215778 divided by 77 
Our goal is to divide 215778 by 77.

On to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 77

Let's proceed to step 2:
77 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 77

On to step 3:
77 goes into 215 2 times with a remainder of 61.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 154 from 215, we get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 77

Going ahead to step 4:
617 divided by 77 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 616 from 617 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 77

Step 5:
The number 77 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 77

Moving on to step 6:
77 can be fit into 178 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2802.0
The remainder is 24 after subtracting 154 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
77 goes into 240 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 2802.3
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 77, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2802.31
If we subtract 77 from 90, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
If we divide 130 by 77, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 2802.311
If we take 77 away from 130, we end up 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.

The final result is 2802.311 with a remainder of 0.0053.
