We're dividing 198379 by 78 
Let's see how many times 78 fits into 198379.

Moving on to step 1:
78 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 78

Moving on to step 2:
19 divided by 78 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 78

Advancing to step 3:
If we divide 198 by 78, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 156 from 198 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 78

Moving on to step 4:
78 goes into 423 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 390 from 423 and we're left with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 78

On to step 5:
The number 78 fits into 337 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 254.0
Deduct 312 from 337 and we're left with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 78

On to step 6:
When dividing 259 by 78, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 2543.0
Subtract 234 from 259 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
78 can be fit into 250 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 2543.3
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2543.32
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2543.32
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
78 goes into 400 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2543.3205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 2543.32051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 2543.320512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
When dividing 640 by 78, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2543.3205128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2543.32051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 2543.32051282 with a balance of 4e-09.
