56520 divided by 1 
The aim is to understand the frequency of 1 in 56520.

Step 1:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

On to step 2:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing to step 3:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 565.0
If we subtract 5 from 5, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Advancing to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 5652.0
Subtract 2 from 2 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 5:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 56520.0
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 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: 56520.0
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.

Moving on to step 7:
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: 56520.0
Subtract 0 from 0 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.

The quotient of the division is 56520.0, and the remainder is 0.0.
