We're dividing 21527321 by 100 
We're looking to find how many times 100 goes into 21527321.

Step 1:
100 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 100

Advancing to step 2:
The number 100 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 100

Advancing to step 3:
100 goes into 215 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 15 after subtracting 200 from 215.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 100

Going ahead to step 4:
152 divided by 100 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 100 away from 152, we end up with 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 100

Let's proceed to step 5:
100 goes into 527 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtracting 500 from 527 leaves us with 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 100

Advancing to step 6:
If we divide 273 by 100, we get 2 and a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 2152.0
Deduct 200 from 273 and we're left with 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 100

Advancing to step 7:
The number 100 fits into 732 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 21527.0
The remainder is 32 after subtracting 700 from 732.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 100

On to step 8:
100 can be fit into 321 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 215273.0
Deduct 300 from 321 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 100, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 215273.2
If we take 200 away from 210, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 100, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 215273.21
Deduct 100 from 100 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.

Going ahead to step 11:
100 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 215273.21
Subtracting 0 from 0 leaves us 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 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: 215273.21
Subtract 0 from 0 to 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.

After the division, we end up with 215273.21 and a remainder of 0.0.
