We're dividing 21555818 by 497 
We want to divide 21555818 by 497.

Let's proceed to step 1:
2 divided by 497 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 497

Going ahead to step 2:
21 divided by 497 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 497

Going ahead to step 3:
When dividing 215 by 497, we get 0 with a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Take the next digit (5) from the dividend and append it to 215, then repeat: 2155 / 497

Step 4:
If we divide 2155 by 497, we get 4 and a remainder of 167.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1988 from 2155 to get 167.
Include the next digit (5) from the dividend after 167, then repeat: 1675 / 497

Let's proceed to step 5:
The number 497 fits into 1675 3 times, leaving a remainder of 184.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 1491 from 1675 leaves us with 184.
Grab the next digit (8) from the dividend, add it to 184, then carry on: 1848 / 497

Advancing to step 6:
497 can be fit into 1848 3 times, resulting in a remainder of 357.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Subtract 1491 from 1848 to get 357.
Append the next digit (1) from the dividend to 357 and continue with: 3571 / 497

Let's proceed to step 7:
497 goes into 3571 7 times with a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 4337.0
Subtracting 3479 from 3571 leaves us with 92.
Grab the next digit (8) from the dividend, add it to 92, then carry on: 928 / 497

Let's proceed to step 8:
If we divide 928 by 497, we get 1 and a remainder of 431.
The number 1 becomes the next digit in our result. 
Result so far: 43371.0
Subtracting 497 from 928 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 9:
4310 divided by 497 is 8 with a remainder of 334.
Write down 8 as next digit of the result. 
Result so far: 43371.8
Subtracting 3976 from 4310 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 10:
When dividing 3340 by 497, we get 6 with a remainder of 358.
Use 6 as the next digit of our solution. 
Result so far: 43371.86
If we take 2982 away from 3340, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 11:
497 goes into 3580 7 times with a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 43371.867
Subtracting 3479 from 3580 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 12:
The number 497 fits into 1010 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 43371.8672
If we take 994 away from 1010, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
497 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 43371.8672
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
The number 497 fits into 1600 3 times, leaving a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 43371.867203
Deduct 1491 from 1600 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 15:
1090 divided by 497 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 43371.8672032
Subtract 994 from 1090 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
497 goes into 960 1 times with a remainder of 463.
Use 1 as the next digit of our solution. 
Result so far: 43371.86720321
If we subtract 497 from 960, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

The final result is 43371.86720321 with a remainder of 4.63e-07.
