We look at the division of 99151719 by 250 
Our goal is to divide 99151719 by 250.

On to step 1:
The number 250 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 250

Going ahead to step 2:
The number 250 fits into 99 0 times, leaving a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 250

Step 3:
250 goes into 991 3 times with a remainder of 241.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 241 after subtracting 750 from 991.
Grab the next digit (5) from the dividend, add it to 241, then carry on: 2415 / 250

Step 4:
If we divide 2415 by 250, we get 9 and a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 2250 away from 2415, we end up with 165.
Bring next digit (1) of the dividend behind the 165 and repeat the process: 1651 / 250

Moving on to step 5:
250 goes into 1651 6 times with a remainder of 151.
Put 6 as the next digit of the answer. 
Result so far: 396.0
If we subtract 1500 from 1651, we get 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 250

Going ahead to step 6:
The number 250 fits into 1517 6 times, leaving a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 3966.0
Subtract 1500 from 1517 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 250

Step 7:
If we divide 171 by 250, we get 0 and a remainder of 171.
Use 0 as the next digit of our solution. 
Result so far: 39660.0
The remainder is 171 after subtracting 0 from 171.
Include the next digit (9) from the dividend after 171, then repeat: 1719 / 250

Moving on to step 8:
If we divide 1719 by 250, we get 6 and a remainder of 219.
Write down 6 as next digit of the result. 
Result so far: 396606.0
Subtracting 1500 from 1719 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 9:
The number 250 fits into 2190 8 times, leaving a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 396606.8
The remainder is 190 after subtracting 2000 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
The number 250 fits into 1900 7 times, leaving a remainder of 150.
Use 7 as the next digit of our solution. 
Result so far: 396606.87
The remainder is 150 after subtracting 1750 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
250 goes into 1500 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 396606.876
Deduct 1500 from 1500 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 12:
If we divide 0 by 250, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 396606.876
If we take 0 away from 0, 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.

On to step 13:
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: 396606.876
If we take 0 away from 0, 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.

After the division, we end up with 396606.876 and a remainder of 0.0.
