57586728 divided by 5 
The aim is to understand the frequency of 5 in 57586728.

Let's proceed to step 1:
The number 5 fits into 5 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 5 from 5, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

Advancing to step 2:
If we divide 7 by 5, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 5 from 7 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 5

Advancing to step 3:
5 can be fit into 25 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 25 from 25, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 5

Step 4:
5 can be fit into 8 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1151.0
Subtracting 5 from 8 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 5

Going ahead to step 5:
5 can be fit into 36 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 11517.0
If we subtract 35 from 36, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 5

Step 6:
The number 5 fits into 17 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 115173.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 5

Going ahead to step 7:
5 goes into 22 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1151734.0
The remainder is 2 after subtracting 20 from 22.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 5

Moving on to step 8:
The number 5 fits into 28 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 11517345.0
Deduct 25 from 28 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 5 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 11517345.6
If we subtract 30 from 30, 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.

Step 10:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11517345.6
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.

Let's proceed to step 11:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11517345.6
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 11517345.6, and the remainder is 0.0.
