72040456 divided by 585 
We want to figure out the number of times 72040456 can be divided by 585.

Let's proceed to step 1:
585 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 585

Going ahead to step 2:
585 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 585

Step 3:
If we divide 720 by 585, we get 1 and a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 585 from 720 and we're left with 135.
Fetch the next digit (4) from the dividend, attach it to 135 and continue: 1354 / 585

On to step 4:
When dividing 1354 by 585, we get 2 with a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1170 from 1354 leaves us with 184.
Take the next digit (0) from the dividend and append it to 184, then repeat: 1840 / 585

Advancing to step 5:
585 can be fit into 1840 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we subtract 1755 from 1840, we get 85.
Include the next digit (4) from the dividend after 85, then repeat: 854 / 585

Advancing to step 6:
The number 585 fits into 854 1 times, leaving a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 1231.0
Deduct 585 from 854 and we're left with 269.
Include the next digit (5) from the dividend after 269, then repeat: 2695 / 585

On to step 7:
585 can be fit into 2695 4 times, resulting in a remainder of 355.
The next digit of our result is 4. 
Result so far: 12314.0
If we subtract 2340 from 2695, we get 355.
Take the next digit (6) from the dividend and append it to 355, then repeat: 3556 / 585

Moving on to step 8:
The number 585 fits into 3556 6 times, leaving a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 123146.0
The remainder is 46 after subtracting 3510 from 3556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
If we divide 460 by 585, we get 0 and a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 123146.0
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
585 can be fit into 4600 7 times, resulting in a remainder of 505.
The number 7 becomes the next digit in our result. 
Result so far: 123146.07
If we subtract 4095 from 4600, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 11:
When dividing 5050 by 585, we get 8 with a remainder of 370.
Put 8 as the next digit of the answer. 
Result so far: 123146.078
If we take 4680 away from 5050, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
585 can be fit into 3700 6 times, resulting in a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 123146.0786
Subtracting 3510 from 3700 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
1900 divided by 585 is 3 with a remainder of 145.
Put 3 as the next digit of the answer. 
Result so far: 123146.07863
If we take 1755 away from 1900, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 14:
585 goes into 1450 2 times with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 123146.078632
Deduct 1170 from 1450 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
When dividing 2800 by 585, we get 4 with a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 123146.0786324
The remainder is 460 after subtracting 2340 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
585 can be fit into 4600 7 times, resulting in a remainder of 505.
Put 7 as the next digit of the answer. 
Result so far: 123146.07863247
If we take 4095 away from 4600, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The final outcome is 123146.07863247, with a leftover of 5.05e-07.
