20896637 ÷ 159 
Our goal is to divide 20896637 by 159.

On to step 1:
When dividing 2 by 159, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 159

Step 2:
159 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 159

Let's proceed to step 3:
If we divide 208 by 159, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 159 from 208, we get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 159

Moving on to step 4:
159 can be fit into 499 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 22 after subtracting 477 from 499.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 159

Step 5:
The number 159 fits into 226 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we take 159 away from 226, we end up with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 159

On to step 6:
When dividing 676 by 159, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 1314.0
If we subtract 636 from 676, we get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 159

Step 7:
When dividing 403 by 159, we get 2 with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 13142.0
Subtract 318 from 403 to get 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 159

Going ahead to step 8:
The number 159 fits into 857 5 times, leaving a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 131425.0
Subtract 795 from 857 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
159 goes into 620 3 times with a remainder of 143.
The next digit of our result is 3. 
Result so far: 131425.3
Subtracting 477 from 620 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 10:
If we divide 1430 by 159, we get 8 and a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 131425.38
Subtracting 1272 from 1430 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 11:
1580 divided by 159 is 9 with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 131425.389
If we subtract 1431 from 1580, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 12:
159 goes into 1490 9 times with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 131425.3899
If we subtract 1431 from 1490, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 131425.3899 and a remainder of 0.00059.
