We're dividing 86243423 by 483 
We want to figure out the number of times 86243423 can be divided by 483.

On to step 1:
If we divide 8 by 483, we get 0 and 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.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 483

Going ahead to step 2:
The number 483 fits into 86 0 times, leaving 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.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 483

Step 3:
483 goes into 862 1 times with a remainder of 379.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 483 from 862 leaves us with 379.
Grab the next digit (4) from the dividend, add it to 379, then carry on: 3794 / 483

Advancing to step 4:
When dividing 3794 by 483, we get 7 with a remainder of 413.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3381 from 3794 leaves us with 413.
Include the next digit (3) from the dividend after 413, then repeat: 4133 / 483

Let's proceed to step 5:
4133 divided by 483 is 8 with a remainder of 269.
The next digit of our result is 8. 
Result so far: 178.0
Subtract 3864 from 4133 to get 269.
Bring next digit (4) of the dividend behind the 269 and repeat the process: 2694 / 483

On to step 6:
The number 483 fits into 2694 5 times, leaving a remainder of 279.
Put 5 as the next digit of the answer. 
Result so far: 1785.0
Subtract 2415 from 2694 to get 279.
Append the next digit (2) from the dividend to 279 and continue with: 2792 / 483

Going ahead to step 7:
The number 483 fits into 2792 5 times, leaving a remainder of 377.
Put 5 as the next digit of the answer. 
Result so far: 17855.0
If we subtract 2415 from 2792, we get 377.
Fetch the next digit (3) from the dividend, attach it to 377 and continue: 3773 / 483

Advancing to step 8:
If we divide 3773 by 483, we get 7 and a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 178557.0
If we subtract 3381 from 3773, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 9:
483 can be fit into 3920 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 178557.8
If we take 3864 away from 3920, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
The number 483 fits into 560 1 times, leaving a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 178557.81
Subtract 483 from 560 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
483 goes into 770 1 times with a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 178557.811
If we take 483 away from 770, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

The quotient of the division is 178557.811, and the remainder is 0.0287.
