We're dividing 86690494 by 493 
We're looking to find how many times 493 goes into 86690494.

On to step 1:
When dividing 8 by 493, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 493

Moving on to step 2:
493 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 493

On to step 3:
When dividing 866 by 493, we get 1 with a remainder of 373.
The next digit of our result is 1. 
Result so far: 1.0
If we take 493 away from 866, we end up with 373.
Bring next digit (9) of the dividend behind the 373 and repeat the process: 3739 / 493

On to step 4:
If we divide 3739 by 493, we get 7 and a remainder of 288.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3451 away from 3739, we end up with 288.
Bring next digit (0) of the dividend behind the 288 and repeat the process: 2880 / 493

On to step 5:
493 can be fit into 2880 5 times, resulting in a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 175.0
The remainder is 415 after subtracting 2465 from 2880.
Bring next digit (4) of the dividend behind the 415 and repeat the process: 4154 / 493

Going ahead to step 6:
4154 divided by 493 is 8 with a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 1758.0
If we take 3944 away from 4154, we end up with 210.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 493

Going ahead to step 7:
2109 divided by 493 is 4 with a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 17584.0
The remainder is 137 after subtracting 1972 from 2109.
Include the next digit (4) from the dividend after 137, then repeat: 1374 / 493

Step 8:
The number 493 fits into 1374 2 times, leaving a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 175842.0
Deduct 986 from 1374 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 9:
493 can be fit into 3880 7 times, resulting in a remainder of 429.
Use 7 as the next digit of our solution. 
Result so far: 175842.7
Subtracting 3451 from 3880 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 10:
When dividing 4290 by 493, we get 8 with a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 175842.78
Subtract 3944 from 4290 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 11:
3460 divided by 493 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 175842.787
If we subtract 3451 from 3460, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
The number 493 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 175842.787
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
493 goes into 900 1 times with a remainder of 407.
Write down 1 as next digit of the result. 
Result so far: 175842.78701
If we take 493 away from 900, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 14:
493 can be fit into 4070 8 times, resulting in a remainder of 126.
The next digit of our result is 8. 
Result so far: 175842.787018
If we take 3944 away from 4070, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 15:
493 can be fit into 1260 2 times, resulting in a remainder of 274.
The number 2 becomes the next digit in our result. 
Result so far: 175842.7870182
If we take 986 away from 1260, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 16:
493 can be fit into 2740 5 times, resulting in a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 175842.78701825
The remainder is 275 after subtracting 2465 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

After the division, we end up with 175842.78701825 and a remainder of 2.75e-07.
