We're dividing 68309513 by 763 
We want to figure out the number of times 68309513 can be divided by 763.

Advancing to step 1:
The number 763 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 763

On to step 2:
763 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 763

Step 3:
If we divide 683 by 763, we get 0 and a remainder of 683.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 683 and we're left with 683.
Include the next digit (0) from the dividend after 683, then repeat: 6830 / 763

Let's proceed to step 4:
The number 763 fits into 6830 8 times, leaving a remainder of 726.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6104 from 6830 leaves us with 726.
Bring next digit (9) of the dividend behind the 726 and repeat the process: 7269 / 763

Advancing to step 5:
763 goes into 7269 9 times with a remainder of 402.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 6867 from 7269, we get 402.
Take the next digit (5) from the dividend and append it to 402, then repeat: 4025 / 763

Advancing to step 6:
If we divide 4025 by 763, we get 5 and a remainder of 210.
The next digit of our result is 5. 
Result so far: 895.0
Subtracting 3815 from 4025 leaves us with 210.
Bring next digit (1) of the dividend behind the 210 and repeat the process: 2101 / 763

Let's proceed to step 7:
763 can be fit into 2101 2 times, resulting in a remainder of 575.
Put 2 as the next digit of the answer. 
Result so far: 8952.0
If we subtract 1526 from 2101, we get 575.
Fetch the next digit (3) from the dividend, attach it to 575 and continue: 5753 / 763

Let's proceed to step 8:
When dividing 5753 by 763, we get 7 with a remainder of 412.
Use 7 as the next digit of our solution. 
Result so far: 89527.0
Subtract 5341 from 5753 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 9:
763 goes into 4120 5 times with a remainder of 305.
The next digit of our result is 5. 
Result so far: 89527.5
Subtract 3815 from 4120 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 10:
If we divide 3050 by 763, we get 3 and a remainder of 761.
Use 3 as the next digit of our solution. 
Result so far: 89527.53
Subtract 2289 from 3050 to get 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Advancing to step 11:
When dividing 7610 by 763, we get 9 with a remainder of 743.
The next digit of our result is 9. 
Result so far: 89527.539
If we take 6867 away from 7610, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 12:
If we divide 7430 by 763, we get 9 and a remainder of 563.
The number 9 becomes the next digit in our result. 
Result so far: 89527.5399
Subtracting 6867 from 7430 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

The final result is 89527.5399 with a remainder of 0.00563.
