We look at the division of 174398 by 78 
Our goal is to divide 174398 by 78.

Moving on to step 1:
1 divided by 78 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 78

On to step 2:
17 divided by 78 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 78

Let's proceed to step 3:
78 goes into 174 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 156 from 174, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 78

Step 4:
183 divided by 78 is 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 156 from 183, we get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 78

Going ahead to step 5:
The number 78 fits into 279 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 223.0
If we subtract 234 from 279, we get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 78

On to step 6:
78 goes into 458 5 times with a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 2235.0
Subtracting 390 from 458 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
78 goes into 680 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2235.8
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2235.87
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 78 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 2235.871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 2235.8717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 2235.87179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
78 can be fit into 380 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 2235.871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 2235.8717948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
When dividing 560 by 78, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 2235.87179487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 2235.87179487 with a remainder of 1.4e-08.
