We look at the division of 138343 by 53 
We're looking to find how many times 53 goes into 138343.

Step 1:
53 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 53

Let's proceed to step 2:
When dividing 13 by 53, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 53

Advancing to step 3:
138 divided by 53 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 106 from 138 and we're left with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 53

Let's proceed to step 4:
323 divided by 53 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 318 from 323 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 53

Going ahead to step 5:
53 can be fit into 54 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we take 53 away from 54, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 53

On to step 6:
53 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 2610.0
The remainder is 13 after subtracting 0 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
53 can be fit into 130 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2610.2
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 53, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2610.24
The remainder is 28 after subtracting 212 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 53 fits into 280 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 2610.245
If we take 265 away from 280, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 53, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2610.2452
Subtracting 106 from 150 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
53 can be fit into 440 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2610.24528
The remainder is 16 after subtracting 424 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 53 fits into 160 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 2610.245283
The remainder is 1 after subtracting 159 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
If we divide 10 by 53, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2610.245283
Subtracting 0 from 10 leaves us 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.

On to step 14:
The number 53 fits into 100 1 times, leaving a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 2610.24528301
Deduct 53 from 100 and we're left 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.

The final outcome is 2610.24528301, with a leftover of 4.7e-08.
