We look at the division of 99384921 by 724 
We want to figure out the number of times 99384921 can be divided by 724.

Advancing to step 1:
When dividing 9 by 724, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 724

Step 2:
724 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 724

Let's proceed to step 3:
The number 724 fits into 993 1 times, leaving a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 724 from 993 leaves us with 269.
Append the next digit (8) from the dividend to 269 and continue with: 2698 / 724

Going ahead to step 4:
724 can be fit into 2698 3 times, resulting in a remainder of 526.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 2172 away from 2698, we end up with 526.
Take the next digit (4) from the dividend and append it to 526, then repeat: 5264 / 724

Moving on to step 5:
5264 divided by 724 is 7 with a remainder of 196.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
The remainder is 196 after subtracting 5068 from 5264.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 724

Advancing to step 6:
When dividing 1969 by 724, we get 2 with a remainder of 521.
Put 2 as the next digit of the answer. 
Result so far: 1372.0
Subtracting 1448 from 1969 leaves us with 521.
Append the next digit (2) from the dividend to 521 and continue with: 5212 / 724

Going ahead to step 7:
When dividing 5212 by 724, we get 7 with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 13727.0
Subtracting 5068 from 5212 leaves us with 144.
Grab the next digit (1) from the dividend, add it to 144, then carry on: 1441 / 724

Moving on to step 8:
724 goes into 1441 1 times with a remainder of 717.
Use 1 as the next digit of our solution. 
Result so far: 137271.0
The remainder is 717 after subtracting 724 from 1441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Step 9:
When dividing 7170 by 724, we get 9 with a remainder of 654.
Use 9 as the next digit of our solution. 
Result so far: 137271.9
Deduct 6516 from 7170 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 10:
6540 divided by 724 is 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 137271.99
Subtracting 6516 from 6540 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 137271.99 with a remaining 0.024.
