457347 ÷ 78 
We want to figure out the number of times 457347 can be divided by 78.

Let's proceed to step 1:
78 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 78

Advancing to step 2:
78 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 78

Advancing to step 3:
457 divided by 78 is 5 with a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 390 from 457, we get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 78

Let's proceed to step 4:
When dividing 673 by 78, we get 8 with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we take 624 away from 673, we end up with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 78

Going ahead to step 5:
When dividing 494 by 78, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 586.0
Subtracting 468 from 494 leaves us with 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 78

Advancing to step 6:
78 can be fit into 267 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 5863.0
If we take 234 away from 267, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
If we divide 330 by 78, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 5863.4
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
78 goes into 180 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 5863.42
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 5863.423
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5863.423
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
78 goes into 600 7 times with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 5863.42307
If we subtract 546 from 600, 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.

Moving on to step 12:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 5863.423076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 5863.4230769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
When dividing 180 by 78, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 5863.42307692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 5863.42307692, with a leftover of 2.4e-08.
