We're dividing 21445836 by 100 
Let's see how many times 100 fits into 21445836.

Let's proceed to step 1:
100 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 100

Going ahead to step 2:
100 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 100

Going ahead to step 3:
If we divide 214 by 100, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 200 from 214, we get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 100

Going ahead to step 4:
100 can be fit into 144 1 times, resulting in a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 100 away from 144, we end up with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 100

Step 5:
100 goes into 445 4 times with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we take 400 away from 445, we end up with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 100

Going ahead to step 6:
If we divide 458 by 100, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 2144.0
Subtracting 400 from 458 leaves us with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 100

On to step 7:
583 divided by 100 is 5 with a remainder of 83.
Write down 5 as next digit of the result. 
Result so far: 21445.0
Subtracting 500 from 583 leaves us with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 100

Let's proceed to step 8:
The number 100 fits into 836 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 214458.0
Deduct 800 from 836 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 100 fits into 360 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 214458.3
Subtract 300 from 360 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 100 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 214458.36
Deduct 600 from 600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 100, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 214458.36
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
100 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 214458.36
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 214458.36 with a remaining 0.0.
