We're dividing 78003654 by 216 
Let's see how many times 216 fits into 78003654.

Step 1:
If we divide 7 by 216, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 216

Moving on to step 2:
If we divide 78 by 216, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 216

Moving on to step 3:
216 can be fit into 780 3 times, resulting in a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 648 away from 780, we end up with 132.
Fetch the next digit (0) from the dividend, attach it to 132 and continue: 1320 / 216

Going ahead to step 4:
When dividing 1320 by 216, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 24 after subtracting 1296 from 1320.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 216

Step 5:
243 divided by 216 is 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
Deduct 216 from 243 and we're left with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 216

Going ahead to step 6:
276 divided by 216 is 1 with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 3611.0
The remainder is 60 after subtracting 216 from 276.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 216

Let's proceed to step 7:
If we divide 605 by 216, we get 2 and a remainder of 173.
Record the quotient 2 as the next digit in the result. 
Result so far: 36112.0
If we subtract 432 from 605, we get 173.
Grab the next digit (4) from the dividend, add it to 173, then carry on: 1734 / 216

Moving on to step 8:
216 can be fit into 1734 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 361128.0
Subtracting 1728 from 1734 leaves us 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.

Advancing to step 9:
216 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 361128.0
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.

Let's proceed to step 10:
600 divided by 216 is 2 with a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 361128.02
Subtract 432 from 600 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.

Moving on to step 11:
1680 divided by 216 is 7 with a remainder of 168.
The number 7 becomes the next digit in our result. 
Result so far: 361128.027
Deduct 1512 from 1680 and we're left 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.

Step 12:
When dividing 1680 by 216, we get 7 with a remainder of 168.
Put 7 as the next digit of the answer. 
Result so far: 361128.0277
If we take 1512 away from 1680, we end up 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.

The final outcome is 361128.0277, with a leftover of 0.00168.
