Let's divide 735801 by 15
The aim is to understand the frequency of 15 in 735801.

Let's proceed to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 15

Let's proceed to step 2:
15 can be fit into 73 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
If we take 60 away from 73, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Advancing to step 3:
15 can be fit into 135 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 135 from 135 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Step 4:
If we divide 8 by 15, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 15

On to step 5:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4905.0
Subtracting 75 from 80 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 15

Moving on to step 6:
15 can be fit into 51 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 49053.0
If we subtract 45 from 51, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 15 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 49053.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49053.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49053.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 49053.4 with a remaining 0.0.
