We look at the division of 5231590 by 73 
We're looking to find how many times 73 goes into 5231590.

Advancing to step 1:
5 divided by 73 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 73

Step 2:
52 divided by 73 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 73

Going ahead to step 3:
When dividing 523 by 73, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 511 from 523, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 73

Going ahead to step 4:
The number 73 fits into 121 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 73 from 121 to get 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 73

Step 5:
73 can be fit into 485 6 times, resulting in a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 716.0
If we take 438 away from 485, we end up with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 73

Going ahead to step 6:
479 divided by 73 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 7166.0
Deduct 438 from 479 and we're left with 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 73

Going ahead to step 7:
73 can be fit into 410 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 71665.0
The remainder is 45 after subtracting 365 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
If we divide 450 by 73, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 71665.6
If we subtract 438 from 450, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
73 can be fit into 120 1 times, resulting in a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 71665.61
Deduct 73 from 120 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
73 goes into 470 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 71665.616
If we take 438 away from 470, we end up 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 11:
The number 73 fits into 320 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 71665.6164
Subtracting 292 from 320 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
When dividing 280 by 73, we get 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 71665.61643
Subtracting 219 from 280 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
When dividing 610 by 73, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 71665.616438
If we take 584 away from 610, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
The number 73 fits into 260 3 times, leaving a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 71665.6164383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 15:
If we divide 410 by 73, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 71665.61643835
If we subtract 365 from 410, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 71665.61643835 with a remaining 4.5e-08.
