991828 ÷ 4 
The aim is to understand the frequency of 4 in 991828.

Going ahead to step 1:
4 goes into 9 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 8 from 9 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Let's proceed to step 2:
The number 4 fits into 19 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 3 after subtracting 16 from 19.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Moving on to step 3:
The number 4 fits into 31 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
Subtracting 28 from 31 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Let's proceed to step 4:
When dividing 38 by 4, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 2479.0
Deduct 36 from 38 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 4

Advancing to step 5:
4 can be fit into 22 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 24795.0
The remainder is 2 after subtracting 20 from 22.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 4

On to step 6:
When dividing 28 by 4, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 247957.0
Subtracting 28 from 28 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 7:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 247957.0
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.

Moving on to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 247957.0
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.

The quotient of the division is 247957.0, and the remainder is 0.0.
