We're dividing 10219 by 1 
We want to divide 10219 by 1.

On to step 1:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Step 3:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 2 away from 2, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 4:
1 goes into 1 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1021.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Advancing to step 5:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 10219.0
If we take 9 away from 9, 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.

Let's proceed to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10219.0
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.

Moving on to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10219.0
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 final result is 10219.0 with a remainder of 0.0.
