77486016 divided by 435 
Our goal is to divide 77486016 by 435.

Moving on to step 1:
When dividing 7 by 435, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 435

Step 2:
When dividing 77 by 435, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 435

On to step 3:
The number 435 fits into 774 1 times, leaving a remainder of 339.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 435 from 774 leaves us with 339.
Include the next digit (8) from the dividend after 339, then repeat: 3398 / 435

Going ahead to step 4:
If we divide 3398 by 435, we get 7 and a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3045 from 3398, we get 353.
Include the next digit (6) from the dividend after 353, then repeat: 3536 / 435

On to step 5:
435 goes into 3536 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we take 3480 away from 3536, we end up with 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 435

Moving on to step 6:
If we divide 560 by 435, we get 1 and a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 1781.0
If we take 435 away from 560, we end up with 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 435

Advancing to step 7:
If we divide 1251 by 435, we get 2 and a remainder of 381.
Write down 2 as next digit of the result. 
Result so far: 17812.0
Subtracting 870 from 1251 leaves us with 381.
Append the next digit (6) from the dividend to 381 and continue with: 3816 / 435

Advancing to step 8:
435 can be fit into 3816 8 times, resulting in a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 178128.0
If we subtract 3480 from 3816, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
435 can be fit into 3360 7 times, resulting in a remainder of 315.
Record the quotient 7 as the next digit in the result. 
Result so far: 178128.7
Subtract 3045 from 3360 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 10:
435 can be fit into 3150 7 times, resulting in a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 178128.77
Subtracting 3045 from 3150 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 178128.77, with a leftover of 0.105.
