520187 ÷ 5 
The aim is to understand the frequency of 5 in 520187.

Moving on to step 1:
When dividing 5 by 5, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 5 from 5, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 5

Moving on to step 2:
When dividing 2 by 5, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 5

Advancing to step 3:
5 can be fit into 20 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Deduct 20 from 20 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Going ahead to step 4:
If we divide 1 by 5, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 1040.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

Advancing to step 5:
If we divide 18 by 5, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 10403.0
If we subtract 15 from 18, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 5

Moving on to step 6:
5 goes into 37 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 104037.0
If we subtract 35 from 37, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 5 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 104037.4
Deduct 20 from 20 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.

On to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 104037.4
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.

Advancing to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 104037.4
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.

In conclusion, the division gives 104037.4 with a balance of 0.0.
