We divide 21724793 by 409
We want to divide 21724793 by 409.

Let's proceed to step 1:
409 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 409

Let's proceed to step 2:
If we divide 21 by 409, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 409

Moving on to step 3:
When dividing 217 by 409, we get 0 with a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Grab the next digit (2) from the dividend, add it to 217, then carry on: 2172 / 409

Let's proceed to step 4:
2172 divided by 409 is 5 with a remainder of 127.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2045 from 2172 and we're left with 127.
Append the next digit (4) from the dividend to 127 and continue with: 1274 / 409

Going ahead to step 5:
The number 409 fits into 1274 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 1227 from 1274 leaves us with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 409

Advancing to step 6:
477 divided by 409 is 1 with a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 531.0
Subtract 409 from 477 to get 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 409

On to step 7:
When dividing 689 by 409, we get 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 5311.0
The remainder is 280 after subtracting 409 from 689.
Append the next digit (3) from the dividend to 280 and continue with: 2803 / 409

Moving on to step 8:
If we divide 2803 by 409, we get 6 and a remainder of 349.
Write down 6 as next digit of the result. 
Result so far: 53116.0
The remainder is 349 after subtracting 2454 from 2803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 9:
If we divide 3490 by 409, we get 8 and a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 53116.8
Subtracting 3272 from 3490 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
If we divide 2180 by 409, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 53116.85
The remainder is 135 after subtracting 2045 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
When dividing 1350 by 409, we get 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 53116.853
Subtracting 1227 from 1350 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 12:
If we divide 1230 by 409, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 53116.8533
The remainder is 3 after subtracting 1227 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 53116.8533 with a remainder of 3e-05.
