We look at the division of 21127760 by 522 
We want to divide 21127760 by 522.

Let's proceed to step 1:
The number 522 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 522

Advancing to step 2:
If we divide 21 by 522, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 522

Going ahead to step 3:
The number 522 fits into 211 0 times, leaving a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Fetch the next digit (2) from the dividend, attach it to 211 and continue: 2112 / 522

Step 4:
2112 divided by 522 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2088 from 2112 leaves us with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 522

On to step 5:
247 divided by 522 is 0 with a remainder of 247.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 247 leaves us with 247.
Append the next digit (7) from the dividend to 247 and continue with: 2477 / 522

Step 6:
522 can be fit into 2477 4 times, resulting in a remainder of 389.
The next digit of our result is 4. 
Result so far: 404.0
If we take 2088 away from 2477, we end up with 389.
Grab the next digit (6) from the dividend, add it to 389, then carry on: 3896 / 522

Step 7:
When dividing 3896 by 522, we get 7 with a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 4047.0
If we subtract 3654 from 3896, we get 242.
Bring next digit (0) of the dividend behind the 242 and repeat the process: 2420 / 522

Let's proceed to step 8:
When dividing 2420 by 522, we get 4 with a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 40474.0
Subtracting 2088 from 2420 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
When dividing 3320 by 522, we get 6 with a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 40474.6
Subtracting 3132 from 3320 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
If we divide 1880 by 522, we get 3 and a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 40474.63
If we take 1566 away from 1880, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
522 goes into 3140 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 40474.636
The remainder is 8 after subtracting 3132 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
80 divided by 522 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 40474.636
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
If we divide 800 by 522, we get 1 and a remainder of 278.
The number 1 becomes the next digit in our result. 
Result so far: 40474.63601
The remainder is 278 after subtracting 522 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 14:
522 goes into 2780 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 40474.636015
Deduct 2610 from 2780 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 15:
522 can be fit into 1700 3 times, resulting in a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 40474.6360153
Subtracting 1566 from 1700 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 16:
522 can be fit into 1340 2 times, resulting in a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 40474.63601532
Subtracting 1044 from 1340 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 40474.63601532 with a remainder of 2.96e-07.
