We look at the division of 80890768 by 513 
Our goal is to divide 80890768 by 513.

Going ahead to step 1:
The number 513 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 513

Advancing to step 2:
513 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 513

Advancing to step 3:
513 can be fit into 808 1 times, resulting in a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 513 away from 808, we end up with 295.
Include the next digit (9) from the dividend after 295, then repeat: 2959 / 513

Moving on to step 4:
The number 513 fits into 2959 5 times, leaving a remainder of 394.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2565 from 2959 and we're left with 394.
Take the next digit (0) from the dividend and append it to 394, then repeat: 3940 / 513

Let's proceed to step 5:
513 can be fit into 3940 7 times, resulting in a remainder of 349.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
The remainder is 349 after subtracting 3591 from 3940.
Take the next digit (7) from the dividend and append it to 349, then repeat: 3497 / 513

On to step 6:
513 can be fit into 3497 6 times, resulting in a remainder of 419.
Write down 6 as next digit of the result. 
Result so far: 1576.0
Deduct 3078 from 3497 and we're left with 419.
Bring next digit (6) of the dividend behind the 419 and repeat the process: 4196 / 513

Advancing to step 7:
The number 513 fits into 4196 8 times, leaving a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 15768.0
The remainder is 92 after subtracting 4104 from 4196.
Fetch the next digit (8) from the dividend, attach it to 92 and continue: 928 / 513

Going ahead to step 8:
513 can be fit into 928 1 times, resulting in a remainder of 415.
The number 1 becomes the next digit in our result. 
Result so far: 157681.0
The remainder is 415 after subtracting 513 from 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 9:
When dividing 4150 by 513, we get 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 157681.8
The remainder is 46 after subtracting 4104 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
460 divided by 513 is 0 with a remainder of 460.
The next digit of our result is 0. 
Result so far: 157681.8
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
4600 divided by 513 is 8 with a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 157681.808
Deduct 4104 from 4600 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 12:
513 goes into 4960 9 times with a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 157681.8089
Deduct 4617 from 4960 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 13:
513 can be fit into 3430 6 times, resulting in a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 157681.80896
If we subtract 3078 from 3430, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
3520 divided by 513 is 6 with a remainder of 442.
The number 6 becomes the next digit in our result. 
Result so far: 157681.808966
Subtract 3078 from 3520 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

The final outcome is 157681.808966, with a leftover of 4.42e-05.
