We're dividing 77452993 by 603 
We want to divide 77452993 by 603.

Going ahead to step 1:
When dividing 7 by 603, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 603

On to step 2:
603 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 603

Going ahead to step 3:
If we divide 774 by 603, we get 1 and a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 603 from 774 to get 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 603

Going ahead to step 4:
The number 603 fits into 1715 2 times, leaving a remainder of 509.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1206 from 1715 and we're left with 509.
Bring next digit (2) of the dividend behind the 509 and repeat the process: 5092 / 603

On to step 5:
When dividing 5092 by 603, we get 8 with a remainder of 268.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 4824 from 5092, we get 268.
Take the next digit (9) from the dividend and append it to 268, then repeat: 2689 / 603

Advancing to step 6:
If we divide 2689 by 603, we get 4 and a remainder of 277.
The next digit of our result is 4. 
Result so far: 1284.0
Subtract 2412 from 2689 to get 277.
Take the next digit (9) from the dividend and append it to 277, then repeat: 2779 / 603

On to step 7:
2779 divided by 603 is 4 with a remainder of 367.
Use 4 as the next digit of our solution. 
Result so far: 12844.0
If we subtract 2412 from 2779, we get 367.
Fetch the next digit (3) from the dividend, attach it to 367 and continue: 3673 / 603

Moving on to step 8:
3673 divided by 603 is 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 128446.0
The remainder is 55 after subtracting 3618 from 3673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
603 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 128446.0
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 10:
When dividing 5500 by 603, we get 9 with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 128446.09
The remainder is 73 after subtracting 5427 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 11:
603 goes into 730 1 times with a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 128446.091
If we take 603 away from 730, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 12:
603 can be fit into 1270 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 128446.0912
If we take 1206 away from 1270, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
603 can be fit into 640 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 128446.09121
If we subtract 603 from 640, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
603 goes into 370 0 times with a remainder of 370.
The next digit of our result is 0. 
Result so far: 128446.09121
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 15:
603 can be fit into 3700 6 times, resulting in a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 128446.0912106
Deduct 3618 from 3700 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 16:
If we divide 820 by 603, we get 1 and a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 128446.09121061
The remainder is 217 after subtracting 603 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

In conclusion, the division gives 128446.09121061 with a balance of 2.17e-07.
