We're dividing 13890576 by 317 
We want to figure out the number of times 13890576 can be divided by 317.

Advancing to step 1:
When dividing 1 by 317, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 317

Step 2:
The number 317 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 317

Going ahead to step 3:
If we divide 138 by 317, we get 0 and a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 138 to get 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 317

Moving on to step 4:
317 can be fit into 1389 4 times, resulting in a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 1268 from 1389, we get 121.
Include the next digit (0) from the dividend after 121, then repeat: 1210 / 317

Moving on to step 5:
When dividing 1210 by 317, we get 3 with a remainder of 259.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 951 from 1210, we get 259.
Take the next digit (5) from the dividend and append it to 259, then repeat: 2595 / 317

On to step 6:
317 can be fit into 2595 8 times, resulting in a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 438.0
If we take 2536 away from 2595, we end up with 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 317

Step 7:
If we divide 597 by 317, we get 1 and a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 4381.0
If we take 317 away from 597, we end up with 280.
Bring next digit (6) of the dividend behind the 280 and repeat the process: 2806 / 317

On to step 8:
If we divide 2806 by 317, we get 8 and a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 43818.0
Subtracting 2536 from 2806 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
317 goes into 2700 8 times with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 43818.8
Deduct 2536 from 2700 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 10:
317 goes into 1640 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 43818.85
If we take 1585 away from 1640, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
When dividing 550 by 317, we get 1 with a remainder of 233.
Put 1 as the next digit of the answer. 
Result so far: 43818.851
The remainder is 233 after subtracting 317 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 12:
317 can be fit into 2330 7 times, resulting in a remainder of 111.
The next digit of our result is 7. 
Result so far: 43818.8517
If we subtract 2219 from 2330, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 13:
317 goes into 1110 3 times with a remainder of 159.
Record the quotient 3 as the next digit in the result. 
Result so far: 43818.85173
Subtract 951 from 1110 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 14:
If we divide 1590 by 317, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 43818.851735
If we subtract 1585 from 1590, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 15:
317 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 43818.851735
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
317 can be fit into 500 1 times, resulting in a remainder of 183.
The next digit of our result is 1. 
Result so far: 43818.85173501
If we take 317 away from 500, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

After the division, we end up with 43818.85173501 and a remainder of 1.83e-07.
