Let's divide 133942 by 39
The aim is to understand the frequency of 39 in 133942.

Let's proceed to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 39

Step 2:
39 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 39

Let's proceed to step 3:
133 divided by 39 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 117 away from 133, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 39

Moving on to step 4:
169 divided by 39 is 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 156 from 169, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 39

Going ahead to step 5:
39 can be fit into 134 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 343.0
Deduct 117 from 134 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 39

Let's proceed to step 6:
When dividing 172 by 39, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3434.0
If we subtract 156 from 172, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
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: 3434.4
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 39, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 3434.41
If we take 39 away from 40, we end up 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.

Moving on to step 9:
When dividing 10 by 39, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3434.41
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
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: 3434.4102
If we take 78 away from 100, we end up 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.

Advancing to step 11:
If we divide 220 by 39, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3434.41025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3434.410256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 39, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3434.4102564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
39 goes into 40 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3434.41025641
Subtracting 39 from 40 leaves us 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.

Our division results in 3434.41025641 with a remaining 1e-09.
