We're dividing 86453644 by 236 
Our goal is to divide 86453644 by 236.

Step 1:
8 divided by 236 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 236

Step 2:
236 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 236

Let's proceed to step 3:
The number 236 fits into 864 3 times, leaving a remainder of 156.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 708 away from 864, we end up with 156.
Include the next digit (5) from the dividend after 156, then repeat: 1565 / 236

Going ahead to step 4:
If we divide 1565 by 236, we get 6 and a remainder of 149.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 1416 from 1565, we get 149.
Fetch the next digit (3) from the dividend, attach it to 149 and continue: 1493 / 236

Moving on to step 5:
1493 divided by 236 is 6 with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 366.0
Subtract 1416 from 1493 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 236

Moving on to step 6:
The number 236 fits into 776 3 times, leaving a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3663.0
If we subtract 708 from 776, we get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 236

Moving on to step 7:
The number 236 fits into 684 2 times, leaving a remainder of 212.
The next digit of our result is 2. 
Result so far: 36632.0
If we take 472 away from 684, we end up with 212.
Bring next digit (4) of the dividend behind the 212 and repeat the process: 2124 / 236

Step 8:
236 can be fit into 2124 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 366329.0
Subtract 2124 from 2124 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 236 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 366329.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 236 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 366329.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 366329.0 with a remainder of 0.0.
