Let's divide 78685503 by 649
Let's see how many times 649 fits into 78685503.

Step 1:
7 divided by 649 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 649

Going ahead to step 2:
If we divide 78 by 649, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 649

Advancing to step 3:
649 can be fit into 786 1 times, resulting in a remainder of 137.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 649 from 786 to get 137.
Take the next digit (8) from the dividend and append it to 137, then repeat: 1378 / 649

On to step 4:
649 can be fit into 1378 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 80 after subtracting 1298 from 1378.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 649

Moving on to step 5:
If we divide 805 by 649, we get 1 and a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtracting 649 from 805 leaves us with 156.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 649

Going ahead to step 6:
If we divide 1565 by 649, we get 2 and a remainder of 267.
The number 2 becomes the next digit in our result. 
Result so far: 1212.0
Deduct 1298 from 1565 and we're left with 267.
Fetch the next digit (0) from the dividend, attach it to 267 and continue: 2670 / 649

Moving on to step 7:
If we divide 2670 by 649, we get 4 and a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 12124.0
Subtract 2596 from 2670 to get 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 649

On to step 8:
If we divide 743 by 649, we get 1 and a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 121241.0
Subtracting 649 from 743 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
The number 649 fits into 940 1 times, leaving a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 121241.1
Subtract 649 from 940 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 10:
649 can be fit into 2910 4 times, resulting in a remainder of 314.
The next digit of our result is 4. 
Result so far: 121241.14
If we subtract 2596 from 2910, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 11:
3140 divided by 649 is 4 with a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 121241.144
If we subtract 2596 from 3140, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

After the division, we end up with 121241.144 and a remainder of 0.0544.
