Let's divide 91919170 by 250
The aim is to understand the frequency of 250 in 91919170.

Step 1:
When dividing 9 by 250, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 250

Let's proceed to step 2:
250 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (9) from the dividend and append it to 91, then repeat: 919 / 250

Step 3:
250 can be fit into 919 3 times, resulting in a remainder of 169.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 750 from 919, we get 169.
Include the next digit (1) from the dividend after 169, then repeat: 1691 / 250

Advancing to step 4:
When dividing 1691 by 250, we get 6 with a remainder of 191.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 1500 away from 1691, we end up with 191.
Take the next digit (9) from the dividend and append it to 191, then repeat: 1919 / 250

Let's proceed to step 5:
If we divide 1919 by 250, we get 7 and a remainder of 169.
Put 7 as the next digit of the answer. 
Result so far: 367.0
Subtract 1750 from 1919 to get 169.
Bring next digit (1) of the dividend behind the 169 and repeat the process: 1691 / 250

Advancing to step 6:
250 goes into 1691 6 times with a remainder of 191.
The number 6 becomes the next digit in our result. 
Result so far: 3676.0
Deduct 1500 from 1691 and we're left with 191.
Append the next digit (7) from the dividend to 191 and continue with: 1917 / 250

Advancing to step 7:
1917 divided by 250 is 7 with a remainder of 167.
The next digit of our result is 7. 
Result so far: 36767.0
If we take 1750 away from 1917, we end up with 167.
Fetch the next digit (0) from the dividend, attach it to 167 and continue: 1670 / 250

Moving on to step 8:
When dividing 1670 by 250, we get 6 with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 367676.0
Subtracting 1500 from 1670 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
The number 250 fits into 1700 6 times, leaving a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 367676.6
Subtracting 1500 from 1700 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
When dividing 2000 by 250, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 367676.68
If we subtract 2000 from 2000, 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.

Step 11:
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: 367676.68
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.

Moving on to step 12:
0 divided by 250 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 367676.68
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 367676.68 and a remainder of 0.0.
