143843 ÷ 53 
Let's see how many times 53 fits into 143843.

Let's proceed to step 1:
53 goes into 1 0 times with 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.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 53

Step 2:
When dividing 14 by 53, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 53

Moving on to step 3:
When dividing 143 by 53, we get 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 106 from 143 leaves us with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 53

Step 4:
The number 53 fits into 378 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 371 from 378 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 53

Let's proceed to step 5:
The number 53 fits into 74 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 271.0
The remainder is 21 after subtracting 53 from 74.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 53

Going ahead to step 6:
53 goes into 213 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 2714.0
Subtracting 212 from 213 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
53 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2714.0
Deduct 0 from 10 and we're left 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.

Advancing to step 8:
If we divide 100 by 53, we get 1 and a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 2714.01
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
The number 53 fits into 470 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 2714.018
The remainder is 46 after subtracting 424 from 470.
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 10:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 2714.0188
If we subtract 424 from 460, we 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 outcome is 2714.0188, with a leftover of 0.00036.
