86033166 ÷ 343 
Our goal is to divide 86033166 by 343.

On to step 1:
343 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 343

Let's proceed to step 2:
The number 343 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 343

Moving on to step 3:
The number 343 fits into 860 2 times, leaving a remainder of 174.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 686 from 860 to get 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 343

Let's proceed to step 4:
1743 divided by 343 is 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 1715 away from 1743, we end up with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 343

Moving on to step 5:
When dividing 283 by 343, we get 0 with a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtract 0 from 283 to get 283.
Include the next digit (1) from the dividend after 283, then repeat: 2831 / 343

Advancing to step 6:
When dividing 2831 by 343, we get 8 with a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 2508.0
Subtracting 2744 from 2831 leaves us with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 343

On to step 7:
343 can be fit into 876 2 times, resulting in a remainder of 190.
Use 2 as the next digit of our solution. 
Result so far: 25082.0
Subtract 686 from 876 to get 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 343

Step 8:
If we divide 1906 by 343, we get 5 and a remainder of 191.
The number 5 becomes the next digit in our result. 
Result so far: 250825.0
The remainder is 191 after subtracting 1715 from 1906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 9:
When dividing 1910 by 343, we get 5 with a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 250825.5
If we subtract 1715 from 1910, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 10:
343 can be fit into 1950 5 times, resulting in a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 250825.55
Subtract 1715 from 1950 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 250825.55 with a remainder of 0.235.
