We're dividing 17135149 by 250 
The aim is to understand the frequency of 250 in 17135149.

Let's proceed to step 1:
If we divide 1 by 250, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 250

Advancing to step 2:
If we divide 17 by 250, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 250

Moving on to step 3:
When dividing 171 by 250, we get 0 with a remainder of 171.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 171 and we're left with 171.
Grab the next digit (3) from the dividend, add it to 171, then carry on: 1713 / 250

Step 4:
250 goes into 1713 6 times with a remainder of 213.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 213 after subtracting 1500 from 1713.
Grab the next digit (5) from the dividend, add it to 213, then carry on: 2135 / 250

On to step 5:
250 goes into 2135 8 times with a remainder of 135.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 2000 from 2135, we get 135.
Include the next digit (1) from the dividend after 135, then repeat: 1351 / 250

Advancing to step 6:
250 can be fit into 1351 5 times, resulting in a remainder of 101.
The next digit of our result is 5. 
Result so far: 685.0
If we take 1250 away from 1351, we end up with 101.
Include the next digit (4) from the dividend after 101, then repeat: 1014 / 250

Going ahead to step 7:
250 can be fit into 1014 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 6854.0
Subtract 1000 from 1014 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 250

Let's proceed to step 8:
250 goes into 149 0 times with a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 68540.0
Subtract 0 from 149 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
250 can be fit into 1490 5 times, resulting in a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 68540.5
Subtract 1250 from 1490 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
The number 250 fits into 2400 9 times, leaving a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 68540.59
If we subtract 2250 from 2400, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
1500 divided by 250 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 68540.596
If we take 1500 away from 1500, we end up 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.

Step 12:
When dividing 0 by 250, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 68540.596
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.

Step 13:
250 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 68540.596
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.

The final result is 68540.596 with a remainder of 0.0.
