73509053 ÷ 825 
We want to figure out the number of times 73509053 can be divided by 825.

Advancing to step 1:
825 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 825

Step 2:
73 divided by 825 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 825

On to step 3:
825 can be fit into 735 0 times, resulting in a remainder of 735.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 735 to get 735.
Fetch the next digit (0) from the dividend, attach it to 735 and continue: 7350 / 825

Going ahead to step 4:
825 can be fit into 7350 8 times, resulting in a remainder of 750.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 6600 away from 7350, we end up with 750.
Take the next digit (9) from the dividend and append it to 750, then repeat: 7509 / 825

On to step 5:
7509 divided by 825 is 9 with a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtract 7425 from 7509 to get 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 825

On to step 6:
825 can be fit into 840 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 891.0
Subtract 825 from 840 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 825

Going ahead to step 7:
155 divided by 825 is 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 8910.0
Subtracting 0 from 155 leaves us with 155.
Fetch the next digit (3) from the dividend, attach it to 155 and continue: 1553 / 825

Going ahead to step 8:
If we divide 1553 by 825, we get 1 and a remainder of 728.
Record the quotient 1 as the next digit in the result. 
Result so far: 89101.0
The remainder is 728 after subtracting 825 from 1553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 9:
825 can be fit into 7280 8 times, resulting in a remainder of 680.
Write down 8 as next digit of the result. 
Result so far: 89101.8
If we subtract 6600 from 7280, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
825 goes into 6800 8 times with a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 89101.88
If we subtract 6600 from 6800, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 89101.88, and the remainder is 0.2.
