We divide 874043 by 15
The aim is to understand the frequency of 15 in 874043.

Let's proceed to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 15

Step 2:
15 goes into 87 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
If we take 75 away from 87, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 15

Moving on to step 3:
The number 15 fits into 124 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 120 from 124, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

Moving on to step 4:
If we divide 40 by 15, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 582.0
Deduct 30 from 40 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 15

Let's proceed to step 5:
If we divide 104 by 15, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 5826.0
Subtracting 90 from 104 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

Step 6:
When dividing 143 by 15, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 58269.0
If we take 135 away from 143, 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.

Advancing to step 7:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58269.5
Subtract 75 from 80 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 58269.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 58269.533
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 58269.533 with a remaining 0.0005.
