507770 ÷ 1 
The aim is to understand the frequency of 1 in 507770.

Advancing to step 1:
If we divide 5 by 1, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 2:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 0, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Advancing to step 3:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 507.0
Subtract 7 from 7 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 4:
If we divide 7 by 1, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5077.0
Deduct 7 from 7 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Step 5:
When dividing 7 by 1, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 50777.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 6:
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: 507770.0
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 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 507770.0
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.

Step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 507770.0
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.

The quotient of the division is 507770.0, and the remainder is 0.0.
