We're dividing 74551279 by 30 
We want to figure out the number of times 74551279 can be divided by 30.

Going ahead to step 1:
The number 30 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 30

Step 2:
If we divide 74 by 30, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 74 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 30

Going ahead to step 3:
145 divided by 30 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 120 from 145, we get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 30

Advancing to step 4:
When dividing 255 by 30, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 248.0
If we subtract 240 from 255, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 30

Advancing to step 5:
151 divided by 30 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2485.0
Subtracting 150 from 151 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 30

On to step 6:
If we divide 12 by 30, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 24850.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 30

Going ahead to step 7:
30 can be fit into 127 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 248504.0
Subtracting 120 from 127 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 30

Let's proceed to step 8:
30 goes into 79 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2485042.0
The remainder is 19 after subtracting 60 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
30 can be fit into 190 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2485042.6
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2485042.63
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 2485042.633
Subtract 90 from 100 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.

After the division, we end up with 2485042.633 and a remainder of 0.001.
