We're dividing 246455 by 21 
We want to divide 246455 by 21.

Advancing to step 1:
2 divided by 21 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 21

Step 2:
24 divided by 21 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 21 from 24 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 21

Step 3:
If we divide 36 by 21, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 21 from 36 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

Advancing to step 4:
154 divided by 21 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 147 from 154 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 21

Going ahead to step 5:
21 can be fit into 75 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
Subtract 63 from 75 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 21

Moving on to step 6:
21 can be fit into 125 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 11735.0
If we subtract 105 from 125, 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 7:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 11735.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 11735.95
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 9:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 11735.952
Subtracting 42 from 50 leaves us 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.

Step 10:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 11735.9523
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:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 11735.95238
If we take 168 away from 170, we end up 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 12:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11735.95238
Subtract 0 from 20 to 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.

Step 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 11735.9523809
If we subtract 189 from 200, we get 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 14:
When dividing 110 by 21, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11735.95238095
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.

The quotient of the division is 11735.95238095, and the remainder is 5e-09.
