We look at the division of 18643 by 69 
We want to figure out the number of times 18643 can be divided by 69.

On to step 1:
If we divide 1 by 69, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 69

Let's proceed to step 2:
69 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 69

Step 3:
When dividing 186 by 69, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 138 from 186 to get 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 69

Advancing to step 4:
When dividing 484 by 69, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 483 from 484 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 69

On to step 5:
13 divided by 69 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 6:
If we divide 130 by 69, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 270.1
Deduct 69 from 130 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
69 goes into 610 8 times with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 270.18
Subtract 552 from 610 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
580 divided by 69 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 270.188
The remainder is 28 after subtracting 552 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 270.188 and a remainder of 0.0028.
