We're dividing 13187384 by 78 
Our goal is to divide 13187384 by 78.

Going ahead to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 78

Let's proceed to step 2:
78 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 78

On to step 3:
78 can be fit into 131 1 times, resulting in a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 131 leaves us with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 78

On to step 4:
The number 78 fits into 538 6 times, leaving a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 468 away from 538, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 78

Moving on to step 5:
78 goes into 707 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
The remainder is 5 after subtracting 702 from 707.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 78

Let's proceed to step 6:
When dividing 53 by 78, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 1690.0
Subtract 0 from 53 to get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 78

Let's proceed to step 7:
78 can be fit into 538 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 16906.0
If we take 468 away from 538, we end up with 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 78

On to step 8:
When dividing 704 by 78, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 169069.0
Deduct 702 from 704 and we're left with 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 9:
If we divide 20 by 78, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 169069.0
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.

Let's proceed to step 10:
78 goes into 200 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 169069.02
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
440 divided by 78 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 169069.025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
500 divided by 78 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 169069.0256
Deduct 468 from 500 and we're left 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.

Step 13:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 169069.02564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
When dividing 80 by 78, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 169069.025641
Subtract 78 from 80 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 15:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 169069.025641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
When dividing 200 by 78, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 169069.02564102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 169069.02564102 and a remainder of 4.4e-08.
