We divide 172843 by 53
Let's see how many times 53 fits into 172843.

Going ahead to step 1:
If we divide 1 by 53, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 53

Going ahead to step 2:
When dividing 17 by 53, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 53

Moving on to step 3:
53 goes into 172 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 159 from 172 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 53

On to step 4:
When dividing 138 by 53, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 32 after subtracting 106 from 138.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 53

Moving on to step 5:
53 goes into 324 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
If we subtract 318 from 324, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 53

Step 6:
When dividing 63 by 53, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 3261.0
If we take 53 away from 63, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 53, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 3261.1
The remainder is 47 after subtracting 53 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
53 goes into 470 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 3261.18
Subtracting 424 from 470 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
If we divide 460 by 53, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 3261.188
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 3261.188 with a remainder of 0.0036.
