We divide 257315 by 77
Our goal is to divide 257315 by 77.

Moving on to step 1:
2 divided by 77 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 77

Step 2:
25 divided by 77 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 77

Going ahead to step 3:
257 divided by 77 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 231 from 257 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 77

Advancing to step 4:
If we divide 263 by 77, we get 3 and a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 231 from 263, we get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 77

On to step 5:
When dividing 321 by 77, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 334.0
If we subtract 308 from 321, we get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 77

Step 6:
77 can be fit into 135 1 times, resulting in a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 3341.0
The remainder is 58 after subtracting 77 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
77 goes into 580 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 3341.7
If we subtract 539 from 580, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
410 divided by 77 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3341.75
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
When dividing 250 by 77, we get 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3341.753
The remainder is 19 after subtracting 231 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
77 goes into 190 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 3341.7532
Subtract 154 from 190 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 77, we get 4 and a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 3341.75324
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
The number 77 fits into 520 6 times, leaving a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 3341.753246
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
77 can be fit into 580 7 times, resulting in a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 3341.7532467
Subtracting 539 from 580 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 14:
The number 77 fits into 410 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3341.75324675
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 3341.75324675 with a remainder of 2.5e-08.
