We're dividing 21627 by 39 
The aim is to understand the frequency of 39 in 21627.

On to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 39

Advancing to step 2:
If we divide 21 by 39, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 39

Let's proceed to step 3:
39 goes into 216 5 times with a remainder of 21.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 21 after subtracting 195 from 216.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 39

Going ahead to step 4:
The number 39 fits into 212 5 times, leaving a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 195 from 212 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 39

Moving on to step 5:
39 goes into 177 4 times with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 554.0
The remainder is 21 after subtracting 156 from 177.
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 6:
39 can be fit into 210 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 554.5
Subtracting 195 from 210 leaves us 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.

Let's proceed to step 7:
When dividing 150 by 39, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 554.53
Subtracting 117 from 150 leaves us 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 8:
When dividing 330 by 39, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 554.538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
39 goes into 180 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 554.5384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 39 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 554.53846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 39 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 554.538461
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.

Going ahead to step 12:
210 divided by 39 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 554.5384615
If we subtract 195 from 210, we 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.

Going ahead to step 13:
When dividing 150 by 39, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 554.53846153
Subtracting 117 from 150 leaves us 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.

The quotient of the division is 554.53846153, and the remainder is 3.3e-08.
