81603096 ÷ 159 
Let's see how many times 159 fits into 81603096.

Advancing to step 1:
When dividing 8 by 159, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 159

Going ahead to step 2:
159 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 159

Let's proceed to step 3:
When dividing 816 by 159, we get 5 with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 795 from 816, we get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 159

Step 4:
If we divide 210 by 159, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 159 from 210 and we're left with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 159

Step 5:
When dividing 513 by 159, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
If we take 477 away from 513, we end up with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 159

Going ahead to step 6:
The number 159 fits into 360 2 times, leaving a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 5132.0
The remainder is 42 after subtracting 318 from 360.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 159

Moving on to step 7:
If we divide 429 by 159, we get 2 and a remainder of 111.
Write down 2 as next digit of the result. 
Result so far: 51322.0
Subtract 318 from 429 to get 111.
Append the next digit (6) from the dividend to 111 and continue with: 1116 / 159

On to step 8:
If we divide 1116 by 159, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 513227.0
If we take 1113 away from 1116, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
When dividing 30 by 159, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 513227.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
159 can be fit into 300 1 times, resulting in a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 513227.01
Subtracting 159 from 300 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 11:
159 goes into 1410 8 times with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 513227.018
Deduct 1272 from 1410 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 12:
The number 159 fits into 1380 8 times, leaving a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 513227.0188
If we subtract 1272 from 1380, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 513227.0188 and a remainder of 0.00108.
