Let's divide 275661 by 39
The aim is to understand the frequency of 39 in 275661.

Going ahead to step 1:
39 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 39

Moving on to step 2:
The number 39 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 39

Moving on to step 3:
275 divided by 39 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 2 after subtracting 273 from 275.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 39

Let's proceed to step 4:
If we divide 26 by 39, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 39

Going ahead to step 5:
If we divide 266 by 39, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
If we subtract 234 from 266, we get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 39

Going ahead to step 6:
39 goes into 321 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 7068.0
Subtracting 312 from 321 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
90 divided by 39 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 7068.2
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7068.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 39, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7068.23
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 39, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 7068.2307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 7068.23076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 7068.230769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 7068.2307692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 7068.23076923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 7068.23076923, with a leftover of 3e-09.
