20505307 ÷ 147 
Our goal is to divide 20505307 by 147.

On to step 1:
The number 147 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 147

Moving on to step 2:
If we divide 20 by 147, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 147

Step 3:
If we divide 205 by 147, we get 1 and a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 147 from 205, we get 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 147

Moving on to step 4:
147 can be fit into 580 3 times, resulting in a remainder of 139.
The next digit of our result is 3. 
Result so far: 13.0
If we take 441 away from 580, we end up with 139.
Fetch the next digit (5) from the dividend, attach it to 139 and continue: 1395 / 147

On to step 5:
When dividing 1395 by 147, we get 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we take 1323 away from 1395, we end up with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 147

Moving on to step 6:
147 can be fit into 723 4 times, resulting in a remainder of 135.
Record the quotient 4 as the next digit in the result. 
Result so far: 1394.0
The remainder is 135 after subtracting 588 from 723.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 147

Advancing to step 7:
The number 147 fits into 1350 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 13949.0
The remainder is 27 after subtracting 1323 from 1350.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 147

Step 8:
If we divide 277 by 147, we get 1 and a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 139491.0
If we take 147 away from 277, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
The number 147 fits into 1300 8 times, leaving a remainder of 124.
Use 8 as the next digit of our solution. 
Result so far: 139491.8
Subtract 1176 from 1300 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 10:
The number 147 fits into 1240 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 139491.88
Subtracting 1176 from 1240 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 139491.88, and the remainder is 0.064.
