603450 divided by 77 
Our goal is to divide 603450 by 77.

Step 1:
The number 77 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 77

Let's proceed to step 2:
The number 77 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 77

On to step 3:
If we divide 603 by 77, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 64 after subtracting 539 from 603.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 77

Let's proceed to step 4:
When dividing 644 by 77, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 616 away from 644, we end up with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 77

Advancing to step 5:
77 goes into 285 3 times with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 783.0
Deduct 231 from 285 and we're left with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 77

Let's proceed to step 6:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7837.0
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 77, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7837.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 77 fits into 100 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 7837.01
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 7837.012
Subtract 154 from 230 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 7837.0129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
The number 77 fits into 670 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 7837.01298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7837.012987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
When dividing 10 by 77, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7837.012987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 77, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 7837.01298701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 7837.01298701, with a leftover of 2.3e-08.
