21164564 divided by 254 
We want to figure out the number of times 21164564 can be divided by 254.

Advancing to step 1:
The number 254 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 254

Let's proceed to step 2:
254 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 254

On to step 3:
If we divide 211 by 254, we get 0 and a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Include the next digit (6) from the dividend after 211, then repeat: 2116 / 254

Step 4:
254 can be fit into 2116 8 times, resulting in a remainder of 84.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 2032 from 2116 leaves us with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 254

Let's proceed to step 5:
844 divided by 254 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 762 from 844 leaves us with 82.
Grab the next digit (5) from the dividend, add it to 82, then carry on: 825 / 254

Advancing to step 6:
The number 254 fits into 825 3 times, leaving a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 833.0
If we subtract 762 from 825, we get 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 254

Moving on to step 7:
The number 254 fits into 636 2 times, leaving a remainder of 128.
The next digit of our result is 2. 
Result so far: 8332.0
The remainder is 128 after subtracting 508 from 636.
Include the next digit (4) from the dividend after 128, then repeat: 1284 / 254

Moving on to step 8:
The number 254 fits into 1284 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 83325.0
The remainder is 14 after subtracting 1270 from 1284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
When dividing 140 by 254, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 83325.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
When dividing 1400 by 254, we get 5 with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 83325.05
Deduct 1270 from 1400 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
254 goes into 1300 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 83325.055
If we take 1270 away from 1300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 83325.055, with a leftover of 0.003.
