99677313 divided by 257 
We're looking to find how many times 257 goes into 99677313.

Step 1:
257 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 257

On to step 2:
When dividing 99 by 257, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 257

Moving on to step 3:
996 divided by 257 is 3 with a remainder of 225.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 771 away from 996, we end up with 225.
Bring next digit (7) of the dividend behind the 225 and repeat the process: 2257 / 257

Let's proceed to step 4:
The number 257 fits into 2257 8 times, leaving a remainder of 201.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 2056 from 2257 leaves us with 201.
Bring next digit (7) of the dividend behind the 201 and repeat the process: 2017 / 257

Going ahead to step 5:
2017 divided by 257 is 7 with a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 387.0
If we subtract 1799 from 2017, we get 218.
Include the next digit (3) from the dividend after 218, then repeat: 2183 / 257

Let's proceed to step 6:
2183 divided by 257 is 8 with a remainder of 127.
The next digit of our result is 8. 
Result so far: 3878.0
Subtracting 2056 from 2183 leaves us with 127.
Grab the next digit (1) from the dividend, add it to 127, then carry on: 1271 / 257

Let's proceed to step 7:
257 can be fit into 1271 4 times, resulting in a remainder of 243.
Write down 4 as next digit of the result. 
Result so far: 38784.0
Subtract 1028 from 1271 to get 243.
Bring next digit (3) of the dividend behind the 243 and repeat the process: 2433 / 257

Moving on to step 8:
257 can be fit into 2433 9 times, resulting in a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 387849.0
The remainder is 120 after subtracting 2313 from 2433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 9:
257 can be fit into 1200 4 times, resulting in a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 387849.4
Subtract 1028 from 1200 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
1720 divided by 257 is 6 with a remainder of 178.
The next digit of our result is 6. 
Result so far: 387849.46
If we take 1542 away from 1720, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 11:
1780 divided by 257 is 6 with a remainder of 238.
The next digit of our result is 6. 
Result so far: 387849.466
Subtracting 1542 from 1780 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 387849.466, with a leftover of 0.0238.
