Let's divide 13694426 by 864
The aim is to understand the frequency of 864 in 13694426.

Step 1:
When dividing 1 by 864, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 864

On to step 2:
When dividing 13 by 864, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 864

On to step 3:
864 can be fit into 136 0 times, resulting in a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Grab the next digit (9) from the dividend, add it to 136, then carry on: 1369 / 864

Let's proceed to step 4:
When dividing 1369 by 864, we get 1 with a remainder of 505.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 864 from 1369 leaves us with 505.
Bring next digit (4) of the dividend behind the 505 and repeat the process: 5054 / 864

Going ahead to step 5:
If we divide 5054 by 864, we get 5 and a remainder of 734.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 4320 from 5054, we get 734.
Bring next digit (4) of the dividend behind the 734 and repeat the process: 7344 / 864

Going ahead to step 6:
If we divide 7344 by 864, we get 8 and a remainder of 432.
The next digit of our result is 8. 
Result so far: 158.0
Subtract 6912 from 7344 to get 432.
Take the next digit (2) from the dividend and append it to 432, then repeat: 4322 / 864

Let's proceed to step 7:
864 can be fit into 4322 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1585.0
The remainder is 2 after subtracting 4320 from 4322.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 864

Moving on to step 8:
864 can be fit into 26 0 times, resulting in a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 15850.0
The remainder is 26 after subtracting 0 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
864 can be fit into 260 0 times, resulting in a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 15850.0
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
If we divide 2600 by 864, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 15850.03
Subtracting 2592 from 2600 leaves us 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.

Moving on to step 11:
When dividing 80 by 864, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 15850.03
The remainder is 80 after subtracting 0 from 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:
864 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 15850.03
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 15850.03, with a leftover of 0.008.
