Let's divide 86516318 by 489
We're looking to find how many times 489 goes into 86516318.

Going ahead to step 1:
8 divided by 489 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 489

Advancing to step 2:
The number 489 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 489

On to step 3:
489 can be fit into 865 1 times, resulting in a remainder of 376.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 489 from 865 and we're left with 376.
Take the next digit (1) from the dividend and append it to 376, then repeat: 3761 / 489

Let's proceed to step 4:
489 goes into 3761 7 times with a remainder of 338.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 3423 from 3761 to get 338.
Include the next digit (6) from the dividend after 338, then repeat: 3386 / 489

Step 5:
If we divide 3386 by 489, we get 6 and a remainder of 452.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtracting 2934 from 3386 leaves us with 452.
Append the next digit (3) from the dividend to 452 and continue with: 4523 / 489

Going ahead to step 6:
4523 divided by 489 is 9 with a remainder of 122.
Record the quotient 9 as the next digit in the result. 
Result so far: 1769.0
If we take 4401 away from 4523, we end up with 122.
Grab the next digit (1) from the dividend, add it to 122, then carry on: 1221 / 489

Going ahead to step 7:
When dividing 1221 by 489, we get 2 with a remainder of 243.
Record the quotient 2 as the next digit in the result. 
Result so far: 17692.0
The remainder is 243 after subtracting 978 from 1221.
Take the next digit (8) from the dividend and append it to 243, then repeat: 2438 / 489

Moving on to step 8:
489 can be fit into 2438 4 times, resulting in a remainder of 482.
Put 4 as the next digit of the answer. 
Result so far: 176924.0
Subtract 1956 from 2438 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 9:
If we divide 4820 by 489, we get 9 and a remainder of 419.
Use 9 as the next digit of our solution. 
Result so far: 176924.9
The remainder is 419 after subtracting 4401 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 10:
4190 divided by 489 is 8 with a remainder of 278.
The next digit of our result is 8. 
Result so far: 176924.98
If we take 3912 away from 4190, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 11:
The number 489 fits into 2780 5 times, leaving a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 176924.985
Subtracting 2445 from 2780 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 12:
The number 489 fits into 3350 6 times, leaving a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 176924.9856
If we subtract 2934 from 3350, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 13:
489 can be fit into 4160 8 times, resulting in a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 176924.98568
If we subtract 3912 from 4160, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 14:
489 can be fit into 2480 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 176924.985685
If we take 2445 away from 2480, 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.

Step 15:
The number 489 fits into 350 0 times, leaving a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 176924.985685
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 16:
489 can be fit into 3500 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 176924.98568507
Subtracting 3423 from 3500 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 176924.98568507, with a leftover of 7.7e-08.
