Let's divide 21279666 by 854
Our goal is to divide 21279666 by 854.

Advancing to step 1:
When dividing 2 by 854, we get 0 with 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 / 854

Going ahead to step 2:
When dividing 21 by 854, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 854

Going ahead to step 3:
854 can be fit into 212 0 times, resulting in a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Fetch the next digit (7) from the dividend, attach it to 212 and continue: 2127 / 854

On to step 4:
2127 divided by 854 is 2 with a remainder of 419.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1708 from 2127 and we're left with 419.
Append the next digit (9) from the dividend to 419 and continue with: 4199 / 854

Step 5:
854 goes into 4199 4 times with a remainder of 783.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 783 after subtracting 3416 from 4199.
Bring next digit (6) of the dividend behind the 783 and repeat the process: 7836 / 854

Moving on to step 6:
7836 divided by 854 is 9 with a remainder of 150.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
Deduct 7686 from 7836 and we're left with 150.
Grab the next digit (6) from the dividend, add it to 150, then carry on: 1506 / 854

On to step 7:
854 can be fit into 1506 1 times, resulting in a remainder of 652.
Record the quotient 1 as the next digit in the result. 
Result so far: 2491.0
Deduct 854 from 1506 and we're left with 652.
Take the next digit (6) from the dividend and append it to 652, then repeat: 6526 / 854

Going ahead to step 8:
6526 divided by 854 is 7 with a remainder of 548.
Record the quotient 7 as the next digit in the result. 
Result so far: 24917.0
If we take 5978 away from 6526, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 9:
854 can be fit into 5480 6 times, resulting in a remainder of 356.
The next digit of our result is 6. 
Result so far: 24917.6
Subtracting 5124 from 5480 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 10:
If we divide 3560 by 854, we get 4 and a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 24917.64
If we subtract 3416 from 3560, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
When dividing 1440 by 854, we get 1 with a remainder of 586.
The number 1 becomes the next digit in our result. 
Result so far: 24917.641
If we subtract 854 from 1440, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 12:
The number 854 fits into 5860 6 times, leaving a remainder of 736.
Record the quotient 6 as the next digit in the result. 
Result so far: 24917.6416
The remainder is 736 after subtracting 5124 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 13:
When dividing 7360 by 854, we get 8 with a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 24917.64168
Subtract 6832 from 7360 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 14:
If we divide 5280 by 854, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 24917.641686
Subtracting 5124 from 5280 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 15:
1560 divided by 854 is 1 with a remainder of 706.
Put 1 as the next digit of the answer. 
Result so far: 24917.6416861
Subtract 854 from 1560 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 16:
7060 divided by 854 is 8 with a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 24917.64168618
Subtracting 6832 from 7060 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 24917.64168618, and the remainder is 2.28e-07.
