298558 ÷ 71 
The aim is to understand the frequency of 71 in 298558.

Moving on to step 1:
71 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 71

Advancing to step 2:
29 divided by 71 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 71

Moving on to step 3:
When dividing 298 by 71, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 14 after subtracting 284 from 298.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 71

Moving on to step 4:
71 goes into 145 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 142 from 145 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 71

Let's proceed to step 5:
If we divide 35 by 71, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 71

Step 6:
When dividing 358 by 71, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 4205.0
Deduct 355 from 358 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 7:
When dividing 30 by 71, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4205.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 71 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4205.04
If we take 284 away from 300, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
71 can be fit into 160 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4205.042
Deduct 142 from 160 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 71 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 4205.0422
If we subtract 142 from 180, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 4205.0422 with a remainder of 0.00038.
