58378587 ÷ 78 
Our goal is to divide 58378587 by 78.

Moving on to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 78

Moving on to step 2:
When dividing 58 by 78, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 78

Advancing to step 3:
78 goes into 583 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 546 from 583, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 78

Step 4:
When dividing 377 by 78, we get 4 with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 312 from 377 to get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 78

On to step 5:
658 divided by 78 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 748.0
The remainder is 34 after subtracting 624 from 658.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 78

Let's proceed to step 6:
78 goes into 345 4 times with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 7484.0
Subtract 312 from 345 to get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 78

Let's proceed to step 7:
If we divide 338 by 78, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 74844.0
Subtract 312 from 338 to get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 78

Going ahead to step 8:
If we divide 267 by 78, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 748443.0
Subtract 234 from 267 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 78, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 748443.4
Subtract 312 from 330 to 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.

Step 10:
If we divide 180 by 78, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 748443.42
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.

Moving on to step 11:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 748443.423
Deduct 234 from 240 and we're left 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 12:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 748443.423
If we subtract 0 from 60, we 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.

On to step 13:
78 goes into 600 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 748443.42307
Deduct 546 from 600 and we're left 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.

Step 14:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 748443.423076
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.

Going ahead to step 15:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 748443.4230769
Subtract 702 from 720 to 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.

Step 16:
78 goes into 180 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 748443.42307692
Subtract 156 from 180 to get 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 quotient of the division is 748443.42307692, and the remainder is 2.4e-08.
