We look at the division of 21898001 by 100 
We're looking to find how many times 100 goes into 21898001.

On to step 1:
When dividing 2 by 100, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our 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

On to step 2:
21 divided by 100 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 100

On to step 3:
If we divide 218 by 100, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 200 away from 218, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 100

On to step 4:
If we divide 189 by 100, we get 1 and a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 100 from 189 to get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 100

Moving on to step 5:
If we divide 898 by 100, we get 8 and a remainder of 98.
The next digit of our result is 8. 
Result so far: 218.0
Subtract 800 from 898 to get 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 100

Moving on to step 6:
100 goes into 980 9 times with a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 2189.0
If we subtract 900 from 980, we get 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 100

Moving on to step 7:
100 can be fit into 800 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 21898.0
The remainder is 0 after subtracting 800 from 800.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 100

Advancing to step 8:
The number 100 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 218980.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 100, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 218980.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 goes into 100 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 218980.01
If we subtract 100 from 100, 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.

Let's proceed to step 11:
0 divided by 100 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 218980.01
Deduct 0 from 0 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 12:
When dividing 0 by 100, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 218980.01
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 218980.01 and a remainder of 0.0.
