77508836 ÷ 511 
We want to divide 77508836 by 511.

On to step 1:
511 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 511

Moving on to step 2:
77 divided by 511 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 511

Going ahead to step 3:
775 divided by 511 is 1 with a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 511 from 775 and we're left with 264.
Include the next digit (0) from the dividend after 264, then repeat: 2640 / 511

Moving on to step 4:
2640 divided by 511 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2555 from 2640 to get 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 511

On to step 5:
If we divide 858 by 511, we get 1 and a remainder of 347.
The next digit of our result is 1. 
Result so far: 151.0
Subtracting 511 from 858 leaves us with 347.
Grab the next digit (8) from the dividend, add it to 347, then carry on: 3478 / 511

Let's proceed to step 6:
When dividing 3478 by 511, we get 6 with a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 1516.0
Subtract 3066 from 3478 to get 412.
Take the next digit (3) from the dividend and append it to 412, then repeat: 4123 / 511

Step 7:
The number 511 fits into 4123 8 times, leaving a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 15168.0
Deduct 4088 from 4123 and we're left with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 511

Advancing to step 8:
When dividing 356 by 511, we get 0 with a remainder of 356.
Write down 0 as next digit of the result. 
Result so far: 151680.0
The remainder is 356 after subtracting 0 from 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 9:
3560 divided by 511 is 6 with a remainder of 494.
The number 6 becomes the next digit in our result. 
Result so far: 151680.6
If we subtract 3066 from 3560, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 10:
4940 divided by 511 is 9 with a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 151680.69
If we subtract 4599 from 4940, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 11:
511 can be fit into 3410 6 times, resulting in a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 151680.696
If we take 3066 away from 3410, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 12:
When dividing 3440 by 511, we get 6 with a remainder of 374.
Use 6 as the next digit of our solution. 
Result so far: 151680.6966
Deduct 3066 from 3440 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 151680.6966, with a leftover of 0.00374.
