We look at the division of 189662 by 78 
We want to divide 189662 by 78.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving 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.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 78

On to step 2:
If we divide 18 by 78, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 78

Going ahead to step 3:
When dividing 189 by 78, we get 2 with a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 156 away from 189, we end up with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 78

Going ahead to step 4:
When dividing 336 by 78, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 312 away from 336, we end up with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 78

Step 5:
78 goes into 246 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 243.0
Subtracting 234 from 246 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 78

Moving on to step 6:
122 divided by 78 is 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 2431.0
Subtract 78 from 122 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
78 goes into 440 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2431.5
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 2431.56
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
If we divide 320 by 78, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2431.564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 2431.5641
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2431.5641
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
200 divided by 78 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 2431.564102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 2431.5641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
78 goes into 500 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2431.56410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 2431.56410256 with a remainder of 3.2e-08.
