We're dividing 122170 by 2 
We want to figure out the number of times 122170 can be divided by 2.

Step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Going ahead to step 2:
12 divided by 2 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 0 after subtracting 12 from 12.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Let's proceed to step 3:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Let's proceed to step 4:
If we divide 1 by 2, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 610.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Let's proceed to step 5:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 6108.0
If we subtract 16 from 17, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Let's proceed 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: 61085.0
Subtract 10 from 10 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.

Let's proceed to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61085.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61085.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 61085.0 with a remaining 0.0.
