We look at the division of 590238 by 71 
The aim is to understand the frequency of 71 in 590238.

Moving on to step 1:
The number 71 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 71

Let's proceed to step 2:
71 goes into 59 0 times with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 71

Step 3:
When dividing 590 by 71, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 8.0
If we take 568 away from 590, we end up with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 71

Moving on to step 4:
If we divide 222 by 71, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 213 from 222 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 71

Let's proceed to step 5:
If we divide 93 by 71, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 831.0
The remainder is 22 after subtracting 71 from 93.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 71

Going ahead to step 6:
If we divide 228 by 71, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 8313.0
If we take 213 away from 228, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
71 goes into 150 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8313.2
If we subtract 142 from 150, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
71 can be fit into 80 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 8313.21
If we take 71 away from 80, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
71 can be fit into 90 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 8313.211
Subtract 71 from 90 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 8313.211, and the remainder is 0.0019.
