We look at the division of 16679980 by 811 
Let's see how many times 811 fits into 16679980.

Let's proceed to step 1:
1 divided by 811 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 811

On to step 2:
811 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 811

Moving on to step 3:
If we divide 166 by 811, we get 0 and a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 811

Moving on to step 4:
811 goes into 1667 2 times with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1622 from 1667 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 811

Going ahead to step 5:
459 divided by 811 is 0 with a remainder of 459.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 459 and we're left with 459.
Append the next digit (9) from the dividend to 459 and continue with: 4599 / 811

Going ahead to step 6:
4599 divided by 811 is 5 with a remainder of 544.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Subtracting 4055 from 4599 leaves us with 544.
Append the next digit (8) from the dividend to 544 and continue with: 5448 / 811

Let's proceed to step 7:
The number 811 fits into 5448 6 times, leaving a remainder of 582.
The next digit of our result is 6. 
Result so far: 2056.0
Subtract 4866 from 5448 to get 582.
Bring next digit (0) of the dividend behind the 582 and repeat the process: 5820 / 811

Advancing to step 8:
The number 811 fits into 5820 7 times, leaving a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 20567.0
Subtract 5677 from 5820 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
The number 811 fits into 1430 1 times, leaving a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 20567.1
The remainder is 619 after subtracting 811 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 10:
811 goes into 6190 7 times with a remainder of 513.
Record the quotient 7 as the next digit in the result. 
Result so far: 20567.17
Subtracting 5677 from 6190 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Going ahead to step 11:
5130 divided by 811 is 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 20567.176
If we subtract 4866 from 5130, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 12:
If we divide 2640 by 811, we get 3 and a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 20567.1763
Subtract 2433 from 2640 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 13:
If we divide 2070 by 811, we get 2 and a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 20567.17632
Subtracting 1622 from 2070 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 14:
811 can be fit into 4480 5 times, resulting in a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 20567.176325
If we subtract 4055 from 4480, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 15:
811 goes into 4250 5 times with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 20567.1763255
Deduct 4055 from 4250 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final result is 20567.1763255 with a remainder of 1.95e-06.
