Let's divide 54218 by 15
The aim is to understand the frequency of 15 in 54218.

Let's proceed to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

Moving on to step 2:
When dividing 54 by 15, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 9 after subtracting 45 from 54.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 15

On to step 3:
If we divide 92 by 15, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtracting 90 from 92 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 15

Advancing to step 4:
When dividing 21 by 15, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
Deduct 15 from 21 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 15

On to step 5:
15 can be fit into 68 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3614.0
Subtract 60 from 68 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 6:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3614.5
Deduct 75 from 80 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3614.53
Subtract 45 from 50 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.

Let's proceed to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3614.533
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 3614.533, and the remainder is 0.0005.
