We look at the division of 20465255 by 151 
Our goal is to divide 20465255 by 151.

Let's proceed to step 1:
The number 151 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 151

Going ahead to step 2:
The number 151 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 151

On to step 3:
151 can be fit into 204 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 151 from 204, we get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 151

On to step 4:
151 can be fit into 536 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 453 from 536 and we're left with 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 151

Advancing to step 5:
The number 151 fits into 835 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we take 755 away from 835, we end up with 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 151

Let's proceed to step 6:
151 goes into 802 5 times with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 1355.0
If we take 755 away from 802, we end up with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 151

Step 7:
475 divided by 151 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13553.0
The remainder is 22 after subtracting 453 from 475.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 151

On to step 8:
The number 151 fits into 225 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 135531.0
Subtracting 151 from 225 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
If we divide 740 by 151, we get 4 and a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 135531.4
Subtracting 604 from 740 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
The number 151 fits into 1360 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 135531.49
If we subtract 1359 from 1360, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
151 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 135531.49
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 151 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 135531.49
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 135531.49, with a leftover of 0.001.
