948843 ÷ 15 
The aim is to understand the frequency of 15 in 948843.

Going ahead to step 1:
When dividing 9 by 15, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 15

Let's proceed to step 2:
94 divided by 15 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 90 from 94 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

Going ahead to step 3:
15 goes into 48 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 45 from 48 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 15

Let's proceed to step 4:
15 can be fit into 38 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 632.0
If we take 30 away from 38, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 15

Advancing to step 5:
15 goes into 84 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 6325.0
If we take 75 away from 84, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 15

Advancing to step 6:
15 can be fit into 93 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 63256.0
Subtracting 90 from 93 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 63256.2
If we subtract 30 from 30, we get 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 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 63256.2
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.

Let's proceed to step 9:
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: 63256.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 63256.2, and the remainder is 0.0.
