We divide 210293 by 10
We're looking to find how many times 10 goes into 210293.

On to step 1:
10 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Let's proceed to step 2:
The number 10 fits into 21 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 20 from 21, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 10

Let's proceed to step 3:
10 goes into 10 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 10 from 10 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 10

Going ahead to step 4:
10 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 10

Moving on to step 5:
29 divided by 10 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2102.0
If we subtract 20 from 29, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 10

Going ahead to step 6:
When dividing 93 by 10, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 21029.0
If we take 90 away from 93, we end up 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.

Advancing to step 7:
10 goes into 30 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 21029.3
If we take 30 away from 30, 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.

Moving on to step 8:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21029.3
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.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21029.3
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.

The final outcome is 21029.3, with a leftover of 0.0.
