We divide 21863731 by 409
Our goal is to divide 21863731 by 409.

Let's proceed to step 1:
409 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 409

Going ahead to step 2:
If we divide 21 by 409, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 409

On to step 3:
409 can be fit into 218 0 times, resulting in a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 409

Step 4:
2186 divided by 409 is 5 with a remainder of 141.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 141 after subtracting 2045 from 2186.
Fetch the next digit (3) from the dividend, attach it to 141 and continue: 1413 / 409

Going ahead to step 5:
The number 409 fits into 1413 3 times, leaving a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 186 after subtracting 1227 from 1413.
Take the next digit (7) from the dividend and append it to 186, then repeat: 1867 / 409

Going ahead to step 6:
409 goes into 1867 4 times with a remainder of 231.
The next digit of our result is 4. 
Result so far: 534.0
If we take 1636 away from 1867, we end up with 231.
Bring next digit (3) of the dividend behind the 231 and repeat the process: 2313 / 409

Step 7:
The number 409 fits into 2313 5 times, leaving a remainder of 268.
Put 5 as the next digit of the answer. 
Result so far: 5345.0
If we take 2045 away from 2313, we end up with 268.
Append the next digit (1) from the dividend to 268 and continue with: 2681 / 409

Let's proceed to step 8:
409 can be fit into 2681 6 times, resulting in a remainder of 227.
The number 6 becomes the next digit in our result. 
Result so far: 53456.0
The remainder is 227 after subtracting 2454 from 2681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
If we divide 2270 by 409, we get 5 and a remainder of 225.
The next digit of our result is 5. 
Result so far: 53456.5
Subtracting 2045 from 2270 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 10:
The number 409 fits into 2250 5 times, leaving a remainder of 205.
The next digit of our result is 5. 
Result so far: 53456.55
If we take 2045 away from 2250, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 53456.55, with a leftover of 0.205.
