248632 ÷ 21 
We're looking to find how many times 21 goes into 248632.

Moving on 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
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 21

Going ahead to step 2:
If we divide 24 by 21, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 21 from 24 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 21

Let's proceed to step 3:
The number 21 fits into 38 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 21 from 38 to get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 21

Advancing to step 4:
If we divide 176 by 21, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
The remainder is 8 after subtracting 168 from 176.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 21

Advancing to step 5:
When dividing 83 by 21, we get 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 1183.0
Subtract 63 from 83 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 21

Going ahead to step 6:
21 can be fit into 202 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 11839.0
Subtract 189 from 202 to 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.

Advancing to step 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 11839.6
Subtract 126 from 130 to 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.

Let's proceed to step 8:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 11839.61
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.

Going ahead to step 9:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11839.619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11839.619
Subtracting 0 from 10 leaves us 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 11:
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: 11839.61904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
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: 11839.619047
Deduct 147 from 160 and we're left 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.

Step 13:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 11839.6190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 11839.61904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 11839.61904761, and the remainder is 1.9e-08.
