86233787 ÷ 345 
We want to divide 86233787 by 345.

On to step 1:
345 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 345

Moving on to step 2:
345 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 345

Step 3:
862 divided by 345 is 2 with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 690 away from 862, we end up with 172.
Append the next digit (3) from the dividend to 172 and continue with: 1723 / 345

Moving on to step 4:
When dividing 1723 by 345, we get 4 with a remainder of 343.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1380 away from 1723, we end up with 343.
Bring next digit (3) of the dividend behind the 343 and repeat the process: 3433 / 345

Advancing to step 5:
345 can be fit into 3433 9 times, resulting in a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
The remainder is 328 after subtracting 3105 from 3433.
Include the next digit (7) from the dividend after 328, then repeat: 3287 / 345

Let's proceed to step 6:
The number 345 fits into 3287 9 times, leaving a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 2499.0
The remainder is 182 after subtracting 3105 from 3287.
Append the next digit (8) from the dividend to 182 and continue with: 1828 / 345

Let's proceed to step 7:
345 can be fit into 1828 5 times, resulting in a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 24995.0
Deduct 1725 from 1828 and we're left with 103.
Include the next digit (7) from the dividend after 103, then repeat: 1037 / 345

Step 8:
The number 345 fits into 1037 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 249953.0
Deduct 1035 from 1037 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 345, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 249953.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 345 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 249953.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 249953.0, with a leftover of 0.2.
