We look at the division of 862029 by 21 
Our goal is to divide 862029 by 21.

Let's proceed to step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 21

Step 2:
21 goes into 86 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 2 after subtracting 84 from 86.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

Step 3:
22 divided by 21 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 41.0
If we take 21 away from 22, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 21

Advancing to step 4:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 21

Advancing to step 5:
102 divided by 21 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4104.0
If we subtract 84 from 102, we get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 21

Moving on to step 6:
When dividing 189 by 21, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 41049.0
The remainder is 0 after subtracting 189 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 41049.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
21 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41049.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 41049.0 and a remainder of 0.0.
