Let's divide 12259707 by 216
We want to divide 12259707 by 216.

Let's proceed to step 1:
When dividing 1 by 216, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 216

Going ahead to step 2:
216 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 216

Step 3:
216 goes into 122 0 times with a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 216

On to step 4:
216 goes into 1225 5 times with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1080 away from 1225, we end up with 145.
Take the next digit (9) from the dividend and append it to 145, then repeat: 1459 / 216

Step 5:
If we divide 1459 by 216, we get 6 and a remainder of 163.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 1296 from 1459, we get 163.
Bring next digit (7) of the dividend behind the 163 and repeat the process: 1637 / 216

Advancing to step 6:
If we divide 1637 by 216, we get 7 and a remainder of 125.
The next digit of our result is 7. 
Result so far: 567.0
Subtracting 1512 from 1637 leaves us with 125.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 216

Step 7:
When dividing 1250 by 216, we get 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 5675.0
The remainder is 170 after subtracting 1080 from 1250.
Append the next digit (7) from the dividend to 170 and continue with: 1707 / 216

On to step 8:
If we divide 1707 by 216, we get 7 and a remainder of 195.
The next digit of our result is 7. 
Result so far: 56757.0
The remainder is 195 after subtracting 1512 from 1707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
216 goes into 1950 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 56757.9
Deduct 1944 from 1950 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 216, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 56757.9
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 216 is 2 with a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 56757.902
Subtracting 432 from 600 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
If we divide 1680 by 216, we get 7 and a remainder of 168.
Put 7 as the next digit of the answer. 
Result so far: 56757.9027
If we subtract 1512 from 1680, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
When dividing 1680 by 216, we get 7 with a remainder of 168.
The number 7 becomes the next digit in our result. 
Result so far: 56757.90277
Subtract 1512 from 1680 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 56757.90277 with a remainder of 0.000168.
