Let's divide 21642793 by 491
We're looking to find how many times 491 goes into 21642793.

Moving on to step 1:
491 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 491

Moving on to step 2:
491 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 491

On to step 3:
216 divided by 491 is 0 with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Take the next digit (4) from the dividend and append it to 216, then repeat: 2164 / 491

Going ahead to step 4:
When dividing 2164 by 491, we get 4 with a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1964 from 2164 and we're left with 200.
Grab the next digit (2) from the dividend, add it to 200, then carry on: 2002 / 491

Advancing to step 5:
The number 491 fits into 2002 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 1964 from 2002 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 491

Advancing to step 6:
The number 491 fits into 387 0 times, leaving a remainder of 387.
The next digit of our result is 0. 
Result so far: 440.0
The remainder is 387 after subtracting 0 from 387.
Include the next digit (9) from the dividend after 387, then repeat: 3879 / 491

Advancing to step 7:
491 goes into 3879 7 times with a remainder of 442.
Write down 7 as next digit of the result. 
Result so far: 4407.0
Subtract 3437 from 3879 to get 442.
Take the next digit (3) from the dividend and append it to 442, then repeat: 4423 / 491

On to step 8:
491 goes into 4423 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 44079.0
If we take 4419 away from 4423, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
491 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 44079.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
491 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 44079.0
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 44079.0 with a remaining 0.4.
