Let's divide 784065 by 78
We want to figure out the number of times 784065 can be divided by 78.

Step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 78

Step 2:
78 goes into 78 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 78 away from 78, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 78

Advancing to step 3:
When dividing 4 by 78, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 78

Let's proceed to step 4:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 40, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 78

Step 5:
If we divide 406 by 78, we get 5 and a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
The remainder is 16 after subtracting 390 from 406.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 78

Advancing to step 6:
165 divided by 78 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 10052.0
Deduct 156 from 165 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 78 fits into 90 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 10052.1
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 78, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 10052.11
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 10052.11, with a leftover of 0.042.
