We look at the division of 63906856 by 778 
We want to figure out the number of times 63906856 can be divided by 778.

Going ahead to step 1:
When dividing 6 by 778, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 778

Moving on to step 2:
When dividing 63 by 778, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 778

Step 3:
The number 778 fits into 639 0 times, leaving a remainder of 639.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 639, we get 639.
Fetch the next digit (0) from the dividend, attach it to 639 and continue: 6390 / 778

Let's proceed to step 4:
778 goes into 6390 8 times with a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6224 from 6390 and we're left with 166.
Bring next digit (6) of the dividend behind the 166 and repeat the process: 1666 / 778

On to step 5:
778 goes into 1666 2 times with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 1556 from 1666 to get 110.
Append the next digit (8) from the dividend to 110 and continue with: 1108 / 778

On to step 6:
When dividing 1108 by 778, we get 1 with a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 821.0
The remainder is 330 after subtracting 778 from 1108.
Append the next digit (5) from the dividend to 330 and continue with: 3305 / 778

Let's proceed to step 7:
When dividing 3305 by 778, we get 4 with a remainder of 193.
Put 4 as the next digit of the answer. 
Result so far: 8214.0
Deduct 3112 from 3305 and we're left with 193.
Append the next digit (6) from the dividend to 193 and continue with: 1936 / 778

Going ahead to step 8:
778 goes into 1936 2 times with a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 82142.0
The remainder is 380 after subtracting 1556 from 1936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 9:
When dividing 3800 by 778, we get 4 with a remainder of 688.
Use 4 as the next digit of our solution. 
Result so far: 82142.4
The remainder is 688 after subtracting 3112 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 10:
When dividing 6880 by 778, we get 8 with a remainder of 656.
The number 8 becomes the next digit in our result. 
Result so far: 82142.48
Subtract 6224 from 6880 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 11:
6560 divided by 778 is 8 with a remainder of 336.
The next digit of our result is 8. 
Result so far: 82142.488
If we take 6224 away from 6560, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 82142.488, with a leftover of 0.0336.
