21910258 ÷ 250 
We want to figure out the number of times 21910258 can be divided by 250.

On to step 1:
250 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 250

On to step 2:
When dividing 21 by 250, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 250

Advancing to step 3:
When dividing 219 by 250, we get 0 with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Grab the next digit (1) from the dividend, add it to 219, then carry on: 2191 / 250

Advancing to step 4:
250 can be fit into 2191 8 times, resulting in a remainder of 191.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 2000 from 2191, we get 191.
Fetch the next digit (0) from the dividend, attach it to 191 and continue: 1910 / 250

Going ahead to step 5:
The number 250 fits into 1910 7 times, leaving a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 160 after subtracting 1750 from 1910.
Bring next digit (2) of the dividend behind the 160 and repeat the process: 1602 / 250

Moving on to step 6:
The number 250 fits into 1602 6 times, leaving a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 876.0
Subtract 1500 from 1602 to get 102.
Grab the next digit (5) from the dividend, add it to 102, then carry on: 1025 / 250

Let's proceed to step 7:
The number 250 fits into 1025 4 times, leaving a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 8764.0
Subtract 1000 from 1025 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 250

Moving on to step 8:
When dividing 258 by 250, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 87641.0
If we subtract 250 from 258, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 250, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 87641.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 250, we get 3 and a remainder of 50.
The next digit of our result is 3. 
Result so far: 87641.03
Subtracting 750 from 800 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
250 goes into 500 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 87641.032
Subtracting 500 from 500 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.

On 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: 87641.032
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:
If we divide 0 by 250, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 87641.032
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.

The final result is 87641.032 with a remainder of 0.0.
