We divide 609409 by 77
We want to figure out the number of times 609409 can be divided by 77.

Moving on to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 77

Going ahead to step 2:
77 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 77

Advancing to step 3:
77 goes into 609 7 times with a remainder of 70.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 539 from 609, we get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 77

Let's proceed to step 4:
When dividing 704 by 77, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Deduct 693 from 704 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 77

Moving on to step 5:
If we divide 110 by 77, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 791.0
If we subtract 77 from 110, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 77

Moving on to step 6:
339 divided by 77 is 4 with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 7914.0
The remainder is 31 after subtracting 308 from 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
77 goes into 310 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7914.4
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 77 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7914.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 77, we get 2 and a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 7914.402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
77 goes into 460 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 7914.4025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
When dividing 750 by 77, we get 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 7914.40259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
77 goes into 570 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7914.402597
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
When dividing 310 by 77, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7914.4025974
Subtracting 308 from 310 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7914.4025974
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 7914.4025974 and a remainder of 2e-08.
