We divide 81590434 by 513
We want to divide 81590434 by 513.

Advancing to step 1:
8 divided by 513 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 513

Going ahead to step 2:
When dividing 81 by 513, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 513

Moving on to step 3:
The number 513 fits into 815 1 times, leaving a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 513 from 815 leaves us with 302.
Bring next digit (9) of the dividend behind the 302 and repeat the process: 3029 / 513

Step 4:
3029 divided by 513 is 5 with a remainder of 464.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2565 from 3029 and we're left with 464.
Take the next digit (0) from the dividend and append it to 464, then repeat: 4640 / 513

On to step 5:
513 goes into 4640 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we take 4617 away from 4640, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 513

Step 6:
The number 513 fits into 234 0 times, leaving a remainder of 234.
Write down 0 as next digit of the result. 
Result so far: 1590.0
Subtracting 0 from 234 leaves us with 234.
Include the next digit (3) from the dividend after 234, then repeat: 2343 / 513

Advancing to step 7:
If we divide 2343 by 513, we get 4 and a remainder of 291.
The next digit of our result is 4. 
Result so far: 15904.0
The remainder is 291 after subtracting 2052 from 2343.
Include the next digit (4) from the dividend after 291, then repeat: 2914 / 513

Step 8:
The number 513 fits into 2914 5 times, leaving a remainder of 349.
The next digit of our result is 5. 
Result so far: 159045.0
Subtract 2565 from 2914 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
The number 513 fits into 3490 6 times, leaving a remainder of 412.
Use 6 as the next digit of our solution. 
Result so far: 159045.6
If we subtract 3078 from 3490, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 10:
513 can be fit into 4120 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 159045.68
The remainder is 16 after subtracting 4104 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 513, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 159045.68
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
If we divide 1600 by 513, we get 3 and a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 159045.6803
Deduct 1539 from 1600 and we're left 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.

Going ahead to step 13:
The number 513 fits into 610 1 times, leaving a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 159045.68031
The remainder is 97 after subtracting 513 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 14:
When dividing 970 by 513, we get 1 with a remainder of 457.
The number 1 becomes the next digit in our result. 
Result so far: 159045.680311
The remainder is 457 after subtracting 513 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

The quotient of the division is 159045.680311, and the remainder is 4.57e-05.
