74552150 ÷ 309 
We want to figure out the number of times 74552150 can be divided by 309.

Moving on to step 1:
When dividing 7 by 309, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 309

Advancing to step 2:
The number 309 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 309

Let's proceed to step 3:
745 divided by 309 is 2 with a remainder of 127.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 618 from 745 to get 127.
Include the next digit (5) from the dividend after 127, then repeat: 1275 / 309

Step 4:
When dividing 1275 by 309, we get 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 1236 from 1275 leaves us with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 309

Going ahead to step 5:
309 goes into 392 1 times with a remainder of 83.
The next digit of our result is 1. 
Result so far: 241.0
Deduct 309 from 392 and we're left with 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 309

Advancing to step 6:
When dividing 831 by 309, we get 2 with a remainder of 213.
Write down 2 as next digit of the result. 
Result so far: 2412.0
Deduct 618 from 831 and we're left with 213.
Append the next digit (5) from the dividend to 213 and continue with: 2135 / 309

Let's proceed to step 7:
2135 divided by 309 is 6 with a remainder of 281.
Put 6 as the next digit of the answer. 
Result so far: 24126.0
The remainder is 281 after subtracting 1854 from 2135.
Append the next digit (0) from the dividend to 281 and continue with: 2810 / 309

Let's proceed to step 8:
When dividing 2810 by 309, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 241269.0
If we take 2781 away from 2810, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
If we divide 290 by 309, we get 0 and a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 241269.0
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
When dividing 2900 by 309, we get 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 241269.09
Subtract 2781 from 2900 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 11:
If we divide 1190 by 309, we get 3 and a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 241269.093
Subtracting 927 from 1190 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 12:
If we divide 2630 by 309, we get 8 and a remainder of 158.
Use 8 as the next digit of our solution. 
Result so far: 241269.0938
Subtracting 2472 from 2630 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 13:
When dividing 1580 by 309, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 241269.09385
If we take 1545 away from 1580, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
When dividing 350 by 309, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 241269.093851
The remainder is 41 after subtracting 309 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
If we divide 410 by 309, we get 1 and a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 241269.0938511
The remainder is 101 after subtracting 309 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

After the division, we end up with 241269.0938511 and a remainder of 1.01e-06.
