120517 ÷ 1 
We're looking to find how many times 1 goes into 120517.

Advancing to step 1:
1 divided by 1 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

On to step 2:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Let's proceed 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: 1205.0
The remainder is 0 after subtracting 5 from 5.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 5:
When dividing 1 by 1, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 12051.0
Subtract 1 from 1 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 6:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 120517.0
If we subtract 7 from 7, 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.

Moving on to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 120517.0
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.

Let's proceed to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 120517.0
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 120517.0, and the remainder is 0.0.
