We're dividing 371590 by 5 
The aim is to understand the frequency of 5 in 371590.

Moving on to step 1:
When dividing 3 by 5, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 5

Advancing to step 2:
5 goes into 37 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 35 away from 37, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

On to step 3:
21 divided by 5 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 20 from 21 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 5

Step 4:
5 can be fit into 15 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 743.0
If we subtract 15 from 15, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 5

Let's proceed to step 5:
5 can be fit into 9 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 7431.0
If we subtract 5 from 9, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 5

Advancing to step 6:
40 divided by 5 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 74318.0
Deduct 40 from 40 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.

Moving on to step 7:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 74318.0
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 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74318.0
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.

In conclusion, the division gives 74318.0 with a balance of 0.0.
