86221385 ÷ 392 
Our goal is to divide 86221385 by 392.

Moving on to step 1:
392 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
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 392

On to step 2:
If we divide 86 by 392, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 392

Step 3:
392 goes into 862 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 78 after subtracting 784 from 862.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 392

On to step 4:
392 can be fit into 782 1 times, resulting in a remainder of 390.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 390 after subtracting 392 from 782.
Fetch the next digit (1) from the dividend, attach it to 390 and continue: 3901 / 392

Going ahead to step 5:
3901 divided by 392 is 9 with a remainder of 373.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Deduct 3528 from 3901 and we're left with 373.
Take the next digit (3) from the dividend and append it to 373, then repeat: 3733 / 392

Let's proceed to step 6:
If we divide 3733 by 392, we get 9 and a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 2199.0
The remainder is 205 after subtracting 3528 from 3733.
Include the next digit (8) from the dividend after 205, then repeat: 2058 / 392

Going ahead to step 7:
If we divide 2058 by 392, we get 5 and a remainder of 98.
The next digit of our result is 5. 
Result so far: 21995.0
If we take 1960 away from 2058, we end up with 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 392

Moving on to step 8:
If we divide 985 by 392, we get 2 and a remainder of 201.
Put 2 as the next digit of the answer. 
Result so far: 219952.0
The remainder is 201 after subtracting 784 from 985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 9:
2010 divided by 392 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 219952.5
Deduct 1960 from 2010 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
392 goes into 500 1 times with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 219952.51
Subtract 392 from 500 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
If we divide 1080 by 392, we get 2 and a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 219952.512
If we take 784 away from 1080, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 12:
The number 392 fits into 2960 7 times, leaving a remainder of 216.
Put 7 as the next digit of the answer. 
Result so far: 219952.5127
If we take 2744 away from 2960, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 13:
2160 divided by 392 is 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 219952.51275
The remainder is 200 after subtracting 1960 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
392 goes into 2000 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 219952.512755
Subtracting 1960 from 2000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 219952.512755 with a balance of 4e-06.
