We look at the division of 290484 by 78 
Let's see how many times 78 fits into 290484.

Step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 78

Moving on to step 2:
29 divided by 78 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 78

Let's proceed to step 3:
The number 78 fits into 290 3 times, leaving a remainder of 56.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 234 from 290, we get 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 78

Going ahead to step 4:
564 divided by 78 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 546 from 564 to get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 78

Step 5:
78 can be fit into 188 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 372.0
Subtract 156 from 188 to get 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 78

Let's proceed to step 6:
If we divide 324 by 78, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 3724.0
Subtracting 312 from 324 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.

Advancing to step 7:
120 divided by 78 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 3724.1
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3724.15
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
78 can be fit into 300 3 times, resulting in a remainder of 66.
The next digit of our result is 3. 
Result so far: 3724.153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
78 goes into 660 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3724.1538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
When dividing 360 by 78, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 3724.15384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3724.153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 78, we get 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3724.1538461
Deduct 78 from 120 and we're left 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.

Going ahead to step 14:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 3724.15384615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3724.15384615, with a leftover of 3e-08.
