Let's divide 17908710 by 250
The aim is to understand the frequency of 250 in 17908710.

Going ahead to step 1:
250 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 250

Going ahead to step 2:
The number 250 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 250

Let's proceed to step 3:
The number 250 fits into 179 0 times, leaving a remainder of 179.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 179 and we're left with 179.
Bring next digit (0) of the dividend behind the 179 and repeat the process: 1790 / 250

Going ahead to step 4:
When dividing 1790 by 250, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 1750 from 1790 leaves us with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 250

Let's proceed to step 5:
408 divided by 250 is 1 with a remainder of 158.
The next digit of our result is 1. 
Result so far: 71.0
Deduct 250 from 408 and we're left with 158.
Bring next digit (7) of the dividend behind the 158 and repeat the process: 1587 / 250

Advancing to step 6:
250 can be fit into 1587 6 times, resulting in a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 716.0
Subtract 1500 from 1587 to get 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 250

Step 7:
When dividing 871 by 250, we get 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 7163.0
If we subtract 750 from 871, we get 121.
Grab the next digit (0) from the dividend, add it to 121, then carry on: 1210 / 250

Advancing to step 8:
If we divide 1210 by 250, we get 4 and a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 71634.0
Subtracting 1000 from 1210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
When dividing 2100 by 250, we get 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 71634.8
Subtracting 2000 from 2100 leaves us 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.

Step 10:
250 goes into 1000 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 71634.84
Subtract 1000 from 1000 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.

On to step 11:
250 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 71634.84
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.

Going ahead to step 12:
250 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 71634.84
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.

After the division, we end up with 71634.84 and a remainder of 0.0.
