86936405 ÷ 343 
We're looking to find how many times 343 goes into 86936405.

Advancing to step 1:
8 divided by 343 is 0 with a remainder of 8.
Write down 0 as next digit of the 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 / 343

On to step 2:
The number 343 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 343

Let's proceed to step 3:
When dividing 869 by 343, we get 2 with a remainder of 183.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 686 from 869 leaves us with 183.
Grab the next digit (3) from the dividend, add it to 183, then carry on: 1833 / 343

Going ahead to step 4:
343 goes into 1833 5 times with a remainder of 118.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1715 from 1833 to get 118.
Include the next digit (6) from the dividend after 118, then repeat: 1186 / 343

Moving on to step 5:
1186 divided by 343 is 3 with a remainder of 157.
The next digit of our result is 3. 
Result so far: 253.0
Subtracting 1029 from 1186 leaves us with 157.
Fetch the next digit (4) from the dividend, attach it to 157 and continue: 1574 / 343

Going ahead to step 6:
343 can be fit into 1574 4 times, resulting in a remainder of 202.
The next digit of our result is 4. 
Result so far: 2534.0
If we take 1372 away from 1574, we end up with 202.
Fetch the next digit (0) from the dividend, attach it to 202 and continue: 2020 / 343

Going ahead to step 7:
343 can be fit into 2020 5 times, resulting in a remainder of 305.
The next digit of our result is 5. 
Result so far: 25345.0
Subtract 1715 from 2020 to get 305.
Append the next digit (5) from the dividend to 305 and continue with: 3055 / 343

Step 8:
When dividing 3055 by 343, we get 8 with a remainder of 311.
The number 8 becomes the next digit in our result. 
Result so far: 253458.0
The remainder is 311 after subtracting 2744 from 3055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
343 goes into 3110 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 253458.9
The remainder is 23 after subtracting 3087 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
230 divided by 343 is 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 253458.9
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
343 can be fit into 2300 6 times, resulting in a remainder of 242.
Put 6 as the next digit of the answer. 
Result so far: 253458.906
If we take 2058 away from 2300, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 12:
2420 divided by 343 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 253458.9067
If we subtract 2401 from 2420, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
190 divided by 343 is 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 253458.9067
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 14:
When dividing 1900 by 343, we get 5 with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 253458.906705
Subtract 1715 from 1900 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 15:
1850 divided by 343 is 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 253458.9067055
The remainder is 135 after subtracting 1715 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

In conclusion, the division gives 253458.9067055 with a balance of 1.35e-06.
