We're dividing 64640845 by 771 
Our goal is to divide 64640845 by 771.

Advancing to step 1:
771 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 771

Step 2:
771 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 771

Let's proceed to step 3:
If we divide 646 by 771, we get 0 and a remainder of 646.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 646, we get 646.
Append the next digit (4) from the dividend to 646 and continue with: 6464 / 771

Let's proceed to step 4:
6464 divided by 771 is 8 with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6168 from 6464 and we're left with 296.
Grab the next digit (0) from the dividend, add it to 296, then carry on: 2960 / 771

Advancing to step 5:
The number 771 fits into 2960 3 times, leaving a remainder of 647.
The next digit of our result is 3. 
Result so far: 83.0
Subtract 2313 from 2960 to get 647.
Include the next digit (8) from the dividend after 647, then repeat: 6478 / 771

Going ahead to step 6:
771 goes into 6478 8 times with a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 838.0
Subtracting 6168 from 6478 leaves us with 310.
Bring next digit (4) of the dividend behind the 310 and repeat the process: 3104 / 771

Let's proceed to step 7:
If we divide 3104 by 771, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 8384.0
The remainder is 20 after subtracting 3084 from 3104.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 771

Let's proceed to step 8:
The number 771 fits into 205 0 times, leaving a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 83840.0
If we subtract 0 from 205, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
The number 771 fits into 2050 2 times, leaving a remainder of 508.
Record the quotient 2 as the next digit in the result. 
Result so far: 83840.2
Subtract 1542 from 2050 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 10:
5080 divided by 771 is 6 with a remainder of 454.
The number 6 becomes the next digit in our result. 
Result so far: 83840.26
Deduct 4626 from 5080 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 11:
When dividing 4540 by 771, we get 5 with a remainder of 685.
The next digit of our result is 5. 
Result so far: 83840.265
Deduct 3855 from 4540 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 12:
6850 divided by 771 is 8 with a remainder of 682.
Put 8 as the next digit of the answer. 
Result so far: 83840.2658
Subtract 6168 from 6850 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 13:
6820 divided by 771 is 8 with a remainder of 652.
Write down 8 as next digit of the result. 
Result so far: 83840.26588
Deduct 6168 from 6820 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

After the division, we end up with 83840.26588 and a remainder of 0.000652.
