We're dividing 86888861 by 216 
We want to divide 86888861 by 216.

Let's proceed to step 1:
If we divide 8 by 216, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 216

On to step 2:
When dividing 86 by 216, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 216

Step 3:
216 can be fit into 868 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 4 after subtracting 864 from 868.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 216

Advancing to step 4:
216 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 216

On to step 5:
When dividing 488 by 216, we get 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
Subtracting 432 from 488 leaves us with 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 216

On to step 6:
216 goes into 568 2 times with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 4022.0
Deduct 432 from 568 and we're left with 136.
Append the next digit (6) from the dividend to 136 and continue with: 1366 / 216

Going ahead to step 7:
If we divide 1366 by 216, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 40226.0
The remainder is 70 after subtracting 1296 from 1366.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 216

Advancing to step 8:
If we divide 701 by 216, we get 3 and a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 402263.0
Subtracting 648 from 701 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
If we divide 530 by 216, we get 2 and a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 402263.2
If we take 432 away from 530, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
The number 216 fits into 980 4 times, leaving a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 402263.24
If we subtract 864 from 980, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
When dividing 1160 by 216, we get 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 402263.245
If we subtract 1080 from 1160, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 216 is 3 with a remainder of 152.
Write down 3 as next digit of the result. 
Result so far: 402263.2453
Subtracting 648 from 800 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
If we divide 1520 by 216, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 402263.24537
Subtracting 1512 from 1520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 216, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 402263.24537
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
If we divide 800 by 216, we get 3 and a remainder of 152.
The next digit of our result is 3. 
Result so far: 402263.2453703
Subtracting 648 from 800 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 16:
When dividing 1520 by 216, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 402263.24537037
Deduct 1512 from 1520 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 402263.24537037, with a leftover of 8e-09.
