77593609 ÷ 289 
Let's see how many times 289 fits into 77593609.

Step 1:
289 can be fit into 7 0 times, resulting in 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.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 289

On to step 2:
When dividing 77 by 289, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 289

On to step 3:
When dividing 775 by 289, we get 2 with a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 197 after subtracting 578 from 775.
Append the next digit (9) from the dividend to 197 and continue with: 1979 / 289

On to step 4:
When dividing 1979 by 289, we get 6 with a remainder of 245.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 1734 from 1979 to get 245.
Include the next digit (3) from the dividend after 245, then repeat: 2453 / 289

Going ahead to step 5:
The number 289 fits into 2453 8 times, leaving a remainder of 141.
Write down 8 as next digit of the result. 
Result so far: 268.0
Subtracting 2312 from 2453 leaves us with 141.
Grab the next digit (6) from the dividend, add it to 141, then carry on: 1416 / 289

On to step 6:
1416 divided by 289 is 4 with a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 2684.0
If we subtract 1156 from 1416, we get 260.
Take the next digit (0) from the dividend and append it to 260, then repeat: 2600 / 289

Advancing to step 7:
289 goes into 2600 8 times with a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 26848.0
Subtracting 2312 from 2600 leaves us with 288.
Bring next digit (9) of the dividend behind the 288 and repeat the process: 2889 / 289

Advancing to step 8:
289 can be fit into 2889 9 times, resulting in a remainder of 288.
The next digit of our result is 9. 
Result so far: 268489.0
If we subtract 2601 from 2889, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 9:
2880 divided by 289 is 9 with a remainder of 279.
Put 9 as the next digit of the answer. 
Result so far: 268489.9
Subtract 2601 from 2880 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 10:
289 goes into 2790 9 times with a remainder of 189.
The next digit of our result is 9. 
Result so far: 268489.99
Subtracting 2601 from 2790 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The final result is 268489.99 with a remainder of 0.189.
