173446 divided by 78 
Let's see how many times 78 fits into 173446.

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
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 78

Moving on to step 2:
17 divided by 78 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 78

Advancing to step 3:
173 divided by 78 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 17 after subtracting 156 from 173.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 78

Step 4:
The number 78 fits into 174 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 156 away from 174, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 78

Let's proceed to step 5:
78 can be fit into 184 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
If we take 156 away from 184, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 78

On to step 6:
If we divide 286 by 78, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 2223.0
Subtract 234 from 286 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
78 can be fit into 520 6 times, resulting in a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 2223.6
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
The number 78 fits into 520 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 2223.66
If we take 468 away from 520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 2223.66 with a remainder of 0.052.
