76550575 ÷ 686 
Let's see how many times 686 fits into 76550575.

Moving on to step 1:
The number 686 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 686

Moving on to step 2:
76 divided by 686 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (5) from the dividend and append it to 76, then repeat: 765 / 686

Moving on to step 3:
The number 686 fits into 765 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 79 after subtracting 686 from 765.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 686

On to step 4:
795 divided by 686 is 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 686 from 795, we get 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 686

Going ahead to step 5:
When dividing 1090 by 686, we get 1 with a remainder of 404.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 686 from 1090 leaves us with 404.
Include the next digit (5) from the dividend after 404, then repeat: 4045 / 686

On to step 6:
If we divide 4045 by 686, we get 5 and a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
The remainder is 615 after subtracting 3430 from 4045.
Include the next digit (7) from the dividend after 615, then repeat: 6157 / 686

Step 7:
If we divide 6157 by 686, we get 8 and a remainder of 669.
Record the quotient 8 as the next digit in the result. 
Result so far: 11158.0
Subtracting 5488 from 6157 leaves us with 669.
Append the next digit (5) from the dividend to 669 and continue with: 6695 / 686

Step 8:
The number 686 fits into 6695 9 times, leaving a remainder of 521.
Put 9 as the next digit of the answer. 
Result so far: 111589.0
Subtracting 6174 from 6695 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 9:
686 can be fit into 5210 7 times, resulting in a remainder of 408.
Put 7 as the next digit of the answer. 
Result so far: 111589.7
Deduct 4802 from 5210 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
686 can be fit into 4080 5 times, resulting in a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 111589.75
If we subtract 3430 from 4080, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 11:
6500 divided by 686 is 9 with a remainder of 326.
Use 9 as the next digit of our solution. 
Result so far: 111589.759
The remainder is 326 after subtracting 6174 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 12:
When dividing 3260 by 686, we get 4 with a remainder of 516.
The next digit of our result is 4. 
Result so far: 111589.7594
Deduct 2744 from 3260 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 13:
If we divide 5160 by 686, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 111589.75947
Subtract 4802 from 5160 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 14:
When dividing 3580 by 686, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 111589.759475
If we take 3430 away from 3580, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
1500 divided by 686 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 111589.7594752
If we subtract 1372 from 1500, we get 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 16:
1280 divided by 686 is 1 with a remainder of 594.
Write down 1 as next digit of the result. 
Result so far: 111589.75947521
If we subtract 686 from 1280, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

In conclusion, the division gives 111589.75947521 with a balance of 5.94e-07.
