Let's divide 13536421 by 796
The aim is to understand the frequency of 796 in 13536421.

Going ahead to step 1:
796 goes into 1 0 times 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.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 796

Advancing to step 2:
796 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 796

Going ahead to step 3:
796 can be fit into 135 0 times, resulting in a remainder of 135.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 135 after subtracting 0 from 135.
Include the next digit (3) from the dividend after 135, then repeat: 1353 / 796

Moving on to step 4:
When dividing 1353 by 796, we get 1 with a remainder of 557.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 557 after subtracting 796 from 1353.
Append the next digit (6) from the dividend to 557 and continue with: 5576 / 796

Going ahead to step 5:
The number 796 fits into 5576 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 5572 from 5576 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 796

On to step 6:
When dividing 44 by 796, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtract 0 from 44 to get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 796

Moving on to step 7:
If we divide 442 by 796, we get 0 and a remainder of 442.
Use 0 as the next digit of our solution. 
Result so far: 1700.0
Subtracting 0 from 442 leaves us with 442.
Take the next digit (1) from the dividend and append it to 442, then repeat: 4421 / 796

Moving on to step 8:
The number 796 fits into 4421 5 times, leaving a remainder of 441.
Record the quotient 5 as the next digit in the result. 
Result so far: 17005.0
If we take 3980 away from 4421, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

On to step 9:
4410 divided by 796 is 5 with a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 17005.5
If we take 3980 away from 4410, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 10:
The number 796 fits into 4300 5 times, leaving a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 17005.55
Subtracting 3980 from 4300 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 17005.55 with a remainder of 0.32.
