We look at the division of 87289406 by 250 
The aim is to understand the frequency of 250 in 87289406.

Advancing to step 1:
The number 250 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 250

Let's proceed to step 2:
The number 250 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 250

Step 3:
The number 250 fits into 872 3 times, leaving a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 750 from 872, we get 122.
Append the next digit (8) from the dividend to 122 and continue with: 1228 / 250

Going ahead to step 4:
250 goes into 1228 4 times with a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 1000 away from 1228, we end up with 228.
Include the next digit (9) from the dividend after 228, then repeat: 2289 / 250

On to step 5:
2289 divided by 250 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 349.0
If we take 2250 away from 2289, we end up with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 250

On to step 6:
250 can be fit into 394 1 times, resulting in a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 3491.0
The remainder is 144 after subtracting 250 from 394.
Include the next digit (0) from the dividend after 144, then repeat: 1440 / 250

On to step 7:
250 goes into 1440 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 34915.0
Subtracting 1250 from 1440 leaves us with 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 250

Advancing to step 8:
The number 250 fits into 1906 7 times, leaving a remainder of 156.
The next digit of our result is 7. 
Result so far: 349157.0
The remainder is 156 after subtracting 1750 from 1906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 9:
When dividing 1560 by 250, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 349157.6
Deduct 1500 from 1560 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
The number 250 fits into 600 2 times, leaving a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 349157.62
Deduct 500 from 600 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
When dividing 1000 by 250, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 349157.624
Deduct 1000 from 1000 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.

Advancing to step 12:
250 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 349157.624
Subtract 0 from 0 to 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 13:
If we divide 0 by 250, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 349157.624
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 final outcome is 349157.624, with a leftover of 0.0.
