77774618 ÷ 435 
Let's see how many times 435 fits into 77774618.

On to step 1:
7 divided by 435 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 435

Advancing to step 2:
The number 435 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 435

Step 3:
435 can be fit into 777 1 times, resulting in a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 435 from 777, we get 342.
Include the next digit (7) from the dividend after 342, then repeat: 3427 / 435

Advancing to step 4:
3427 divided by 435 is 7 with a remainder of 382.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 382 after subtracting 3045 from 3427.
Fetch the next digit (4) from the dividend, attach it to 382 and continue: 3824 / 435

Let's proceed to step 5:
435 goes into 3824 8 times with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtracting 3480 from 3824 leaves us with 344.
Include the next digit (6) from the dividend after 344, then repeat: 3446 / 435

Let's proceed to step 6:
435 can be fit into 3446 7 times, resulting in a remainder of 401.
Put 7 as the next digit of the answer. 
Result so far: 1787.0
Subtracting 3045 from 3446 leaves us with 401.
Take the next digit (1) from the dividend and append it to 401, then repeat: 4011 / 435

Let's proceed to step 7:
435 can be fit into 4011 9 times, resulting in a remainder of 96.
The number 9 becomes the next digit in our result. 
Result so far: 17879.0
Subtracting 3915 from 4011 leaves us with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 435

Advancing to step 8:
968 divided by 435 is 2 with a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 178792.0
If we take 870 away from 968, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
980 divided by 435 is 2 with a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 178792.2
If we subtract 870 from 980, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
1100 divided by 435 is 2 with a remainder of 230.
Write down 2 as next digit of the result. 
Result so far: 178792.22
Subtract 870 from 1100 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 178792.22, with a leftover of 0.23.
