We look at the division of 390624 by 77 
Our goal is to divide 390624 by 77.

Let's proceed to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 77

Let's proceed to step 2:
The number 77 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 77

Step 3:
390 divided by 77 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 5 after subtracting 385 from 390.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 77

Let's proceed to step 4:
77 can be fit into 56 0 times, resulting in a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 56 leaves us with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 77

Advancing to step 5:
562 divided by 77 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
Deduct 539 from 562 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 77

Going ahead to step 6:
77 goes into 234 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 5073.0
Subtract 231 from 234 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5073.0
Subtract 0 from 30 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 8:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 5073.03
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
When dividing 690 by 77, we get 8 with a remainder of 74.
The next digit of our result is 8. 
Result so far: 5073.038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 5073.0389
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
77 goes into 470 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5073.03896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
77 can be fit into 80 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 5073.038961
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
When dividing 30 by 77, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 5073.038961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
77 goes into 300 3 times with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 5073.03896103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 5073.03896103 with a remainder of 6.9e-08.
