We're dividing 63402720 by 831 
We want to divide 63402720 by 831.

Going ahead to step 1:
When dividing 6 by 831, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 831

Moving on to step 2:
The number 831 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 831

On to step 3:
When dividing 634 by 831, we get 0 with a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 634 leaves us with 634.
Fetch the next digit (0) from the dividend, attach it to 634 and continue: 6340 / 831

On to step 4:
6340 divided by 831 is 7 with a remainder of 523.
The next digit of our result is 7. 
Result so far: 7.0
If we take 5817 away from 6340, we end up with 523.
Take the next digit (2) from the dividend and append it to 523, then repeat: 5232 / 831

Advancing to step 5:
5232 divided by 831 is 6 with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 4986 from 5232 to get 246.
Grab the next digit (7) from the dividend, add it to 246, then carry on: 2467 / 831

On to step 6:
831 can be fit into 2467 2 times, resulting in a remainder of 805.
The number 2 becomes the next digit in our result. 
Result so far: 762.0
The remainder is 805 after subtracting 1662 from 2467.
Grab the next digit (2) from the dividend, add it to 805, then carry on: 8052 / 831

Step 7:
831 goes into 8052 9 times with a remainder of 573.
Use 9 as the next digit of our solution. 
Result so far: 7629.0
If we subtract 7479 from 8052, we get 573.
Append the next digit (0) from the dividend to 573 and continue with: 5730 / 831

Advancing to step 8:
When dividing 5730 by 831, we get 6 with a remainder of 744.
The number 6 becomes the next digit in our result. 
Result so far: 76296.0
If we take 4986 away from 5730, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 9:
7440 divided by 831 is 8 with a remainder of 792.
The number 8 becomes the next digit in our result. 
Result so far: 76296.8
Deduct 6648 from 7440 and we're left with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 10:
7920 divided by 831 is 9 with a remainder of 441.
The number 9 becomes the next digit in our result. 
Result so far: 76296.89
The remainder is 441 after subtracting 7479 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Going ahead to step 11:
If we divide 4410 by 831, we get 5 and a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 76296.895
Deduct 4155 from 4410 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 12:
When dividing 2550 by 831, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 76296.8953
Subtract 2493 from 2550 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
831 goes into 570 0 times with a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 76296.8953
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 14:
When dividing 5700 by 831, we get 6 with a remainder of 714.
The number 6 becomes the next digit in our result. 
Result so far: 76296.895306
If we take 4986 away from 5700, we end up with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Moving on to step 15:
7140 divided by 831 is 8 with a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 76296.8953068
Deduct 6648 from 7140 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 16:
The number 831 fits into 4920 5 times, leaving a remainder of 765.
The next digit of our result is 5. 
Result so far: 76296.89530685
Subtracting 4155 from 4920 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

The final result is 76296.89530685 with a remainder of 7.65e-07.
