14993488 ÷ 686 
We want to figure out the number of times 14993488 can be divided by 686.

Step 1:
If we divide 1 by 686, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 686

Going ahead to step 2:
686 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 686

Let's proceed to step 3:
When dividing 149 by 686, we get 0 with a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 149, we get 149.
Include the next digit (9) from the dividend after 149, then repeat: 1499 / 686

On to step 4:
686 goes into 1499 2 times with a remainder of 127.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1372 from 1499 and we're left with 127.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 686

Advancing to step 5:
686 can be fit into 1273 1 times, resulting in a remainder of 587.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 587 after subtracting 686 from 1273.
Grab the next digit (4) from the dividend, add it to 587, then carry on: 5874 / 686

Step 6:
686 can be fit into 5874 8 times, resulting in a remainder of 386.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Deduct 5488 from 5874 and we're left with 386.
Grab the next digit (8) from the dividend, add it to 386, then carry on: 3868 / 686

Step 7:
The number 686 fits into 3868 5 times, leaving a remainder of 438.
Record the quotient 5 as the next digit in the result. 
Result so far: 2185.0
Subtracting 3430 from 3868 leaves us with 438.
Include the next digit (8) from the dividend after 438, then repeat: 4388 / 686

Step 8:
When dividing 4388 by 686, we get 6 with a remainder of 272.
The next digit of our result is 6. 
Result so far: 21856.0
Deduct 4116 from 4388 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
The number 686 fits into 2720 3 times, leaving a remainder of 662.
Put 3 as the next digit of the answer. 
Result so far: 21856.3
If we subtract 2058 from 2720, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 10:
686 goes into 6620 9 times with a remainder of 446.
The next digit of our result is 9. 
Result so far: 21856.39
If we subtract 6174 from 6620, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 11:
4460 divided by 686 is 6 with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 21856.396
Subtract 4116 from 4460 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
3440 divided by 686 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 21856.3965
The remainder is 10 after subtracting 3430 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
686 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 21856.3965
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
686 goes into 1000 1 times with a remainder of 314.
The next digit of our result is 1. 
Result so far: 21856.396501
The remainder is 314 after subtracting 686 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 15:
686 can be fit into 3140 4 times, resulting in a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 21856.3965014
If we take 2744 away from 3140, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 16:
3960 divided by 686 is 5 with a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 21856.39650145
Deduct 3430 from 3960 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

In conclusion, the division gives 21856.39650145 with a balance of 5.3e-07.
