Let's divide 21779 by 76
Our goal is to divide 21779 by 76.

On to step 1:
76 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 76

Moving on to step 2:
If we divide 21 by 76, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 76

Step 3:
When dividing 217 by 76, we get 2 with a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 152 from 217 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 76

Step 4:
If we divide 657 by 76, we get 8 and a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 608 away from 657, we end up with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 76

Going ahead to step 5:
499 divided by 76 is 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 286.0
If we subtract 456 from 499, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 6:
When dividing 430 by 76, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 286.5
Subtracting 380 from 430 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
76 goes into 500 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 286.56
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
When dividing 440 by 76, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 286.565
The remainder is 60 after subtracting 380 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 76 fits into 600 7 times, leaving a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 286.5657
If we subtract 532 from 600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
When dividing 680 by 76, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 286.56578
If we take 608 away from 680, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
If we divide 720 by 76, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 286.565789
If we subtract 684 from 720, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
If we divide 360 by 76, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 286.5657894
If we subtract 304 from 360, we 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.

Moving on to step 13:
If we divide 560 by 76, we get 7 and a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 286.56578947
If we subtract 532 from 560, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 286.56578947, with a leftover of 2.8e-08.
