Let's proceed to step 5:
The number 512 fits into 4700 9 times, leaving a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 4608 from 4700 to get 92.
Include the next digit (9) from the dividend after 92, then repeat: 929 / 512

Advancing to step 6:
The number 512 fits into 929 1 times, leaving a remainder of 417.
The next digit of our result is 1. 
Result so far: 491.0
If we take 512 away from 929, we end up with 417.
Take the next digit (4) from the dividend and append it to 417, then repeat: 4174 / 512

Let's proceed to step 7:
When dividing 4174 by 512, we get 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 4918.0
If we take 4096 away from 4174, we end up with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 512

Moving on to step 8:
When dividing 783 by 512, we get 1 with a remainder of 271.
Write down 1 as next digit of the result. 
Result so far: 49181.0
Deduct 512 from 783 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
If we divide 2710 by 512, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 49181.5
The remainder is 150 after subtracting 2560 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
When dividing 1500 by 512, we get 2 with a remainder of 476.
Put 2 as the next digit of the answer. 
Result so far: 49181.52
Subtracting 1024 from 1500 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 11:
512 goes into 4760 9 times with a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 49181.529
Deduct 4608 from 4760 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
When dividing 1520 by 512, we get 2 with a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 49181.5292
Subtracting 1024 from 1520 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
The number 512 fits into 4960 9 times, leaving a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 49181.52929
The remainder is 352 after subtracting 4608 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 14:
512 can be fit into 3520 6 times, resulting in a remainder of 448.
Write down 6 as next digit of the result. 
Result so far: 49181.529296
If we take 3072 away from 3520, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 15:
The number 512 fits into 4480 8 times, leaving a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 49181.5292968
Deduct 4096 from 4480 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
3840 divided by 512 is 7 with a remainder of 256.
Put 7 as the next digit of the answer. 
Result so far: 49181.52929687
Subtracting 3584 from 3840 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 49181.52929687 with a remaining 2.56e-07.
