Let's divide 81093812 by 216
Let's see how many times 216 fits into 81093812.

Advancing to step 1:
216 goes into 8 0 times 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.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 216

Let's proceed to step 2:
The number 216 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 216

Going ahead to step 3:
The number 216 fits into 810 3 times, leaving a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 648 away from 810, we end up with 162.
Append the next digit (9) from the dividend to 162 and continue with: 1629 / 216

On to step 4:
1629 divided by 216 is 7 with a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 1512 from 1629 and we're left with 117.
Bring next digit (3) of the dividend behind the 117 and repeat the process: 1173 / 216

Going ahead to step 5:
If we divide 1173 by 216, we get 5 and a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
If we subtract 1080 from 1173, we get 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 216

Advancing to step 6:
216 can be fit into 938 4 times, resulting in a remainder of 74.
The next digit of our result is 4. 
Result so far: 3754.0
Subtract 864 from 938 to get 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 216

On to step 7:
If we divide 741 by 216, we get 3 and a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 37543.0
Subtract 648 from 741 to get 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 216

Step 8:
216 goes into 932 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 375434.0
The remainder is 68 after subtracting 864 from 932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
If we divide 680 by 216, we get 3 and a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 375434.3
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 216, we get 1 with a remainder of 104.
The next digit of our result is 1. 
Result so far: 375434.31
The remainder is 104 after subtracting 216 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
When dividing 1040 by 216, we get 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 375434.314
If we subtract 864 from 1040, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 12:
When dividing 1760 by 216, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 375434.3148
Deduct 1728 from 1760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
The number 216 fits into 320 1 times, leaving a remainder of 104.
The next digit of our result is 1. 
Result so far: 375434.31481
Subtracting 216 from 320 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
1040 divided by 216 is 4 with a remainder of 176.
The next digit of our result is 4. 
Result so far: 375434.314814
Deduct 864 from 1040 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 15:
216 goes into 1760 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 375434.3148148
If we take 1728 away from 1760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
If we divide 320 by 216, we get 1 and a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 375434.31481481
If we subtract 216 from 320, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 375434.31481481 with a balance of 1.04e-07.
