151236 divided by 78 
We want to divide 151236 by 78.

Advancing to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 78

Going ahead to step 2:
78 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 78

Let's proceed to step 3:
When dividing 151 by 78, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 78 away from 151, we end up with 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 78

Let's proceed to step 4:
The number 78 fits into 732 9 times, leaving a remainder of 30.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 702 from 732, we get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 78

Let's proceed to step 5:
If we divide 303 by 78, we get 3 and a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Deduct 234 from 303 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 78

Moving on to step 6:
78 goes into 696 8 times with a remainder of 72.
The next digit of our result is 8. 
Result so far: 1938.0
If we take 624 away from 696, 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.

Advancing to step 7:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1938.9
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.

On to step 8:
78 goes into 180 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1938.92
Deduct 156 from 180 and we're left 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.

Let's proceed to step 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 1938.923
If we take 234 away from 240, we end up 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.

Advancing to step 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1938.923
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 11:
78 goes into 600 7 times with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1938.92307
Subtract 546 from 600 to get 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:
When dividing 540 by 78, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 1938.923076
The remainder is 72 after subtracting 468 from 540.
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 13:
78 goes into 720 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1938.9230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 1938.92307692
Subtracting 156 from 180 leaves us 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.

The final result is 1938.92307692 with a remainder of 2.4e-08.
