78997086 divided by 317 
Our goal is to divide 78997086 by 317.

Going ahead to step 1:
If we divide 7 by 317, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 317

Going ahead to step 2:
317 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 317

Let's proceed to step 3:
317 can be fit into 789 2 times, resulting in a remainder of 155.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 155 after subtracting 634 from 789.
Bring next digit (9) of the dividend behind the 155 and repeat the process: 1559 / 317

Moving on to step 4:
The number 317 fits into 1559 4 times, leaving a remainder of 291.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 291 after subtracting 1268 from 1559.
Fetch the next digit (7) from the dividend, attach it to 291 and continue: 2917 / 317

Step 5:
If we divide 2917 by 317, we get 9 and a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
The remainder is 64 after subtracting 2853 from 2917.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 317

On to step 6:
317 goes into 640 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2492.0
Subtract 634 from 640 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 317

Let's proceed to step 7:
When dividing 68 by 317, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 24920.0
If we subtract 0 from 68, we get 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 317

Let's proceed to step 8:
The number 317 fits into 686 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 249202.0
If we subtract 634 from 686, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
317 can be fit into 520 1 times, resulting in a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 249202.1
If we subtract 317 from 520, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 10:
2030 divided by 317 is 6 with a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 249202.16
Subtracting 1902 from 2030 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
317 can be fit into 1280 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 249202.164
Subtracting 1268 from 1280 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 317 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 249202.164
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
1200 divided by 317 is 3 with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 249202.16403
The remainder is 249 after subtracting 951 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 14:
The number 317 fits into 2490 7 times, leaving a remainder of 271.
Write down 7 as next digit of the result. 
Result so far: 249202.164037
Subtract 2219 from 2490 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 15:
317 goes into 2710 8 times with a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 249202.1640378
If we subtract 2536 from 2710, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 16:
317 can be fit into 1740 5 times, resulting in a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 249202.16403785
If we take 1585 away from 1740, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

After the division, we end up with 249202.16403785 and a remainder of 1.55e-07.
