We're dividing 77501002 by 686 
Our goal is to divide 77501002 by 686.

Advancing to step 1:
7 divided by 686 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 686

Let's proceed to step 2:
77 divided by 686 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 686

Step 3:
The number 686 fits into 775 1 times, leaving a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 686 away from 775, we end up with 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 686

On to step 4:
686 goes into 890 1 times with a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 686 from 890 leaves us with 204.
Fetch the next digit (1) from the dividend, attach it to 204 and continue: 2041 / 686

Advancing to step 5:
2041 divided by 686 is 2 with a remainder of 669.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 1372 from 2041 to get 669.
Include the next digit (0) from the dividend after 669, then repeat: 6690 / 686

Step 6:
When dividing 6690 by 686, we get 9 with a remainder of 516.
Put 9 as the next digit of the answer. 
Result so far: 1129.0
If we take 6174 away from 6690, we end up with 516.
Append the next digit (0) from the dividend to 516 and continue with: 5160 / 686

Advancing to step 7:
When dividing 5160 by 686, we get 7 with a remainder of 358.
Record the quotient 7 as the next digit in the result. 
Result so far: 11297.0
Subtracting 4802 from 5160 leaves us with 358.
Grab the next digit (2) from the dividend, add it to 358, then carry on: 3582 / 686

Moving on to step 8:
If we divide 3582 by 686, we get 5 and a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 112975.0
Deduct 3430 from 3582 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
When dividing 1520 by 686, we get 2 with a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 112975.2
The remainder is 148 after subtracting 1372 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 10:
If we divide 1480 by 686, we get 2 and a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 112975.22
Subtracting 1372 from 1480 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 112975.22 and a remainder of 0.108.
