Let's divide 879060 by 21
We want to figure out the number of times 879060 can be divided by 21.

Moving on to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Advancing to step 2:
If we divide 87 by 21, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 84 from 87, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 21

On to step 3:
39 divided by 21 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 21 away from 39, we end up with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 21

Moving on to step 4:
21 goes into 180 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 418.0
Subtract 168 from 180 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 21

On to step 5:
21 can be fit into 126 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 4186.0
Deduct 126 from 126 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 21

Step 6:
If we divide 0 by 21, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41860.0
If we subtract 0 from 0, we 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.

Going ahead to step 7:
When dividing 0 by 21, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41860.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
If we divide 0 by 21, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41860.0
If we take 0 away from 0, we end up 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.

The quotient of the division is 41860.0, and the remainder is 0.0.
