248797 divided by 21 
Our goal is to divide 248797 by 21.

On 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
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 21

Let's proceed to step 2:
When dividing 24 by 21, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 21 away from 24, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 21

On to step 3:
21 can be fit into 38 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 21 away from 38, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 21

Moving on to step 4:
When dividing 177 by 21, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Deduct 168 from 177 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 21

Advancing to step 5:
If we divide 99 by 21, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1184.0
If we take 84 away from 99, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 21

Let's proceed to step 6:
157 divided by 21 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 11847.0
If we take 147 away from 157, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 11847.4
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 11847.47
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11847.476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11847.4761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 11847.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11847.47619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11847.4761904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 21, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 11847.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 11847.47619047 and a remainder of 1.3e-08.
