Let's divide 978146 by 78
We want to divide 978146 by 78.

Let's proceed to step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 78

Moving on to step 2:
78 can be fit into 97 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 97 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 78

On to step 3:
The number 78 fits into 198 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 42 after subtracting 156 from 198.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 78

Going ahead to step 4:
78 can be fit into 421 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtracting 390 from 421 leaves us with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 78

Advancing to step 5:
When dividing 314 by 78, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1254.0
If we subtract 312 from 314, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 78

Let's proceed to step 6:
When dividing 26 by 78, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 12540.0
The remainder is 26 after subtracting 0 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
78 goes into 260 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 12540.3
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
260 divided by 78 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 12540.33
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 12540.33, with a leftover of 0.026.
