77783342 ÷ 578 
Let's see how many times 578 fits into 77783342.

Step 1:
The number 578 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 578

Going ahead to step 2:
578 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 578

On to step 3:
When dividing 777 by 578, we get 1 with a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 578 from 777 leaves us with 199.
Bring next digit (8) of the dividend behind the 199 and repeat the process: 1998 / 578

Step 4:
The number 578 fits into 1998 3 times, leaving a remainder of 264.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1734 away from 1998, we end up with 264.
Include the next digit (3) from the dividend after 264, then repeat: 2643 / 578

Moving on to step 5:
578 goes into 2643 4 times with a remainder of 331.
The next digit of our result is 4. 
Result so far: 134.0
Subtracting 2312 from 2643 leaves us with 331.
Take the next digit (3) from the dividend and append it to 331, then repeat: 3313 / 578

On to step 6:
578 can be fit into 3313 5 times, resulting in a remainder of 423.
The number 5 becomes the next digit in our result. 
Result so far: 1345.0
The remainder is 423 after subtracting 2890 from 3313.
Bring next digit (4) of the dividend behind the 423 and repeat the process: 4234 / 578

On to step 7:
If we divide 4234 by 578, we get 7 and a remainder of 188.
The next digit of our result is 7. 
Result so far: 13457.0
If we subtract 4046 from 4234, we get 188.
Include the next digit (2) from the dividend after 188, then repeat: 1882 / 578

Step 8:
The number 578 fits into 1882 3 times, leaving a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 134573.0
If we take 1734 away from 1882, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 9:
The number 578 fits into 1480 2 times, leaving a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 134573.2
Subtracting 1156 from 1480 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
578 can be fit into 3240 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 134573.25
Deduct 2890 from 3240 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
578 can be fit into 3500 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 134573.256
Subtracting 3468 from 3500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
578 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 134573.256
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
3200 divided by 578 is 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 134573.25605
If we subtract 2890 from 3200, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 14:
When dividing 3100 by 578, we get 5 with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 134573.256055
Deduct 2890 from 3100 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 134573.256055 with a remainder of 2.1e-05.
