15549168 divided by 686 
We want to figure out the number of times 15549168 can be divided by 686.

On to step 1:
686 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 686

Step 2:
When dividing 15 by 686, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 686

Going ahead to step 3:
When dividing 155 by 686, we get 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Include the next digit (4) from the dividend after 155, then repeat: 1554 / 686

Step 4:
686 goes into 1554 2 times with a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1372 from 1554 to get 182.
Grab the next digit (9) from the dividend, add it to 182, then carry on: 1829 / 686

On to step 5:
If we divide 1829 by 686, we get 2 and a remainder of 457.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 1372 from 1829, we get 457.
Grab the next digit (1) from the dividend, add it to 457, then carry on: 4571 / 686

On to step 6:
When dividing 4571 by 686, we get 6 with a remainder of 455.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
Deduct 4116 from 4571 and we're left with 455.
Include the next digit (6) from the dividend after 455, then repeat: 4556 / 686

On to step 7:
686 can be fit into 4556 6 times, resulting in a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 2266.0
If we subtract 4116 from 4556, we get 440.
Grab the next digit (8) from the dividend, add it to 440, then carry on: 4408 / 686

On to step 8:
4408 divided by 686 is 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 22666.0
The remainder is 292 after subtracting 4116 from 4408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 9:
If we divide 2920 by 686, we get 4 and a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 22666.4
If we subtract 2744 from 2920, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
686 goes into 1760 2 times with a remainder of 388.
The next digit of our result is 2. 
Result so far: 22666.42
If we take 1372 away from 1760, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 11:
3880 divided by 686 is 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 22666.425
If we take 3430 away from 3880, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 12:
686 goes into 4500 6 times with a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 22666.4256
Deduct 4116 from 4500 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 13:
If we divide 3840 by 686, we get 5 and a remainder of 410.
The next digit of our result is 5. 
Result so far: 22666.42565
Subtracting 3430 from 3840 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 14:
When dividing 4100 by 686, we get 5 with a remainder of 670.
Use 5 as the next digit of our solution. 
Result so far: 22666.425655
Deduct 3430 from 4100 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

The final result is 22666.425655 with a remainder of 6.7e-05.
