We divide 72451993 by 511
Our goal is to divide 72451993 by 511.

Step 1:
If we divide 7 by 511, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 511

Step 2:
72 divided by 511 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 511

On to step 3:
If we divide 724 by 511, we get 1 and a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 511 from 724, we get 213.
Take the next digit (5) from the dividend and append it to 213, then repeat: 2135 / 511

Step 4:
The number 511 fits into 2135 4 times, leaving a remainder of 91.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 91 after subtracting 2044 from 2135.
Grab the next digit (1) from the dividend, add it to 91, then carry on: 911 / 511

Going ahead to step 5:
511 can be fit into 911 1 times, resulting in a remainder of 400.
Write down 1 as next digit of the result. 
Result so far: 141.0
Subtract 511 from 911 to get 400.
Take the next digit (9) from the dividend and append it to 400, then repeat: 4009 / 511

Let's proceed to step 6:
If we divide 4009 by 511, we get 7 and a remainder of 432.
The next digit of our result is 7. 
Result so far: 1417.0
If we take 3577 away from 4009, we end up with 432.
Fetch the next digit (9) from the dividend, attach it to 432 and continue: 4329 / 511

Let's proceed to step 7:
If we divide 4329 by 511, we get 8 and a remainder of 241.
The number 8 becomes the next digit in our result. 
Result so far: 14178.0
Subtract 4088 from 4329 to get 241.
Include the next digit (3) from the dividend after 241, then repeat: 2413 / 511

Let's proceed to step 8:
511 can be fit into 2413 4 times, resulting in a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 141784.0
If we take 2044 away from 2413, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
If we divide 3690 by 511, we get 7 and a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 141784.7
The remainder is 113 after subtracting 3577 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 10:
When dividing 1130 by 511, we get 2 with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 141784.72
Deduct 1022 from 1130 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
If we divide 1080 by 511, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 141784.722
Subtract 1022 from 1080 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 141784.722 with a remaining 0.0058.
