We look at the division of 72585640 by 815 
We're looking to find how many times 815 goes into 72585640.

On to step 1:
When dividing 7 by 815, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 815

Moving on to step 2:
If we divide 72 by 815, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 815

Step 3:
When dividing 725 by 815, we get 0 with a remainder of 725.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 725 to get 725.
Grab the next digit (8) from the dividend, add it to 725, then carry on: 7258 / 815

Going ahead to step 4:
When dividing 7258 by 815, we get 8 with a remainder of 738.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6520 from 7258, we get 738.
Grab the next digit (5) from the dividend, add it to 738, then carry on: 7385 / 815

Going ahead to step 5:
7385 divided by 815 is 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtract 7335 from 7385 to get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 815

On to step 6:
If we divide 506 by 815, we get 0 and a remainder of 506.
Put 0 as the next digit of the answer. 
Result so far: 890.0
If we subtract 0 from 506, we get 506.
Fetch the next digit (4) from the dividend, attach it to 506 and continue: 5064 / 815

Step 7:
The number 815 fits into 5064 6 times, leaving a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 8906.0
Subtract 4890 from 5064 to get 174.
Include the next digit (0) from the dividend after 174, then repeat: 1740 / 815

Advancing to step 8:
When dividing 1740 by 815, we get 2 with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 89062.0
Subtract 1630 from 1740 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
The number 815 fits into 1100 1 times, leaving a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 89062.1
Subtract 815 from 1100 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 10:
If we divide 2850 by 815, we get 3 and a remainder of 405.
The next digit of our result is 3. 
Result so far: 89062.13
Subtract 2445 from 2850 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 11:
When dividing 4050 by 815, we get 4 with a remainder of 790.
The next digit of our result is 4. 
Result so far: 89062.134
If we subtract 3260 from 4050, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 12:
When dividing 7900 by 815, we get 9 with a remainder of 565.
Record the quotient 9 as the next digit in the result. 
Result so far: 89062.1349
If we subtract 7335 from 7900, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 13:
815 can be fit into 5650 6 times, resulting in a remainder of 760.
Use 6 as the next digit of our solution. 
Result so far: 89062.13496
Subtract 4890 from 5650 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 14:
815 goes into 7600 9 times with a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 89062.134969
Subtract 7335 from 7600 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 15:
815 can be fit into 2650 3 times, resulting in a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 89062.1349693
The remainder is 205 after subtracting 2445 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 16:
815 goes into 2050 2 times with a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 89062.13496932
If we take 1630 away from 2050, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 89062.13496932, and the remainder is 4.2e-07.
