Let's divide 991021 by 24
We want to figure out the number of times 991021 can be divided by 24.

Step 1:
When dividing 9 by 24, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 24

Advancing to step 2:
24 can be fit into 99 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 3 after subtracting 96 from 99.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 24

Going ahead to step 3:
31 divided by 24 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 24 from 31 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 24

Advancing to step 4:
70 divided by 24 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 412.0
If we subtract 48 from 70, we get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 24

Let's proceed to step 5:
If we divide 222 by 24, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4129.0
If we take 216 away from 222, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 24

Step 6:
When dividing 61 by 24, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 41292.0
The remainder is 13 after subtracting 48 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 24 fits into 130 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 41292.5
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 24, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 41292.54
Subtracting 96 from 100 leaves us 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.

Going ahead to step 9:
24 goes into 40 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 41292.541
If we subtract 24 from 40, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
24 goes into 160 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 41292.5416
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 41292.54166
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 41292.54166, and the remainder is 1.6e-05.
