511 can be fit into 1490 2 times, resulting in a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 1472.0
If we subtract 1022 from 1490, we get 468.
Include the next digit (4) from the dividend after 468, then repeat: 4684 / 511

Step 7:
The number 511 fits into 4684 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 14729.0
The remainder is 85 after subtracting 4599 from 4684.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 511

Let's proceed to step 8:
511 goes into 859 1 times with a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 147291.0
The remainder is 348 after subtracting 511 from 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 9:
If we divide 3480 by 511, we get 6 and a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 147291.6
Subtract 3066 from 3480 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 10:
If we divide 4140 by 511, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 147291.68
If we subtract 4088 from 4140, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
520 divided by 511 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 147291.681
The remainder is 9 after subtracting 511 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
90 divided by 511 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 147291.681
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
When dividing 900 by 511, we get 1 with a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 147291.68101
Subtracting 511 from 900 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 14:
When dividing 3890 by 511, we get 7 with a remainder of 313.
Write down 7 as next digit of the result. 
Result so far: 147291.681017
If we take 3577 away from 3890, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 15:
511 goes into 3130 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 147291.6810176
Subtracting 3066 from 3130 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.

On to step 16:
When dividing 640 by 511, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 147291.68101761
Subtracting 511 from 640 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 147291.68101761 with a remainder of 1.29e-07.
