Let's divide 3689999 by 104
The aim is to understand the frequency of 104 in 3689999.

Going ahead to step 1:
If we divide 3 by 104, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 104

Advancing to step 2:
104 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 104

Moving on to step 3:
368 divided by 104 is 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 312 from 368 to get 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 104

On to step 4:
569 divided by 104 is 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 520 from 569 to get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 104

Step 5:
499 divided by 104 is 4 with a remainder of 83.
The next digit of our result is 4. 
Result so far: 354.0
Subtract 416 from 499 to get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 104

Moving on to step 6:
If we divide 839 by 104, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 3548.0
Subtract 832 from 839 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 104

Advancing to step 7:
The number 104 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 35480.0
If we subtract 0 from 79, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 8:
104 goes into 790 7 times with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 35480.7
Deduct 728 from 790 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
If we divide 620 by 104, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 35480.75
Deduct 520 from 620 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
1000 divided by 104 is 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 35480.759
Subtracting 936 from 1000 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
104 goes into 640 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 35480.7596
Deduct 624 from 640 and we're left with 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 12:
The number 104 fits into 160 1 times, leaving a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 35480.75961
Deduct 104 from 160 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
The number 104 fits into 560 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 35480.759615
Subtract 520 from 560 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
The number 104 fits into 400 3 times, leaving a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 35480.7596153
Subtracting 312 from 400 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 15:
880 divided by 104 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 35480.75961538
Subtracting 832 from 880 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 35480.75961538 with a remainder of 4.8e-08.
