We're dividing 53087730 by 685 
Our goal is to divide 53087730 by 685.

Advancing to step 1:
When dividing 5 by 685, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 685

On to step 2:
53 divided by 685 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 685

Step 3:
685 can be fit into 530 0 times, resulting in a remainder of 530.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 530 leaves us with 530.
Fetch the next digit (8) from the dividend, attach it to 530 and continue: 5308 / 685

Let's proceed to step 4:
The number 685 fits into 5308 7 times, leaving a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 4795 from 5308 and we're left with 513.
Take the next digit (7) from the dividend and append it to 513, then repeat: 5137 / 685

Going ahead to step 5:
5137 divided by 685 is 7 with a remainder of 342.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 4795 from 5137 to get 342.
Take the next digit (7) from the dividend and append it to 342, then repeat: 3427 / 685

Advancing to step 6:
When dividing 3427 by 685, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 775.0
Deduct 3425 from 3427 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 685

Moving on to step 7:
The number 685 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 7750.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 685

Going ahead to step 8:
The number 685 fits into 230 0 times, leaving a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 77500.0
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 9:
685 goes into 2300 3 times with a remainder of 245.
Put 3 as the next digit of the answer. 
Result so far: 77500.3
Deduct 2055 from 2300 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
The number 685 fits into 2450 3 times, leaving a remainder of 395.
The next digit of our result is 3. 
Result so far: 77500.33
Subtracting 2055 from 2450 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The quotient of the division is 77500.33, and the remainder is 0.395.
