80863549 ÷ 522 
We want to figure out the number of times 80863549 can be divided by 522.

Going ahead to step 1:
8 divided by 522 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 522

Moving on to step 2:
When dividing 80 by 522, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 522

Moving on to step 3:
The number 522 fits into 808 1 times, leaving a remainder of 286.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 522 from 808 to get 286.
Grab the next digit (6) from the dividend, add it to 286, then carry on: 2866 / 522

Advancing to step 4:
The number 522 fits into 2866 5 times, leaving a remainder of 256.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 256 after subtracting 2610 from 2866.
Include the next digit (3) from the dividend after 256, then repeat: 2563 / 522

Moving on to step 5:
The number 522 fits into 2563 4 times, leaving a remainder of 475.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Deduct 2088 from 2563 and we're left with 475.
Take the next digit (5) from the dividend and append it to 475, then repeat: 4755 / 522

Moving on to step 6:
If we divide 4755 by 522, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 1549.0
If we subtract 4698 from 4755, we get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 522

Going ahead to step 7:
522 goes into 574 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 15491.0
If we subtract 522 from 574, we get 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 522

Moving on to step 8:
If we divide 529 by 522, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 154911.0
Subtract 522 from 529 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 522 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 154911.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 522, we get 1 and a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 154911.01
If we subtract 522 from 700, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 11:
522 can be fit into 1780 3 times, resulting in a remainder of 214.
Use 3 as the next digit of our solution. 
Result so far: 154911.013
If we take 1566 away from 1780, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
When dividing 2140 by 522, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 154911.0134
Subtract 2088 from 2140 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
If we divide 520 by 522, we get 0 and a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 154911.0134
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 14:
The number 522 fits into 5200 9 times, leaving a remainder of 502.
Use 9 as the next digit of our solution. 
Result so far: 154911.013409
The remainder is 502 after subtracting 4698 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 15:
The number 522 fits into 5020 9 times, leaving a remainder of 322.
Write down 9 as next digit of the result. 
Result so far: 154911.0134099
If we subtract 4698 from 5020, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 154911.0134099, and the remainder is 3.22e-06.
