247838 divided by 21 
We want to divide 247838 by 21.

Going ahead to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 21

Advancing to step 2:
When dividing 24 by 21, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 21 away from 24, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 21

Going ahead to step 3:
The number 21 fits into 37 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 16 after subtracting 21 from 37.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 21

Step 4:
21 goes into 168 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtract 168 from 168 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

On to step 5:
If we divide 3 by 21, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Moving on to step 6:
38 divided by 21 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11801.0
Deduct 21 from 38 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 7:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 11801.8
If we subtract 168 from 170, we 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.

Advancing to step 8:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11801.8
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.

Let's proceed to step 9:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 11801.809
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.

On to step 10:
If we divide 110 by 21, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11801.8095
Subtracting 105 from 110 leaves us 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.

Step 11:
If we divide 50 by 21, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11801.80952
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 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 11801.809523
Subtracting 63 from 80 leaves us 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.

On to step 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 11801.8095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11801.8095238
If we take 0 away from 20, we end up 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.

Our division results in 11801.8095238 with a remaining 2e-08.
