80593278 ÷ 159 
We're looking to find how many times 159 goes into 80593278.

On to step 1:
If we divide 8 by 159, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 159

On to step 2:
If we divide 80 by 159, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 159

Step 3:
159 can be fit into 805 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 10 after subtracting 795 from 805.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 159

Let's proceed to step 4:
When dividing 109 by 159, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 109 and we're left with 109.
Take the next digit (3) from the dividend and append it to 109, then repeat: 1093 / 159

Moving on to step 5:
When dividing 1093 by 159, we get 6 with a remainder of 139.
Record the quotient 6 as the next digit in the result. 
Result so far: 506.0
Deduct 954 from 1093 and we're left with 139.
Bring next digit (2) of the dividend behind the 139 and repeat the process: 1392 / 159

Advancing to step 6:
The number 159 fits into 1392 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 5068.0
If we take 1272 away from 1392, we end up with 120.
Append the next digit (7) from the dividend to 120 and continue with: 1207 / 159

Let's proceed to step 7:
159 goes into 1207 7 times with a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 50687.0
Subtract 1113 from 1207 to get 94.
Fetch the next digit (8) from the dividend, attach it to 94 and continue: 948 / 159

On to step 8:
The number 159 fits into 948 5 times, leaving a remainder of 153.
The number 5 becomes the next digit in our result. 
Result so far: 506875.0
If we take 795 away from 948, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
If we divide 1530 by 159, we get 9 and a remainder of 99.
The next digit of our result is 9. 
Result so far: 506875.9
If we subtract 1431 from 1530, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 10:
159 can be fit into 990 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 506875.96
If we subtract 954 from 990, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
360 divided by 159 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 506875.962
If we take 318 away from 360, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
420 divided by 159 is 2 with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 506875.9622
If we take 318 away from 420, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 506875.9622 and a remainder of 0.00102.
