21426461 ÷ 497 
Let's see how many times 497 fits into 21426461.

On to step 1:
If we divide 2 by 497, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 497

Advancing to step 2:
497 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 497

Advancing to step 3:
When dividing 214 by 497, we get 0 with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 497

On to step 4:
The number 497 fits into 2142 4 times, leaving a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1988 away from 2142, we end up with 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 497

Step 5:
497 goes into 1546 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 1491 from 1546 leaves us with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 497

Advancing to step 6:
If we divide 554 by 497, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 431.0
If we take 497 away from 554, we end up with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 497

Moving on to step 7:
576 divided by 497 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 4311.0
The remainder is 79 after subtracting 497 from 576.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 497

Let's proceed to step 8:
When dividing 791 by 497, we get 1 with a remainder of 294.
Use 1 as the next digit of our solution. 
Result so far: 43111.0
If we take 497 away from 791, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 9:
When dividing 2940 by 497, we get 5 with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 43111.5
The remainder is 455 after subtracting 2485 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 10:
497 can be fit into 4550 9 times, resulting in a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 43111.59
If we subtract 4473 from 4550, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
497 goes into 770 1 times with a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 43111.591
If we take 497 away from 770, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 12:
497 can be fit into 2730 5 times, resulting in a remainder of 245.
The next digit of our result is 5. 
Result so far: 43111.5915
Subtracting 2485 from 2730 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 13:
497 goes into 2450 4 times with a remainder of 462.
Put 4 as the next digit of the answer. 
Result so far: 43111.59154
If we take 1988 away from 2450, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 14:
When dividing 4620 by 497, we get 9 with a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 43111.591549
The remainder is 147 after subtracting 4473 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 15:
The number 497 fits into 1470 2 times, leaving a remainder of 476.
Use 2 as the next digit of our solution. 
Result so far: 43111.5915492
The remainder is 476 after subtracting 994 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 16:
497 can be fit into 4760 9 times, resulting in a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 43111.59154929
If we subtract 4473 from 4760, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

After the division, we end up with 43111.59154929 and a remainder of 2.87e-07.
