We look at the division of 609574 by 78 
Let's see how many times 78 fits into 609574.

Moving on to step 1:
78 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 78

Going ahead to step 2:
78 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 78

On to step 3:
78 goes into 609 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 546 from 609 and we're left with 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 78

Let's proceed to step 4:
78 can be fit into 635 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 11 after subtracting 624 from 635.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 78

Let's proceed to step 5:
78 can be fit into 117 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 781.0
Subtract 78 from 117 to get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 78

Let's proceed to step 6:
The number 78 fits into 394 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 7815.0
If we subtract 390 from 394, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7815.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 78, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7815.05
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 7815.051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 7815.0512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7815.05128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7815.051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7815.051282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
400 divided by 78 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7815.05128205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 7815.05128205 with a remainder of 1e-08.
