We look at the division of 215030 by 2 
We want to figure out the number of times 215030 can be divided by 2.

Going ahead to step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Advancing to step 2:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Moving on to step 3:
2 goes into 15 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Deduct 14 from 15 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Step 4:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1075.0
If we take 10 away from 10, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Let's proceed to step 5:
If we divide 3 by 2, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 10751.0
If we subtract 2 from 3, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Moving on to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 107515.0
If we subtract 10 from 10, 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 107515.0
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 107515.0
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 107515.0, and the remainder is 0.0.
