We divide 46843429 by 15
The aim is to understand the frequency of 15 in 46843429.

Step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 15

Step 2:
46 divided by 15 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 45 from 46, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 15

Going ahead to step 3:
When dividing 18 by 15, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 15 away from 18, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 15

Going ahead to step 4:
When dividing 34 by 15, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
If we subtract 30 from 34, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 15

Let's proceed to step 5:
The number 15 fits into 43 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 3122.0
Subtracting 30 from 43 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 15

Step 6:
134 divided by 15 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 31228.0
Deduct 120 from 134 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 15

Step 7:
15 can be fit into 142 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 312289.0
If we subtract 135 from 142, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 15

Going ahead to step 8:
15 goes into 79 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 3122895.0
If we take 75 away from 79, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 15 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 3122895.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 3122895.26
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 3122895.266
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 3122895.266 with a remainder of 0.001.
