Let's divide 210570 by 1
Our goal is to divide 210570 by 1.

Let's proceed to step 1:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 2 from 2, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Moving on to step 2:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 3:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Advancing to step 4:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2105.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Step 5:
7 divided by 1 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 21057.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 6:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 210570.0
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:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 210570.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 210570.0
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.

The quotient of the division is 210570.0, and the remainder is 0.0.
