Let's divide 257617 by 79
Our goal is to divide 257617 by 79.

Step 1:
If we divide 2 by 79, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 79

Advancing to step 2:
79 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 79

Advancing to step 3:
79 goes into 257 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 237 from 257 and we're left with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 79

Let's proceed to step 4:
When dividing 206 by 79, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 158 from 206 and we're left with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 79

Step 5:
If we divide 481 by 79, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
If we take 474 away from 481, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 79

Step 6:
77 divided by 79 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 3260.0
The remainder is 77 after subtracting 0 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
The number 79 fits into 770 9 times, leaving a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 3260.9
Subtract 711 from 770 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
590 divided by 79 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3260.97
Deduct 553 from 590 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
370 divided by 79 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 3260.974
If we subtract 316 from 370, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
79 can be fit into 540 6 times, resulting in a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 3260.9746
If we take 474 away from 540, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
660 divided by 79 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 3260.97468
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
The number 79 fits into 280 3 times, leaving a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3260.974683
Subtracting 237 from 280 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
79 can be fit into 430 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 3260.9746835
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
If we divide 350 by 79, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 3260.97468354
If we take 316 away from 350, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 3260.97468354 with a remainder of 3.4e-08.
