We're dividing 21786 by 76 
We're looking to find how many times 76 goes into 21786.

On to step 1:
2 divided by 76 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 76

Moving on to step 2:
21 divided by 76 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 76

Step 3:
76 goes into 217 2 times with a remainder of 65.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 65 after subtracting 152 from 217.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 76

Advancing to step 4:
If we divide 658 by 76, we get 8 and a remainder of 50.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 50 after subtracting 608 from 658.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 76

Advancing to step 5:
When dividing 506 by 76, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 286.0
If we subtract 456 from 506, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 6:
500 divided by 76 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 286.6
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.

Moving on to step 7:
If we divide 440 by 76, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 286.65
Subtracting 380 from 440 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
If we divide 600 by 76, we get 7 and a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 286.657
The remainder is 68 after subtracting 532 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
If we divide 680 by 76, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 286.6578
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.

Advancing to step 10:
The number 76 fits into 720 9 times, leaving a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 286.65789
Subtract 684 from 720 to 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.

On to step 11:
360 divided by 76 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 286.657894
If we take 304 away from 360, 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.

Step 12:
The number 76 fits into 560 7 times, leaving a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 286.6578947
Subtracting 532 from 560 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
280 divided by 76 is 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 286.65789473
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 286.65789473 with a remaining 5.2e-08.
