We look at the division of 439620 by 77 
We want to figure out the number of times 439620 can be divided by 77.

Moving on to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 77

Going ahead to step 2:
77 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 77

Moving on to step 3:
If we divide 439 by 77, we get 5 and a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 385 from 439 and we're left with 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 77

Moving on to step 4:
77 can be fit into 546 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 539 from 546 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 77

On to step 5:
77 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 570.0
Subtract 0 from 72 to get 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 77

Advancing to step 6:
720 divided by 77 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 5709.0
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
270 divided by 77 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 5709.3
The remainder is 39 after subtracting 231 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 77, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5709.35
If we subtract 385 from 390, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 77, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5709.35
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 77 fits into 500 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 5709.3506
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
77 can be fit into 380 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 5709.35064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 77 fits into 720 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 5709.350649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
If we divide 270 by 77, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 5709.3506493
Deduct 231 from 270 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5709.35064935
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 5709.35064935 with a remainder of 5e-09.
