We're dividing 119910 by 21 
We want to divide 119910 by 21.

On to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 21

Advancing to step 2:
21 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 21

Let's proceed to step 3:
21 can be fit into 119 5 times, resulting in a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 14 after subtracting 105 from 119.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 21

Advancing to step 4:
The number 21 fits into 149 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 147 from 149 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 21

Going ahead to step 5:
21 divided by 21 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 571.0
The remainder is 0 after subtracting 21 from 21.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 21

On to step 6:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5710.0
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.

On to step 7:
If we divide 0 by 21, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5710.0
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.

Moving on to 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: 5710.0
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.

After the division, we end up with 5710.0 and a remainder of 0.0.
