We divide 221108 by 21
We're looking to find how many times 21 goes into 221108.

Step 1:
When dividing 2 by 21, we get 0 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.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

Advancing to step 2:
21 goes into 22 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 21 away from 22, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 21

Going ahead to step 3:
When dividing 11 by 21, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 11, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 21

Going ahead to step 4:
The number 21 fits into 111 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we take 105 away from 111, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 21

Step 5:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1052.0
Deduct 42 from 60 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 21

Moving on to step 6:
The number 21 fits into 188 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10528.0
Subtracting 168 from 188 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 10528.9
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10528.95
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 21, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 10528.952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 10528.9523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 10528.95238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10528.95238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 10528.9523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
When dividing 110 by 21, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 10528.95238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 10528.95238095 and a remainder of 5e-09.
