Let's divide 514158 by 21
Our goal is to divide 514158 by 21.

Moving on to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 21

On to step 2:
When dividing 51 by 21, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 9 after subtracting 42 from 51.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 21

Let's proceed to step 3:
21 can be fit into 94 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 10 after subtracting 84 from 94.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 21

Let's proceed to step 4:
If we divide 101 by 21, we get 4 and a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Deduct 84 from 101 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 21

Advancing to step 5:
If we divide 175 by 21, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 2448.0
Deduct 168 from 175 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 21

Moving on to step 6:
The number 21 fits into 78 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 24483.0
If we subtract 63 from 78, 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.

Moving on to step 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 24483.7
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.

Step 8:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 24483.71
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.

Advancing to step 9:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 24483.714
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.

On to step 10:
60 divided by 21 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 24483.7142
Deduct 42 from 60 and we're left 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 11:
If we divide 180 by 21, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 24483.71428
If we take 168 away from 180, we end up 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.

Step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 24483.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 24483.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 24483.71428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 24483.71428571, with a leftover of 9e-09.
