86038140 ÷ 864 
Let's see how many times 864 fits into 86038140.

Let's proceed to step 1:
When dividing 8 by 864, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 864

Let's proceed to step 2:
If we divide 86 by 864, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 864

Moving on to step 3:
The number 864 fits into 860 0 times, leaving a remainder of 860.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 860 and we're left with 860.
Take the next digit (3) from the dividend and append it to 860, then repeat: 8603 / 864

Advancing to step 4:
8603 divided by 864 is 9 with a remainder of 827.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 827 after subtracting 7776 from 8603.
Append the next digit (8) from the dividend to 827 and continue with: 8278 / 864

Step 5:
If we divide 8278 by 864, we get 9 and a remainder of 502.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 7776 from 8278, we get 502.
Bring next digit (1) of the dividend behind the 502 and repeat the process: 5021 / 864

Going ahead to step 6:
864 can be fit into 5021 5 times, resulting in a remainder of 701.
Record the quotient 5 as the next digit in the result. 
Result so far: 995.0
Subtract 4320 from 5021 to get 701.
Bring next digit (4) of the dividend behind the 701 and repeat the process: 7014 / 864

Let's proceed to step 7:
7014 divided by 864 is 8 with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 9958.0
Subtract 6912 from 7014 to get 102.
Fetch the next digit (0) from the dividend, attach it to 102 and continue: 1020 / 864

Advancing to step 8:
When dividing 1020 by 864, we get 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 99581.0
The remainder is 156 after subtracting 864 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
When dividing 1560 by 864, we get 1 with a remainder of 696.
Use 1 as the next digit of our solution. 
Result so far: 99581.1
If we subtract 864 from 1560, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 10:
If we divide 6960 by 864, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 99581.18
The remainder is 48 after subtracting 6912 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
480 divided by 864 is 0 with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 99581.18
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
864 goes into 4800 5 times with a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 99581.1805
The remainder is 480 after subtracting 4320 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
The number 864 fits into 4800 5 times, leaving a remainder of 480.
Write down 5 as next digit of the result. 
Result so far: 99581.18055
Subtract 4320 from 4800 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 99581.18055 and a remainder of 0.00048.
