305887 ÷ 79 
We're looking to find how many times 79 goes into 305887.

Step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 79

Let's proceed to step 2:
If we divide 30 by 79, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 79

Moving on to step 3:
305 divided by 79 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 237 from 305, we get 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 79

Going ahead to step 4:
688 divided by 79 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 632 from 688 and we're left with 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 79

On to step 5:
The number 79 fits into 568 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 387.0
The remainder is 15 after subtracting 553 from 568.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 79

Going ahead to step 6:
If we divide 157 by 79, we get 1 and a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 3871.0
The remainder is 78 after subtracting 79 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
79 goes into 780 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 3871.9
Subtract 711 from 780 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
If we divide 690 by 79, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 3871.98
If we take 632 away from 690, we end up 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.

On to step 9:
79 can be fit into 580 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 3871.987
Subtracting 553 from 580 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
The number 79 fits into 270 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 3871.9873
If we subtract 237 from 270, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
When dividing 330 by 79, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 3871.98734
Deduct 316 from 330 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
140 divided by 79 is 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 3871.987341
If we take 79 away from 140, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
If we divide 610 by 79, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 3871.9873417
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
570 divided by 79 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3871.98734177
If we take 553 away from 570, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 3871.98734177 and a remainder of 1.7e-08.
