We're dividing 74243124 by 300 
We want to divide 74243124 by 300.

Going ahead to step 1:
When dividing 7 by 300, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 300

Moving on to step 2:
If we divide 74 by 300, we get 0 and a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 300

Going ahead to step 3:
The number 300 fits into 742 2 times, leaving a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 600 from 742, we get 142.
Take the next digit (4) from the dividend and append it to 142, then repeat: 1424 / 300

Moving on to step 4:
If we divide 1424 by 300, we get 4 and a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 224 after subtracting 1200 from 1424.
Bring next digit (3) of the dividend behind the 224 and repeat the process: 2243 / 300

Step 5:
The number 300 fits into 2243 7 times, leaving a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
The remainder is 143 after subtracting 2100 from 2243.
Append the next digit (1) from the dividend to 143 and continue with: 1431 / 300

Going ahead to step 6:
If we divide 1431 by 300, we get 4 and a remainder of 231.
Use 4 as the next digit of our solution. 
Result so far: 2474.0
Deduct 1200 from 1431 and we're left with 231.
Take the next digit (2) from the dividend and append it to 231, then repeat: 2312 / 300

Moving on to step 7:
300 goes into 2312 7 times with a remainder of 212.
Record the quotient 7 as the next digit in the result. 
Result so far: 24747.0
Subtract 2100 from 2312 to get 212.
Fetch the next digit (4) from the dividend, attach it to 212 and continue: 2124 / 300

On to step 8:
The number 300 fits into 2124 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 247477.0
If we take 2100 away from 2124, we end up 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.

Let's proceed to step 9:
240 divided by 300 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 247477.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
When dividing 2400 by 300, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 247477.08
If we take 2400 away from 2400, 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.

Step 11:
0 divided by 300 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 247477.08
Subtract 0 from 0 to 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 12:
If we divide 0 by 300, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 247477.08
Subtract 0 from 0 to 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.

Our division results in 247477.08 with a remaining 0.0.
