686018 ÷ 5 
The aim is to understand the frequency of 5 in 686018.

On to step 1:
If we divide 6 by 5, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 5

Advancing to step 2:
If we divide 18 by 5, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 15 from 18 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 5

Let's proceed to step 3:
36 divided by 5 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 35 from 36 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 5

Let's proceed to step 4:
10 divided by 5 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 1372.0
If we subtract 10 from 10, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 5

Step 5:
1 divided by 5 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 13720.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

On to step 6:
5 goes into 18 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 137203.0
The remainder is 3 after subtracting 15 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
5 goes into 30 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 137203.6
Deduct 30 from 30 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:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 137203.6
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.

Advancing to step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 137203.6
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.

The quotient of the division is 137203.6, and the remainder is 0.0.
