104083 ÷ 39 
The aim is to understand the frequency of 39 in 104083.

Moving on to step 1:
1 divided by 39 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 39

Advancing to step 2:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 39

Moving on to step 3:
When dividing 104 by 39, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 78 from 104 and we're left with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 39

On to step 4:
260 divided by 39 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 234 from 260 and we're left with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 39

Advancing to step 5:
268 divided by 39 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 266.0
Deduct 234 from 268 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 39

Let's proceed to step 6:
When dividing 343 by 39, we get 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 2668.0
If we subtract 312 from 343, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
If we divide 310 by 39, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 2668.7
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 2668.79
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 39, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 2668.794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 2668.7948
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 2668.79487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
If we divide 70 by 39, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 2668.794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 2668.7948717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
370 divided by 39 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 2668.79487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 2668.79487179 with a remaining 1.9e-08.
