77456400 ÷ 303 
We want to figure out the number of times 77456400 can be divided by 303.

On to step 1:
If we divide 7 by 303, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 303

On to step 2:
303 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 303

Going ahead to step 3:
774 divided by 303 is 2 with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 606 from 774 and we're left with 168.
Grab the next digit (5) from the dividend, add it to 168, then carry on: 1685 / 303

On to step 4:
303 goes into 1685 5 times with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1515 from 1685 to get 170.
Append the next digit (6) from the dividend to 170 and continue with: 1706 / 303

Advancing to step 5:
303 goes into 1706 5 times with a remainder of 191.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Subtracting 1515 from 1706 leaves us with 191.
Take the next digit (4) from the dividend and append it to 191, then repeat: 1914 / 303

Step 6:
303 can be fit into 1914 6 times, resulting in a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 2556.0
The remainder is 96 after subtracting 1818 from 1914.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 303

Going ahead to step 7:
The number 303 fits into 960 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 25563.0
Deduct 909 from 960 and we're left with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 303

Advancing to step 8:
When dividing 510 by 303, we get 1 with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 255631.0
Deduct 303 from 510 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
If we divide 2070 by 303, we get 6 and a remainder of 252.
The next digit of our result is 6. 
Result so far: 255631.6
The remainder is 252 after subtracting 1818 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 10:
If we divide 2520 by 303, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 255631.68
Subtracting 2424 from 2520 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
The number 303 fits into 960 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 255631.683
Subtract 909 from 960 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
303 can be fit into 510 1 times, resulting in a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 255631.6831
The remainder is 207 after subtracting 303 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 13:
2070 divided by 303 is 6 with a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 255631.68316
The remainder is 252 after subtracting 1818 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
303 can be fit into 2520 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 255631.683168
Deduct 2424 from 2520 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 15:
If we divide 960 by 303, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 255631.6831683
Deduct 909 from 960 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 16:
If we divide 510 by 303, we get 1 and a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 255631.68316831
Subtract 303 from 510 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Our division results in 255631.68316831 with a remaining 2.07e-07.
