Let's divide 79897028 by 250
The aim is to understand the frequency of 250 in 79897028.

Advancing to step 1:
The number 250 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 250

Let's proceed to step 2:
When dividing 79 by 250, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 250

Step 3:
798 divided by 250 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 750 away from 798, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 250

Going ahead to step 4:
250 can be fit into 489 1 times, resulting in a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 250 from 489 to get 239.
Fetch the next digit (7) from the dividend, attach it to 239 and continue: 2397 / 250

Moving on to step 5:
250 goes into 2397 9 times with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 319.0
Deduct 2250 from 2397 and we're left with 147.
Include the next digit (0) from the dividend after 147, then repeat: 1470 / 250

On to step 6:
250 goes into 1470 5 times with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 3195.0
If we subtract 1250 from 1470, we get 220.
Fetch the next digit (2) from the dividend, attach it to 220 and continue: 2202 / 250

Going ahead to step 7:
250 can be fit into 2202 8 times, resulting in a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 31958.0
If we take 2000 away from 2202, we end up with 202.
Grab the next digit (8) from the dividend, add it to 202, then carry on: 2028 / 250

Going ahead to step 8:
2028 divided by 250 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 319588.0
Deduct 2000 from 2028 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 250 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 319588.1
Subtract 250 from 280 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 250 fits into 300 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 319588.11
Deduct 250 from 300 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 319588.11, with a leftover of 0.05.
