We look at the division of 63390209 by 771 
Our goal is to divide 63390209 by 771.

On to step 1:
771 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 771

Going ahead to step 2:
When dividing 63 by 771, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 771

Let's proceed to step 3:
If we divide 633 by 771, we get 0 and a remainder of 633.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 633 and we're left with 633.
Take the next digit (9) from the dividend and append it to 633, then repeat: 6339 / 771

On to step 4:
771 goes into 6339 8 times with a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6168 from 6339 to get 171.
Grab the next digit (0) from the dividend, add it to 171, then carry on: 1710 / 771

Let's proceed to step 5:
When dividing 1710 by 771, we get 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 1542 from 1710, we get 168.
Append the next digit (2) from the dividend to 168 and continue with: 1682 / 771

Advancing to step 6:
771 goes into 1682 2 times with a remainder of 140.
The next digit of our result is 2. 
Result so far: 822.0
Deduct 1542 from 1682 and we're left with 140.
Bring next digit (0) of the dividend behind the 140 and repeat the process: 1400 / 771

Advancing to step 7:
If we divide 1400 by 771, we get 1 and a remainder of 629.
Record the quotient 1 as the next digit in the result. 
Result so far: 8221.0
Subtracting 771 from 1400 leaves us with 629.
Fetch the next digit (9) from the dividend, attach it to 629 and continue: 6299 / 771

Step 8:
771 goes into 6299 8 times with a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 82218.0
If we subtract 6168 from 6299, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 9:
When dividing 1310 by 771, we get 1 with a remainder of 539.
The number 1 becomes the next digit in our result. 
Result so far: 82218.1
The remainder is 539 after subtracting 771 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 10:
5390 divided by 771 is 6 with a remainder of 764.
The number 6 becomes the next digit in our result. 
Result so far: 82218.16
Subtracting 4626 from 5390 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 11:
The number 771 fits into 7640 9 times, leaving a remainder of 701.
Use 9 as the next digit of our solution. 
Result so far: 82218.169
If we take 6939 away from 7640, we end up with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

On to step 12:
The number 771 fits into 7010 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 82218.1699
Subtract 6939 from 7010 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 82218.1699 with a balance of 0.00071.
