We divide 120057 by 78
Our goal is to divide 120057 by 78.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Going ahead to step 2:
When dividing 12 by 78, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 78

Moving on to step 3:
120 divided by 78 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 120 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 78

Advancing to step 4:
78 goes into 420 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 390 from 420 leaves us with 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 78

Moving on to step 5:
The number 78 fits into 305 3 times, leaving a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Deduct 234 from 305 and we're left with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 78

On to step 6:
78 goes into 717 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 1539.0
Subtract 702 from 717 to 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.

Let's proceed to step 7:
78 can be fit into 150 1 times, resulting in a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1539.1
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:
720 divided by 78 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1539.19
Deduct 702 from 720 and we're left 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 9:
When dividing 180 by 78, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 1539.192
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.

Advancing to step 10:
78 goes into 240 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1539.1923
If we subtract 234 from 240, 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.

Let's proceed to step 11:
When dividing 60 by 78, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1539.1923
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 12:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1539.192307
If we subtract 546 from 600, we 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.

Step 13:
78 goes into 540 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1539.1923076
Subtracting 468 from 540 leaves us 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.

Step 14:
720 divided by 78 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1539.19230769
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 quotient of the division is 1539.19230769, and the remainder is 1.8e-08.
