Let's divide 143412 by 78
Let's see how many times 78 fits into 143412.

Let's proceed to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 78

Moving on to step 2:
78 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 78

Advancing to step 3:
78 can be fit into 143 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 78 away from 143, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 78

Advancing to step 4:
78 goes into 654 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 624 from 654 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 78

Going ahead to step 5:
If we divide 301 by 78, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we take 234 away from 301, we end up with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 78

Advancing to step 6:
672 divided by 78 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1838.0
If we take 624 away from 672, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
78 goes into 480 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 1838.6
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1838.61
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
When dividing 420 by 78, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1838.615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 1838.6153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
If we divide 660 by 78, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1838.61538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
78 goes into 360 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 1838.615384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 78, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1838.6153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
78 goes into 120 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1838.61538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 1838.61538461 with a remaining 4.2e-08.
