We look at the division of 287601 by 78 
Our goal is to divide 287601 by 78.

Let's proceed to step 1:
2 divided by 78 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 78

Let's proceed to step 2:
If we divide 28 by 78, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 78

Moving on to step 3:
If we divide 287 by 78, we get 3 and a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 287 leaves us with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 78

Moving on to step 4:
The number 78 fits into 536 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 468 from 536 leaves us with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 78

Step 5:
680 divided by 78 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
If we take 624 away from 680, we end up with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 78

Moving on to step 6:
When dividing 561 by 78, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 3687.0
If we subtract 546 from 561, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 78, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 3687.1
The remainder is 72 after subtracting 78 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 3687.19
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.

Advancing to step 9:
If we divide 180 by 78, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3687.192
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.

Advancing to step 10:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3687.1923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3687.1923
Subtracting 0 from 60 leaves us 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.

On to step 12:
600 divided by 78 is 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3687.192307
If we take 546 away from 600, we end up 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.

Moving on to step 13:
When dividing 540 by 78, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 3687.1923076
Subtract 468 from 540 to 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.

Moving on to step 14:
If we divide 720 by 78, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 3687.19230769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 3687.19230769, with a leftover of 1.8e-08.
