72550989 ÷ 512 
Let's see how many times 512 fits into 72550989.

On to step 1:
512 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 512

Advancing to step 2:
The number 512 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 512

Advancing to step 3:
512 can be fit into 725 1 times, resulting in a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 512 from 725 leaves us with 213.
Grab the next digit (5) from the dividend, add it to 213, then carry on: 2135 / 512

Going ahead to step 4:
512 goes into 2135 4 times with a remainder of 87.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2048 from 2135 to get 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 512

Going ahead to step 5:
870 divided by 512 is 1 with a remainder of 358.
The next digit of our result is 1. 
Result so far: 141.0
The remainder is 358 after subtracting 512 from 870.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 512

Step 6:
512 can be fit into 3589 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1417.0
Subtracting 3584 from 3589 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 512

Let's proceed to step 7:
58 divided by 512 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 14170.0
Subtracting 0 from 58 leaves us with 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 512

Step 8:
512 goes into 589 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 141701.0
Deduct 512 from 589 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
512 can be fit into 770 1 times, resulting in a remainder of 258.
Use 1 as the next digit of our solution. 
Result so far: 141701.1
The remainder is 258 after subtracting 512 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
512 goes into 2580 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 141701.15
Deduct 2560 from 2580 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
512 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 141701.15
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
When dividing 2000 by 512, we get 3 with a remainder of 464.
Record the quotient 3 as the next digit in the result. 
Result so far: 141701.1503
If we take 1536 away from 2000, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 13:
512 can be fit into 4640 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 141701.15039
Subtracting 4608 from 4640 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 512, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 141701.15039
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
3200 divided by 512 is 6 with a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 141701.1503906
The remainder is 128 after subtracting 3072 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
When dividing 1280 by 512, we get 2 with a remainder of 256.
The next digit of our result is 2. 
Result so far: 141701.15039062
Subtract 1024 from 1280 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 141701.15039062, and the remainder is 2.56e-07.
