257047 ÷ 79 
We want to divide 257047 by 79.

Going ahead to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 79

Moving on to step 2:
The number 79 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 79

On to step 3:
When dividing 257 by 79, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 20 after subtracting 237 from 257.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 79

On to step 4:
If we divide 200 by 79, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 158 from 200 and we're left with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 79

On to step 5:
The number 79 fits into 424 5 times, leaving a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 325.0
Subtract 395 from 424 to get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 79

Going ahead to step 6:
79 can be fit into 297 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3253.0
If we subtract 237 from 297, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 79 fits into 600 7 times, leaving a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 3253.7
The remainder is 47 after subtracting 553 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
If we divide 470 by 79, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3253.75
If we take 395 away from 470, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
The number 79 fits into 750 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 3253.759
Subtract 711 from 750 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
79 can be fit into 390 4 times, resulting in a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 3253.7594
If we take 316 away from 390, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
740 divided by 79 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 3253.75949
Subtract 711 from 740 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
79 goes into 290 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 3253.759493
Subtracting 237 from 290 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
530 divided by 79 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 3253.7594936
If we subtract 474 from 530, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
79 can be fit into 560 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 3253.75949367
Subtracting 553 from 560 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 3253.75949367, with a leftover of 7e-09.
