Let's divide 414545 by 21
Let's see how many times 21 fits into 414545.

Step 1:
4 divided by 21 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Going ahead to step 2:
41 divided by 21 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 21 from 41, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 21

Let's proceed to step 3:
21 goes into 204 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 189 from 204 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 21

On to step 4:
The number 21 fits into 155 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we subtract 147 from 155, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 21

Advancing to step 5:
21 goes into 84 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
If we subtract 84 from 84, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 21

Let's proceed to step 6:
21 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 19740.0
If we take 0 away from 5, 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.

Moving on to step 7:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 19740.2
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
21 goes into 80 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 19740.23
If we take 63 away from 80, we end up 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.

Step 9:
21 goes into 170 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 19740.238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19740.238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 19740.23809
The remainder is 11 after subtracting 189 from 200.
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 12:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 19740.238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 19740.2380952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 19740.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 19740.23809523 and a remainder of 1.7e-08.
