We look at the division of 102837 by 78 
Our goal is to divide 102837 by 78.

Advancing to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 78

Going ahead to step 2:
If we divide 10 by 78, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 78

Moving on to step 3:
The number 78 fits into 102 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 102 to get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 78

Going ahead to step 4:
The number 78 fits into 248 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 14 after subtracting 234 from 248.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 78

Advancing to step 5:
If we divide 143 by 78, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 78 from 143, we get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 78

Going ahead to step 6:
When dividing 657 by 78, we get 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 1318.0
Deduct 624 from 657 and we're left with 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 7:
The number 78 fits into 330 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 1318.4
The remainder is 18 after subtracting 312 from 330.
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 8:
180 divided by 78 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1318.42
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 9:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1318.423
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.

On to step 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1318.423
Subtract 0 from 60 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.

Step 11:
If we divide 600 by 78, we get 7 and a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 1318.42307
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.

Going ahead to step 12:
78 goes into 540 6 times with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 1318.423076
If we take 468 away from 540, we end up 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.

Let's proceed to step 13:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1318.4230769
Subtracting 702 from 720 leaves us 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.

Going ahead to step 14:
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: 1318.42307692
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.

After the division, we end up with 1318.42307692 and a remainder of 2.4e-08.
