We divide 358146 by 15
The aim is to understand the frequency of 15 in 358146.

On to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

Let's proceed to step 2:
The number 15 fits into 35 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 30 from 35 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 15

Step 3:
15 can be fit into 58 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 45 from 58 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 15

Going ahead to step 4:
If we divide 131 by 15, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
If we subtract 120 from 131, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 15

Moving on to step 5:
15 can be fit into 114 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 2387.0
Deduct 105 from 114 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 15

On to step 6:
96 divided by 15 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 23876.0
If we take 90 away from 96, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
15 goes into 60 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 23876.4
Subtracting 60 from 60 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 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23876.4
Deduct 0 from 0 and we're left 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.

Let's proceed to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23876.4
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.

In conclusion, the division gives 23876.4 with a balance of 0.0.
