We look at the division of 68393954 by 216 
Our goal is to divide 68393954 by 216.

Step 1:
If we divide 6 by 216, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 216

Advancing to step 2:
216 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 216

Moving on to step 3:
When dividing 683 by 216, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 648 from 683 and we're left with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 216

Going ahead to step 4:
216 goes into 359 1 times with a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 216 from 359, we get 143.
Bring next digit (3) of the dividend behind the 143 and repeat the process: 1433 / 216

Moving on to step 5:
216 can be fit into 1433 6 times, resulting in a remainder of 137.
Write down 6 as next digit of the result. 
Result so far: 316.0
If we subtract 1296 from 1433, we get 137.
Take the next digit (9) from the dividend and append it to 137, then repeat: 1379 / 216

Let's proceed to step 6:
When dividing 1379 by 216, we get 6 with a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 3166.0
Subtract 1296 from 1379 to get 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 216

On to step 7:
216 goes into 835 3 times with a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 31663.0
Deduct 648 from 835 and we're left with 187.
Fetch the next digit (4) from the dividend, attach it to 187 and continue: 1874 / 216

Going ahead to step 8:
216 goes into 1874 8 times with a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 316638.0
If we subtract 1728 from 1874, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
When dividing 1460 by 216, we get 6 with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 316638.6
The remainder is 164 after subtracting 1296 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
When dividing 1640 by 216, we get 7 with a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 316638.67
If we take 1512 away from 1640, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
216 goes into 1280 5 times with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 316638.675
If we subtract 1080 from 1280, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
216 can be fit into 2000 9 times, resulting in a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 316638.6759
Subtract 1944 from 2000 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
216 can be fit into 560 2 times, resulting in a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 316638.67592
Subtract 432 from 560 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
If we divide 1280 by 216, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 316638.675925
If we take 1080 away from 1280, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
The number 216 fits into 2000 9 times, leaving a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 316638.6759259
If we take 1944 away from 2000, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
When dividing 560 by 216, we get 2 with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 316638.67592592
Subtracting 432 from 560 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 316638.67592592 and a remainder of 1.28e-07.
