We look at the division of 16813980 by 771 
We want to divide 16813980 by 771.

Step 1:
The number 771 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 771

Step 2:
16 divided by 771 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 771

Let's proceed to step 3:
771 can be fit into 168 0 times, resulting in a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 168 after subtracting 0 from 168.
Include the next digit (1) from the dividend after 168, then repeat: 1681 / 771

Moving on to step 4:
1681 divided by 771 is 2 with a remainder of 139.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 139 after subtracting 1542 from 1681.
Include the next digit (3) from the dividend after 139, then repeat: 1393 / 771

Going ahead to step 5:
The number 771 fits into 1393 1 times, leaving a remainder of 622.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 771 from 1393, we get 622.
Take the next digit (9) from the dividend and append it to 622, then repeat: 6229 / 771

Advancing to step 6:
When dividing 6229 by 771, we get 8 with a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 218.0
The remainder is 61 after subtracting 6168 from 6229.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 771

Advancing to step 7:
771 goes into 618 0 times with a remainder of 618.
Write down 0 as next digit of the result. 
Result so far: 2180.0
The remainder is 618 after subtracting 0 from 618.
Take the next digit (0) from the dividend and append it to 618, then repeat: 6180 / 771

Going ahead to step 8:
If we divide 6180 by 771, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 21808.0
If we subtract 6168 from 6180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 771 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 21808.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
771 can be fit into 1200 1 times, resulting in a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 21808.01
Subtracting 771 from 1200 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 11:
771 goes into 4290 5 times with a remainder of 435.
The next digit of our result is 5. 
Result so far: 21808.015
Deduct 3855 from 4290 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 12:
If we divide 4350 by 771, we get 5 and a remainder of 495.
The next digit of our result is 5. 
Result so far: 21808.0155
If we subtract 3855 from 4350, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Our division results in 21808.0155 with a remaining 0.00495.
