We look at the division of 189918 by 78 
Our goal is to divide 189918 by 78.

Step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 78

Moving on to step 2:
The number 78 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 78

Let's proceed to step 3:
If we divide 189 by 78, we get 2 and a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 156 from 189 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 78

Advancing to step 4:
78 can be fit into 339 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 27 after subtracting 312 from 339.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 78

Step 5:
The number 78 fits into 271 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
If we subtract 234 from 271, we get 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 78

Going ahead to step 6:
378 divided by 78 is 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 2434.0
If we take 312 away from 378, 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.

Step 7:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 2434.8
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 2434.84
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.

Step 9:
When dividing 480 by 78, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 2434.846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
78 goes into 120 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 2434.8461
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.

On to step 11:
If we divide 420 by 78, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2434.84615
Subtract 390 from 420 to get 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 12:
78 goes into 300 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 2434.846153
Deduct 234 from 300 and we're left 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.

Step 13:
660 divided by 78 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 2434.8461538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2434.84615384
Subtracting 312 from 360 leaves us 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.

After the division, we end up with 2434.84615384 and a remainder of 4.8e-08.
