We look at the division of 40080474 by 489 
We want to figure out the number of times 40080474 can be divided by 489.

Going ahead to step 1:
489 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 489

Going ahead to step 2:
If we divide 40 by 489, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 489

Step 3:
400 divided by 489 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 400 to get 400.
Grab the next digit (8) from the dividend, add it to 400, then carry on: 4008 / 489

Going ahead to step 4:
The number 489 fits into 4008 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 3912 from 4008 leaves us with 96.
Bring next digit (0) of the dividend behind the 96 and repeat the process: 960 / 489

Moving on to step 5:
489 can be fit into 960 1 times, resulting in a remainder of 471.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Deduct 489 from 960 and we're left with 471.
Grab the next digit (4) from the dividend, add it to 471, then carry on: 4714 / 489

On to step 6:
The number 489 fits into 4714 9 times, leaving a remainder of 313.
Write down 9 as next digit of the result. 
Result so far: 819.0
Subtract 4401 from 4714 to get 313.
Fetch the next digit (7) from the dividend, attach it to 313 and continue: 3137 / 489

Moving on to step 7:
When dividing 3137 by 489, we get 6 with a remainder of 203.
Write down 6 as next digit of the result. 
Result so far: 8196.0
If we subtract 2934 from 3137, we get 203.
Append the next digit (4) from the dividend to 203 and continue with: 2034 / 489

Going ahead to step 8:
If we divide 2034 by 489, we get 4 and a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 81964.0
Deduct 1956 from 2034 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
The number 489 fits into 780 1 times, leaving a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 81964.1
If we take 489 away from 780, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 10:
If we divide 2910 by 489, we get 5 and a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 81964.15
The remainder is 465 after subtracting 2445 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 11:
When dividing 4650 by 489, we get 9 with a remainder of 249.
Write down 9 as next digit of the result. 
Result so far: 81964.159
Subtracting 4401 from 4650 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 12:
2490 divided by 489 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 81964.1595
Subtract 2445 from 2490 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
If we divide 450 by 489, we get 0 and a remainder of 450.
The next digit of our result is 0. 
Result so far: 81964.1595
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 14:
The number 489 fits into 4500 9 times, leaving a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 81964.159509
Subtract 4401 from 4500 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 15:
The number 489 fits into 990 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 81964.1595092
The remainder is 12 after subtracting 978 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
If we divide 120 by 489, we get 0 and a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 81964.1595092
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 81964.1595092 and a remainder of 1.2e-07.
