Let's divide 248202 by 21
Let's see how many times 21 fits into 248202.

Advancing to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 21

Let's proceed to step 2:
If we divide 24 by 21, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 21 from 24 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 21

Going ahead to step 3:
21 goes into 38 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 21 away from 38, we end up with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 21

Advancing to step 4:
21 goes into 172 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 168 from 172 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 21

Let's proceed to step 5:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1181.0
Subtracting 21 from 40 leaves us with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 21

Going ahead to step 6:
If we divide 192 by 21, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 11819.0
The remainder is 3 after subtracting 189 from 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 11819.1
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 11819.14
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 11819.142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11819.1428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11819.14285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 11819.142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 21 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11819.1428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 11819.14285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 11819.14285714 with a remainder of 6e-09.
