We're dividing 42056580 by 512 
Let's see how many times 512 fits into 42056580.

Moving on to step 1:
512 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 512

Advancing to step 2:
512 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 512

Step 3:
420 divided by 512 is 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Bring next digit (5) of the dividend behind the 420 and repeat the process: 4205 / 512

Advancing to step 4:
When dividing 4205 by 512, we get 8 with a remainder of 109.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 4096 from 4205, we get 109.
Include the next digit (6) from the dividend after 109, then repeat: 1096 / 512

Going ahead to step 5:
When dividing 1096 by 512, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 1024 away from 1096, we end up with 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 512

On to step 6:
512 goes into 725 1 times with a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 821.0
Deduct 512 from 725 and we're left with 213.
Bring next digit (8) of the dividend behind the 213 and repeat the process: 2138 / 512

Moving on to step 7:
512 can be fit into 2138 4 times, resulting in a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 8214.0
The remainder is 90 after subtracting 2048 from 2138.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 512

Advancing to step 8:
When dividing 900 by 512, we get 1 with a remainder of 388.
Record the quotient 1 as the next digit in the result. 
Result so far: 82141.0
If we take 512 away from 900, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 9:
If we divide 3880 by 512, we get 7 and a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 82141.7
Deduct 3584 from 3880 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 10:
512 goes into 2960 5 times with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 82141.75
Subtract 2560 from 2960 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
4000 divided by 512 is 7 with a remainder of 416.
Use 7 as the next digit of our solution. 
Result so far: 82141.757
Subtracting 3584 from 4000 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 12:
4160 divided by 512 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 82141.7578
If we take 4096 away from 4160, we end up 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.

Advancing to step 13:
512 goes into 640 1 times with a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 82141.75781
The remainder is 128 after subtracting 512 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
When dividing 1280 by 512, we get 2 with a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 82141.757812
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 15:
The number 512 fits into 2560 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 82141.7578125
Subtracting 2560 from 2560 leaves us 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.

On to step 16:
If we divide 0 by 512, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 82141.7578125
Deduct 0 from 0 and we're left 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.

Our division results in 82141.7578125 with a remaining 0.0.
