Let's divide 603378 by 77
We want to divide 603378 by 77.

On to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 77

Moving on to step 2:
When dividing 60 by 77, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 77

Going ahead to step 3:
When dividing 603 by 77, we get 7 with a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 64 after subtracting 539 from 603.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 77

Moving on to step 4:
When dividing 643 by 77, we get 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 616 from 643 and we're left with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 77

Advancing to step 5:
77 goes into 277 3 times with a remainder of 46.
The next digit of our result is 3. 
Result so far: 783.0
If we take 231 away from 277, we end up with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 77

On to step 6:
77 goes into 468 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 7836.0
Subtracting 462 from 468 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 77, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7836.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
600 divided by 77 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 7836.07
Deduct 539 from 600 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
610 divided by 77 is 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 7836.077
Subtract 539 from 610 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.

The quotient of the division is 7836.077, and the remainder is 0.0071.
