603988 divided by 77 
Our goal is to divide 603988 by 77.

Going ahead to step 1:
77 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 77

On to step 2:
77 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 77

Going ahead to step 3:
If we divide 603 by 77, we get 7 and a remainder of 64.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 539 from 603 and we're left with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 77

Going ahead to step 4:
The number 77 fits into 649 8 times, leaving a remainder of 33.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 616 from 649 and we're left with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 77

Advancing to step 5:
77 can be fit into 338 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Subtract 308 from 338 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 77

Advancing to step 6:
If we divide 308 by 77, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 7844.0
If we take 308 away from 308, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
77 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7844.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 77, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7844.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7844.0 with a remaining 0.0.
