We divide 86156354 by 512
We're looking to find how many times 512 goes into 86156354.

Going ahead to step 1:
512 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 512

On to step 2:
If we divide 86 by 512, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 512

Step 3:
512 can be fit into 861 1 times, resulting in a remainder of 349.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 512 away from 861, we end up with 349.
Grab the next digit (5) from the dividend, add it to 349, then carry on: 3495 / 512

On to step 4:
If we divide 3495 by 512, we get 6 and a remainder of 423.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3072 from 3495 leaves us with 423.
Include the next digit (6) from the dividend after 423, then repeat: 4236 / 512

Advancing to step 5:
512 can be fit into 4236 8 times, resulting in a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtract 4096 from 4236 to get 140.
Bring next digit (3) of the dividend behind the 140 and repeat the process: 1403 / 512

Advancing to step 6:
If we divide 1403 by 512, we get 2 and a remainder of 379.
The number 2 becomes the next digit in our result. 
Result so far: 1682.0
Deduct 1024 from 1403 and we're left with 379.
Bring next digit (5) of the dividend behind the 379 and repeat the process: 3795 / 512

Moving on to step 7:
512 can be fit into 3795 7 times, resulting in a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 16827.0
The remainder is 211 after subtracting 3584 from 3795.
Fetch the next digit (4) from the dividend, attach it to 211 and continue: 2114 / 512

Step 8:
2114 divided by 512 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 168274.0
Subtracting 2048 from 2114 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
512 can be fit into 660 1 times, resulting in a remainder of 148.
The next digit of our result is 1. 
Result so far: 168274.1
Deduct 512 from 660 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
If we divide 1480 by 512, we get 2 and a remainder of 456.
The number 2 becomes the next digit in our result. 
Result so far: 168274.12
Subtract 1024 from 1480 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 11:
512 goes into 4560 8 times with a remainder of 464.
Write down 8 as next digit of the result. 
Result so far: 168274.128
Subtract 4096 from 4560 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
4640 divided by 512 is 9 with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 168274.1289
Deduct 4608 from 4640 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
The number 512 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 168274.1289
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
If we divide 3200 by 512, we get 6 and a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 168274.128906
The remainder is 128 after subtracting 3072 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
512 can be fit into 1280 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 168274.1289062
Subtract 1024 from 1280 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
512 goes into 2560 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 168274.12890625
If we take 2560 away from 2560, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 168274.12890625 with a remainder of 0.0.
