We're dividing 21270978 by 264 
Let's see how many times 264 fits into 21270978.

On to step 1:
264 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 264

Moving on to step 2:
264 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 264

Going ahead to step 3:
When dividing 212 by 264, we get 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Bring next digit (7) of the dividend behind the 212 and repeat the process: 2127 / 264

Advancing to step 4:
When dividing 2127 by 264, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 15 after subtracting 2112 from 2127.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 264

Let's proceed to step 5:
264 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 150 leaves us with 150.
Append the next digit (9) from the dividend to 150 and continue with: 1509 / 264

Let's proceed to step 6:
When dividing 1509 by 264, we get 5 with a remainder of 189.
The next digit of our result is 5. 
Result so far: 805.0
Deduct 1320 from 1509 and we're left with 189.
Bring next digit (7) of the dividend behind the 189 and repeat the process: 1897 / 264

Moving on to step 7:
If we divide 1897 by 264, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 8057.0
If we take 1848 away from 1897, we end up with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 264

On to step 8:
264 can be fit into 498 1 times, resulting in a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 80571.0
If we take 264 away from 498, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
264 can be fit into 2340 8 times, resulting in a remainder of 228.
Record the quotient 8 as the next digit in the result. 
Result so far: 80571.8
The remainder is 228 after subtracting 2112 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
If we divide 2280 by 264, we get 8 and a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 80571.88
If we take 2112 away from 2280, 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.

Our division results in 80571.88 with a remaining 0.168.
