We're dividing 86154310 by 699 
We want to divide 86154310 by 699.

Step 1:
699 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the 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 / 699

Step 2:
699 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.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 699

Let's proceed to step 3:
861 divided by 699 is 1 with a remainder of 162.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 699 from 861 to get 162.
Fetch the next digit (5) from the dividend, attach it to 162 and continue: 1625 / 699

Advancing to step 4:
The number 699 fits into 1625 2 times, leaving a remainder of 227.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 227 after subtracting 1398 from 1625.
Include the next digit (4) from the dividend after 227, then repeat: 2274 / 699

On to step 5:
If we divide 2274 by 699, we get 3 and a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 2097 from 2274 to get 177.
Bring next digit (3) of the dividend behind the 177 and repeat the process: 1773 / 699

Advancing to step 6:
699 goes into 1773 2 times with a remainder of 375.
Put 2 as the next digit of the answer. 
Result so far: 1232.0
The remainder is 375 after subtracting 1398 from 1773.
Fetch the next digit (1) from the dividend, attach it to 375 and continue: 3751 / 699

Step 7:
699 goes into 3751 5 times with a remainder of 256.
Use 5 as the next digit of our solution. 
Result so far: 12325.0
Subtracting 3495 from 3751 leaves us with 256.
Append the next digit (0) from the dividend to 256 and continue with: 2560 / 699

On to step 8:
The number 699 fits into 2560 3 times, leaving a remainder of 463.
The next digit of our result is 3. 
Result so far: 123253.0
The remainder is 463 after subtracting 2097 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 9:
699 can be fit into 4630 6 times, resulting in a remainder of 436.
The next digit of our result is 6. 
Result so far: 123253.6
If we subtract 4194 from 4630, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 10:
4360 divided by 699 is 6 with a remainder of 166.
The next digit of our result is 6. 
Result so far: 123253.66
The remainder is 166 after subtracting 4194 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

In conclusion, the division gives 123253.66 with a balance of 0.166.
