We look at the division of 78385077 by 23 
We want to divide 78385077 by 23.

On to step 1:
The number 23 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 23

Let's proceed to step 2:
78 divided by 23 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 69 from 78 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 23

Going ahead to step 3:
The number 23 fits into 93 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 92 from 93, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Let's proceed to step 4:
The number 23 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 340.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 23

Step 5:
If we divide 185 by 23, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 3408.0
If we take 184 away from 185, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 23

Going ahead to step 6:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 34080.0
If we subtract 0 from 10, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 23

Let's proceed to step 7:
23 goes into 107 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 340804.0
Subtracting 92 from 107 leaves us with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 23

Moving on to step 8:
If we divide 157 by 23, we get 6 and a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 3408046.0
The remainder is 19 after subtracting 138 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3408046.8
If we subtract 184 from 190, we get 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 10:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 3408046.82
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 3408046.826
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3408046.826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3408046.82608
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
If we divide 160 by 23, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 3408046.826086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 15:
220 divided by 23 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 3408046.8260869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 16:
130 divided by 23 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3408046.82608695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 3408046.82608695, and the remainder is 1.5e-08.
