We're dividing 63885007 by 771 
We're looking to find how many times 771 goes into 63885007.

Let's proceed to step 1:
When dividing 6 by 771, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 771

On to step 2:
When dividing 63 by 771, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 771

On to step 3:
638 divided by 771 is 0 with a remainder of 638.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 638, we get 638.
Include the next digit (8) from the dividend after 638, then repeat: 6388 / 771

Going ahead to step 4:
771 can be fit into 6388 8 times, resulting in a remainder of 220.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6168 away from 6388, we end up with 220.
Fetch the next digit (5) from the dividend, attach it to 220 and continue: 2205 / 771

On to step 5:
If we divide 2205 by 771, we get 2 and a remainder of 663.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 1542 from 2205 and we're left with 663.
Include the next digit (0) from the dividend after 663, then repeat: 6630 / 771

Going ahead to step 6:
6630 divided by 771 is 8 with a remainder of 462.
Write down 8 as next digit of the result. 
Result so far: 828.0
Subtract 6168 from 6630 to get 462.
Fetch the next digit (0) from the dividend, attach it to 462 and continue: 4620 / 771

Advancing to step 7:
When dividing 4620 by 771, we get 5 with a remainder of 765.
Put 5 as the next digit of the answer. 
Result so far: 8285.0
Subtracting 3855 from 4620 leaves us with 765.
Include the next digit (7) from the dividend after 765, then repeat: 7657 / 771

Advancing to step 8:
771 can be fit into 7657 9 times, resulting in a remainder of 718.
Record the quotient 9 as the next digit in the result. 
Result so far: 82859.0
Deduct 6939 from 7657 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Going ahead to step 9:
The number 771 fits into 7180 9 times, leaving a remainder of 241.
Record the quotient 9 as the next digit in the result. 
Result so far: 82859.9
Deduct 6939 from 7180 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 10:
When dividing 2410 by 771, we get 3 with a remainder of 97.
The next digit of our result is 3. 
Result so far: 82859.93
The remainder is 97 after subtracting 2313 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 11:
If we divide 970 by 771, we get 1 and a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 82859.931
Subtracting 771 from 970 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 12:
771 can be fit into 1990 2 times, resulting in a remainder of 448.
The number 2 becomes the next digit in our result. 
Result so far: 82859.9312
Subtract 1542 from 1990 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 13:
771 goes into 4480 5 times with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 82859.93125
Subtracting 3855 from 4480 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 14:
The number 771 fits into 6250 8 times, leaving a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 82859.931258
If we subtract 6168 from 6250, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 15:
820 divided by 771 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 82859.9312581
Subtracting 771 from 820 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 16:
The number 771 fits into 490 0 times, leaving a remainder of 490.
The next digit of our result is 0. 
Result so far: 82859.9312581
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final outcome is 82859.9312581, with a leftover of 4.9e-07.
