We divide 77435942 by 512
Let's see how many times 512 fits into 77435942.

On to step 1:
If we divide 7 by 512, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 512

On to step 2:
77 divided by 512 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 512

Step 3:
If we divide 774 by 512, we get 1 and a remainder of 262.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 262 after subtracting 512 from 774.
Fetch the next digit (3) from the dividend, attach it to 262 and continue: 2623 / 512

Moving on to step 4:
When dividing 2623 by 512, we get 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2560 from 2623 and we're left with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 512

Advancing to step 5:
512 can be fit into 635 1 times, resulting in a remainder of 123.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 512 from 635 and we're left with 123.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 512

Going ahead to step 6:
When dividing 1239 by 512, we get 2 with a remainder of 215.
The next digit of our result is 2. 
Result so far: 1512.0
The remainder is 215 after subtracting 1024 from 1239.
Bring next digit (4) of the dividend behind the 215 and repeat the process: 2154 / 512

Going ahead to step 7:
512 goes into 2154 4 times with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 15124.0
Deduct 2048 from 2154 and we're left with 106.
Take the next digit (2) from the dividend and append it to 106, then repeat: 1062 / 512

On to step 8:
If we divide 1062 by 512, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 151242.0
Subtract 1024 from 1062 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
380 divided by 512 is 0 with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 151242.0
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
If we divide 3800 by 512, we get 7 and a remainder of 216.
Put 7 as the next digit of the answer. 
Result so far: 151242.07
Subtracting 3584 from 3800 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
512 can be fit into 2160 4 times, resulting in a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 151242.074
Subtract 2048 from 2160 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
When dividing 1120 by 512, we get 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 151242.0742
Subtract 1024 from 1120 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
When dividing 960 by 512, we get 1 with a remainder of 448.
Write down 1 as next digit of the result. 
Result so far: 151242.07421
Subtract 512 from 960 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 14:
4480 divided by 512 is 8 with a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 151242.074218
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.

Advancing to step 15:
512 can be fit into 3840 7 times, resulting in a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 151242.0742187
Deduct 3584 from 3840 and we're left 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.

Let's proceed to step 16:
When dividing 2560 by 512, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 151242.07421875
Deduct 2560 from 2560 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.

The quotient of the division is 151242.07421875, and the remainder is 0.0.
