We're dividing 3078 by 905 
Let's see how many times 905 fits into 3078.

Advancing to step 1:
If we divide 3 by 905, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 905

On to step 2:
When dividing 30 by 905, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 905

On to step 3:
905 can be fit into 307 0 times, resulting in a remainder of 307.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 307 after subtracting 0 from 307.
Grab the next digit (8) from the dividend, add it to 307, then carry on: 3078 / 905

Moving on to step 4:
905 goes into 3078 3 times with a remainder of 363.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2715 from 3078 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 5:
3630 divided by 905 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 3.4
The remainder is 10 after subtracting 3620 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 6:
100 divided by 905 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 3.4
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 7:
905 goes into 1000 1 times with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 3.401
If we take 905 away from 1000, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 8:
950 divided by 905 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 3.4011
The remainder is 45 after subtracting 905 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 3.4011 with a remainder of 0.00045.
