We look at the division of 84209477 by 779 
Our goal is to divide 84209477 by 779.

On to step 1:
The number 779 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 779

Moving on to step 2:
84 divided by 779 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 779

Step 3:
779 goes into 842 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 779 from 842 to get 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 779

Advancing to step 4:
779 can be fit into 630 0 times, resulting in a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 630, we get 630.
Include the next digit (9) from the dividend after 630, then repeat: 6309 / 779

Moving on to step 5:
779 can be fit into 6309 8 times, resulting in a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 6232 from 6309 and we're left with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 779

Moving on to step 6:
The number 779 fits into 774 0 times, leaving a remainder of 774.
Use 0 as the next digit of our solution. 
Result so far: 1080.0
Subtract 0 from 774 to get 774.
Include the next digit (7) from the dividend after 774, then repeat: 7747 / 779

Let's proceed to step 7:
779 can be fit into 7747 9 times, resulting in a remainder of 736.
Write down 9 as next digit of the result. 
Result so far: 10809.0
If we subtract 7011 from 7747, we get 736.
Include the next digit (7) from the dividend after 736, then repeat: 7367 / 779

On to step 8:
779 goes into 7367 9 times with a remainder of 356.
Put 9 as the next digit of the answer. 
Result so far: 108099.0
The remainder is 356 after subtracting 7011 from 7367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 9:
3560 divided by 779 is 4 with a remainder of 444.
The number 4 becomes the next digit in our result. 
Result so far: 108099.4
If we take 3116 away from 3560, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 10:
If we divide 4440 by 779, we get 5 and a remainder of 545.
Use 5 as the next digit of our solution. 
Result so far: 108099.45
Subtracting 3895 from 4440 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 11:
5450 divided by 779 is 6 with a remainder of 776.
Record the quotient 6 as the next digit in the result. 
Result so far: 108099.456
If we take 4674 away from 5450, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 12:
If we divide 7760 by 779, we get 9 and a remainder of 749.
The number 9 becomes the next digit in our result. 
Result so far: 108099.4569
Subtract 7011 from 7760 to get 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Step 13:
779 can be fit into 7490 9 times, resulting in a remainder of 479.
Put 9 as the next digit of the answer. 
Result so far: 108099.45699
If we take 7011 away from 7490, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

After the division, we end up with 108099.45699 and a remainder of 0.000479.
