We're dividing 585138 by 78 
We want to figure out the number of times 585138 can be divided by 78.

Moving on to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 78

Advancing to step 2:
78 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 78

Let's proceed to step 3:
The number 78 fits into 585 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 546 away from 585, we end up with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 78

Let's proceed to step 4:
When dividing 391 by 78, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 390 away from 391, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 78

Step 5:
When dividing 13 by 78, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 750.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 78

Going ahead to step 6:
The number 78 fits into 138 1 times, leaving a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 7501.0
Subtract 78 from 138 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
600 divided by 78 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 7501.7
Subtracting 546 from 600 leaves us with 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 8:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 7501.76
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
720 divided by 78 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 7501.769
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.

Let's proceed to step 10:
When dividing 180 by 78, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7501.7692
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.

Advancing to step 11:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 7501.76923
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.

Going ahead to step 12:
78 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7501.76923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
78 goes into 600 7 times with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7501.7692307
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.

Advancing to step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 7501.76923076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 7501.76923076 with a balance of 7.2e-08.
