We look at the division of 74280356 by 485 
We want to figure out the number of times 74280356 can be divided by 485.

Going ahead to step 1:
When dividing 7 by 485, 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.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 485

Advancing to step 2:
When dividing 74 by 485, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 485

Step 3:
The number 485 fits into 742 1 times, leaving a remainder of 257.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 485 from 742 to get 257.
Grab the next digit (8) from the dividend, add it to 257, then carry on: 2578 / 485

Advancing to step 4:
When dividing 2578 by 485, we get 5 with a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2425 from 2578, we get 153.
Bring next digit (0) of the dividend behind the 153 and repeat the process: 1530 / 485

On to step 5:
The number 485 fits into 1530 3 times, leaving a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 153.0
If we take 1455 away from 1530, we end up with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 485

Let's proceed to step 6:
The number 485 fits into 753 1 times, leaving a remainder of 268.
Use 1 as the next digit of our solution. 
Result so far: 1531.0
Subtracting 485 from 753 leaves us with 268.
Bring next digit (5) of the dividend behind the 268 and repeat the process: 2685 / 485

On to step 7:
2685 divided by 485 is 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 15315.0
Deduct 2425 from 2685 and we're left with 260.
Include the next digit (6) from the dividend after 260, then repeat: 2606 / 485

On to step 8:
485 goes into 2606 5 times with a remainder of 181.
Write down 5 as next digit of the result. 
Result so far: 153155.0
Subtract 2425 from 2606 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 9:
If we divide 1810 by 485, we get 3 and a remainder of 355.
Record the quotient 3 as the next digit in the result. 
Result so far: 153155.3
Subtract 1455 from 1810 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 10:
When dividing 3550 by 485, we get 7 with a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 153155.37
Deduct 3395 from 3550 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 11:
485 goes into 1550 3 times with a remainder of 95.
The next digit of our result is 3. 
Result so far: 153155.373
If we subtract 1455 from 1550, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 12:
If we divide 950 by 485, we get 1 and a remainder of 465.
Write down 1 as next digit of the result. 
Result so far: 153155.3731
Subtract 485 from 950 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 13:
485 goes into 4650 9 times with a remainder of 285.
The next digit of our result is 9. 
Result so far: 153155.37319
If we subtract 4365 from 4650, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 14:
2850 divided by 485 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 153155.373195
Subtracting 2425 from 2850 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 15:
4250 divided by 485 is 8 with a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 153155.3731958
Subtracting 3880 from 4250 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 16:
If we divide 3700 by 485, we get 7 and a remainder of 305.
The next digit of our result is 7. 
Result so far: 153155.37319587
Deduct 3395 from 3700 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The final result is 153155.37319587 with a remainder of 3.05e-07.
