

Going ahead to step 2:
39 can be fit into 58 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 39 from 58 leaves us with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 39

Advancing to step 3:
198 divided by 39 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 3 after subtracting 195 from 198.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 39

Going ahead to step 4:
39 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we subtract 0 from 36, we get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 39

On to step 5:
If we divide 363 by 39, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 1509.0
Subtract 351 from 363 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 39

Moving on to step 6:
39 can be fit into 123 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 15093.0
The remainder is 6 after subtracting 117 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 39 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 15093.1
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15093.15
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 39, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 15093.153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 15093.1538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15093.15384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 39, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 15093.153846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 15093.1538461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
210 divided by 39 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15093.15384615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 15093.15384615 and a remainder of 1.5e-08.
