We're dividing 18811133 by 686 
We want to divide 18811133 by 686.

Advancing to step 1:
If we divide 1 by 686, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 686

Advancing to step 2:
686 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 686

Let's proceed to step 3:
If we divide 188 by 686, we get 0 and a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Grab the next digit (1) from the dividend, add it to 188, then carry on: 1881 / 686

Let's proceed to step 4:
686 goes into 1881 2 times with a remainder of 509.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1372 from 1881 to get 509.
Bring next digit (1) of the dividend behind the 509 and repeat the process: 5091 / 686

Advancing to step 5:
686 can be fit into 5091 7 times, resulting in a remainder of 289.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 4802 from 5091, we get 289.
Bring next digit (1) of the dividend behind the 289 and repeat the process: 2891 / 686

On to step 6:
686 goes into 2891 4 times with a remainder of 147.
Write down 4 as next digit of the result. 
Result so far: 274.0
If we take 2744 away from 2891, we end up with 147.
Append the next digit (3) from the dividend to 147 and continue with: 1473 / 686

Moving on to step 7:
686 can be fit into 1473 2 times, resulting in a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 2742.0
Subtract 1372 from 1473 to get 101.
Bring next digit (3) of the dividend behind the 101 and repeat the process: 1013 / 686

Advancing to step 8:
686 can be fit into 1013 1 times, resulting in a remainder of 327.
The next digit of our result is 1. 
Result so far: 27421.0
Deduct 686 from 1013 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
When dividing 3270 by 686, we get 4 with a remainder of 526.
The number 4 becomes the next digit in our result. 
Result so far: 27421.4
The remainder is 526 after subtracting 2744 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
5260 divided by 686 is 7 with a remainder of 458.
Record the quotient 7 as the next digit in the result. 
Result so far: 27421.47
Subtracting 4802 from 5260 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 11:
If we divide 4580 by 686, we get 6 and a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 27421.476
Deduct 4116 from 4580 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 12:
686 goes into 4640 6 times with a remainder of 524.
Record the quotient 6 as the next digit in the result. 
Result so far: 27421.4766
Deduct 4116 from 4640 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final result is 27421.4766 with a remainder of 0.00524.
