Let's divide 21862345 by 488
We're looking to find how many times 488 goes into 21862345.

On to step 1:
When dividing 2 by 488, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 488

Moving on to step 2:
488 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 488

On to step 3:
If we divide 218 by 488, we get 0 and a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Take the next digit (6) from the dividend and append it to 218, then repeat: 2186 / 488

Moving on to step 4:
The number 488 fits into 2186 4 times, leaving a remainder of 234.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1952 from 2186 to get 234.
Grab the next digit (2) from the dividend, add it to 234, then carry on: 2342 / 488

Advancing to step 5:
The number 488 fits into 2342 4 times, leaving a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 1952 from 2342 and we're left with 390.
Append the next digit (3) from the dividend to 390 and continue with: 3903 / 488

Moving on to step 6:
When dividing 3903 by 488, we get 7 with a remainder of 487.
Write down 7 as next digit of the result. 
Result so far: 447.0
If we take 3416 away from 3903, we end up with 487.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 488

On to step 7:
488 can be fit into 4874 9 times, resulting in a remainder of 482.
Record the quotient 9 as the next digit in the result. 
Result so far: 4479.0
If we take 4392 away from 4874, we end up with 482.
Bring next digit (5) of the dividend behind the 482 and repeat the process: 4825 / 488

Let's proceed to step 8:
488 goes into 4825 9 times with a remainder of 433.
Use 9 as the next digit of our solution. 
Result so far: 44799.0
If we take 4392 away from 4825, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 9:
If we divide 4330 by 488, we get 8 and a remainder of 426.
Record the quotient 8 as the next digit in the result. 
Result so far: 44799.8
Subtract 3904 from 4330 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 10:
4260 divided by 488 is 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 44799.88
Subtract 3904 from 4260 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final result is 44799.88 with a remainder of 0.356.
