21655948 ÷ 264 
We want to figure out the number of times 21655948 can be divided by 264.

On to step 1:
When dividing 2 by 264, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 264

Advancing to step 2:
264 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 264

Moving on to step 3:
264 goes into 216 0 times with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 264

Step 4:
If we divide 2165 by 264, we get 8 and a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 2112 from 2165 leaves us with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 264

Going ahead to step 5:
The number 264 fits into 535 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 528 from 535, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 264

On to step 6:
When dividing 79 by 264, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 820.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 264

Advancing to step 7:
794 divided by 264 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 8203.0
Subtracting 792 from 794 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 264

Going ahead to step 8:
28 divided by 264 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 82030.0
Deduct 0 from 28 and we're left 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.

Moving on to step 9:
If we divide 280 by 264, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 82030.1
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
264 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 82030.1
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
264 can be fit into 1600 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 82030.106
Subtract 1584 from 1600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
264 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 82030.106
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
If we divide 1600 by 264, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 82030.10606
If we take 1584 away from 1600, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
264 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 82030.10606
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
264 can be fit into 1600 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 82030.1060606
If we take 1584 away from 1600, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
When dividing 160 by 264, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 82030.1060606
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 82030.1060606 with a remainder of 1.6e-07.
