We're dividing 74252730 by 489 
Our goal is to divide 74252730 by 489.

Step 1:
7 divided by 489 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 489

Step 2:
The number 489 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 489

Advancing to step 3:
489 goes into 742 1 times with a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 489 from 742 and we're left with 253.
Append the next digit (5) from the dividend to 253 and continue with: 2535 / 489

Let's proceed to step 4:
489 goes into 2535 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 2445 from 2535, we get 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 489

Moving on to step 5:
When dividing 902 by 489, we get 1 with a remainder of 413.
The next digit of our result is 1. 
Result so far: 151.0
If we take 489 away from 902, we end up with 413.
Append the next digit (7) from the dividend to 413 and continue with: 4137 / 489

Advancing to step 6:
489 can be fit into 4137 8 times, resulting in a remainder of 225.
Use 8 as the next digit of our solution. 
Result so far: 1518.0
Subtract 3912 from 4137 to get 225.
Grab the next digit (3) from the dividend, add it to 225, then carry on: 2253 / 489

Let's proceed to step 7:
489 goes into 2253 4 times with a remainder of 297.
Record the quotient 4 as the next digit in the result. 
Result so far: 15184.0
The remainder is 297 after subtracting 1956 from 2253.
Include the next digit (0) from the dividend after 297, then repeat: 2970 / 489

Moving on to step 8:
489 can be fit into 2970 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 151846.0
If we subtract 2934 from 2970, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
The number 489 fits into 360 0 times, leaving a remainder of 360.
The next digit of our result is 0. 
Result so far: 151846.0
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
489 can be fit into 3600 7 times, resulting in a remainder of 177.
The next digit of our result is 7. 
Result so far: 151846.07
Deduct 3423 from 3600 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 11:
If we divide 1770 by 489, we get 3 and a remainder of 303.
Write down 3 as next digit of the result. 
Result so far: 151846.073
If we take 1467 away from 1770, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 12:
489 goes into 3030 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 151846.0736
Subtracting 2934 from 3030 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
960 divided by 489 is 1 with a remainder of 471.
Put 1 as the next digit of the answer. 
Result so far: 151846.07361
Deduct 489 from 960 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Let's proceed to step 14:
489 goes into 4710 9 times with a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 151846.073619
The remainder is 309 after subtracting 4401 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 15:
489 goes into 3090 6 times with a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 151846.0736196
The remainder is 156 after subtracting 2934 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 16:
489 goes into 1560 3 times with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 151846.07361963
The remainder is 93 after subtracting 1467 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final outcome is 151846.07361963, with a leftover of 9.3e-08.
