3688863 divided by 728 
The aim is to understand the frequency of 728 in 3688863.

Advancing to step 1:
728 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 728

Let's proceed to step 2:
When dividing 36 by 728, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 728

Moving on to step 3:
728 can be fit into 368 0 times, resulting in a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 368 to get 368.
Fetch the next digit (8) from the dividend, attach it to 368 and continue: 3688 / 728

Moving on to step 4:
728 goes into 3688 5 times with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 48 after subtracting 3640 from 3688.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 728

Advancing to step 5:
728 can be fit into 488 0 times, resulting in a remainder of 488.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 488 after subtracting 0 from 488.
Fetch the next digit (6) from the dividend, attach it to 488 and continue: 4886 / 728

Let's proceed to step 6:
When dividing 4886 by 728, we get 6 with a remainder of 518.
Write down 6 as next digit of the result. 
Result so far: 506.0
The remainder is 518 after subtracting 4368 from 4886.
Include the next digit (3) from the dividend after 518, then repeat: 5183 / 728

Advancing to step 7:
728 can be fit into 5183 7 times, resulting in a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 5067.0
Subtracting 5096 from 5183 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 8:
728 can be fit into 870 1 times, resulting in a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 5067.1
Subtracting 728 from 870 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
728 goes into 1420 1 times with a remainder of 692.
The number 1 becomes the next digit in our result. 
Result so far: 5067.11
If we take 728 away from 1420, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

The quotient of the division is 5067.11, and the remainder is 0.692.
