21696720 ÷ 522 
We want to figure out the number of times 21696720 can be divided by 522.

Let's proceed to step 1:
522 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 522

On to step 2:
The number 522 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 522

Going ahead to step 3:
216 divided by 522 is 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Grab the next digit (9) from the dividend, add it to 216, then carry on: 2169 / 522

On to step 4:
The number 522 fits into 2169 4 times, leaving a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2088 from 2169 and we're left with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 522

Step 5:
When dividing 816 by 522, we get 1 with a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 522 from 816 and we're left with 294.
Append the next digit (7) from the dividend to 294 and continue with: 2947 / 522

On to step 6:
The number 522 fits into 2947 5 times, leaving a remainder of 337.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
Subtract 2610 from 2947 to get 337.
Include the next digit (2) from the dividend after 337, then repeat: 3372 / 522

On to step 7:
When dividing 3372 by 522, we get 6 with a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 4156.0
Deduct 3132 from 3372 and we're left with 240.
Fetch the next digit (0) from the dividend, attach it to 240 and continue: 2400 / 522

Let's proceed to step 8:
When dividing 2400 by 522, we get 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 41564.0
If we subtract 2088 from 2400, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 9:
3120 divided by 522 is 5 with a remainder of 510.
Use 5 as the next digit of our solution. 
Result so far: 41564.5
Subtracting 2610 from 3120 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
5100 divided by 522 is 9 with a remainder of 402.
The next digit of our result is 9. 
Result so far: 41564.59
Subtract 4698 from 5100 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 11:
522 goes into 4020 7 times with a remainder of 366.
Record the quotient 7 as the next digit in the result. 
Result so far: 41564.597
The remainder is 366 after subtracting 3654 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 12:
If we divide 3660 by 522, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 41564.5977
Deduct 3654 from 3660 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 41564.5977 with a balance of 6e-05.
