We're dividing 21539043 by 404 
We want to divide 21539043 by 404.

Going ahead to step 1:
2 divided by 404 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 404

Let's proceed to step 2:
The number 404 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 404

Advancing to step 3:
If we divide 215 by 404, we get 0 and a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Grab the next digit (3) from the dividend, add it to 215, then carry on: 2153 / 404

Advancing to step 4:
2153 divided by 404 is 5 with a remainder of 133.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2020 from 2153 and we're left with 133.
Fetch the next digit (9) from the dividend, attach it to 133 and continue: 1339 / 404

Step 5:
1339 divided by 404 is 3 with a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 127 after subtracting 1212 from 1339.
Include the next digit (0) from the dividend after 127, then repeat: 1270 / 404

Going ahead to step 6:
If we divide 1270 by 404, we get 3 and a remainder of 58.
The next digit of our result is 3. 
Result so far: 533.0
Deduct 1212 from 1270 and we're left with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 404

Moving on to step 7:
404 can be fit into 584 1 times, resulting in a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 5331.0
Subtract 404 from 584 to get 180.
Grab the next digit (3) from the dividend, add it to 180, then carry on: 1803 / 404

Step 8:
404 goes into 1803 4 times with a remainder of 187.
Record the quotient 4 as the next digit in the result. 
Result so far: 53314.0
The remainder is 187 after subtracting 1616 from 1803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 9:
If we divide 1870 by 404, we get 4 and a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 53314.4
If we take 1616 away from 1870, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 10:
When dividing 2540 by 404, we get 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 53314.46
If we subtract 2424 from 2540, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 11:
When dividing 1160 by 404, we get 2 with a remainder of 352.
The next digit of our result is 2. 
Result so far: 53314.462
If we take 808 away from 1160, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 12:
The number 404 fits into 3520 8 times, leaving a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 53314.4628
Deduct 3232 from 3520 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
2880 divided by 404 is 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 53314.46287
Subtracting 2828 from 2880 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
The number 404 fits into 520 1 times, leaving a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 53314.462871
Subtract 404 from 520 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 15:
The number 404 fits into 1160 2 times, leaving a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 53314.4628712
The remainder is 352 after subtracting 808 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
If we divide 3520 by 404, we get 8 and a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 53314.46287128
Subtracting 3232 from 3520 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 53314.46287128, and the remainder is 2.88e-07.
