We divide 128973 by 78
We want to figure out the number of times 128973 can be divided by 78.

Advancing to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 78

Moving on to step 2:
The number 78 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 78

Advancing to step 3:
128 divided by 78 is 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 128, we get 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 78

Going ahead to step 4:
78 can be fit into 509 6 times, resulting in a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 468 from 509 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 78

Moving on to step 5:
When dividing 417 by 78, we get 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 165.0
Subtracting 390 from 417 leaves us with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 78

On to step 6:
273 divided by 78 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 1653.0
If we take 234 away from 273, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
78 goes into 390 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1653.5
The remainder is 0 after subtracting 390 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 78, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1653.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
78 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1653.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1653.5 with a remaining 0.0.
