We divide 210542 by 10
We want to divide 210542 by 10.

On to step 1:
10 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 10

Step 2:
The number 10 fits into 21 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 20 from 21 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 10

Advancing to step 3:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 10 from 10 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 10

On to step 4:
If we divide 5 by 10, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 210.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 10

Moving on to step 5:
10 can be fit into 54 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 2105.0
Subtracting 50 from 54 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 10

Going ahead to step 6:
The number 10 fits into 42 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 21054.0
Subtract 40 from 42 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
10 can be fit into 20 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 21054.2
Subtract 20 from 20 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.

Advancing to step 8:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21054.2
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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21054.2
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 final result is 21054.2 with a remainder of 0.0.
