Let's divide 77213108 by 104
The aim is to understand the frequency of 104 in 77213108.

Step 1:
If we divide 7 by 104, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 104

Going ahead to step 2:
104 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 104

Advancing to step 3:
104 goes into 772 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 728 from 772 and we're left with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 104

Step 4:
104 can be fit into 441 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 416 from 441 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 104

On to step 5:
If we divide 253 by 104, we get 2 and a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 742.0
If we subtract 208 from 253, we get 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 104

Moving on to step 6:
451 divided by 104 is 4 with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 7424.0
Subtract 416 from 451 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 104

Advancing to step 7:
350 divided by 104 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 74243.0
If we subtract 312 from 350, we get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 104

Step 8:
The number 104 fits into 388 3 times, leaving a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 742433.0
Subtracting 312 from 388 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
104 goes into 760 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 742433.7
Subtract 728 from 760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 104, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 742433.73
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 104 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 742433.73
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 104 fits into 800 7 times, leaving a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 742433.7307
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
If we divide 720 by 104, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 742433.73076
If we take 624 away from 720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
The number 104 fits into 960 9 times, leaving a remainder of 24.
The next digit of our result is 9. 
Result so far: 742433.730769
If we take 936 away from 960, we end up 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.

Let's proceed to step 15:
240 divided by 104 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 742433.7307692
Subtract 208 from 240 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
The number 104 fits into 320 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 742433.73076923
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 742433.73076923, with a leftover of 8e-09.
