Let's divide 43499135 by 53
We're looking to find how many times 53 goes into 43499135.

Advancing to step 1:
53 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 53

Let's proceed to step 2:
53 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 53

On to step 3:
When dividing 434 by 53, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 10 after subtracting 424 from 434.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 53

On to step 4:
If we divide 109 by 53, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 82.0
If we take 106 away from 109, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 53

On to step 5:
If we divide 39 by 53, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 820.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 53

Advancing to step 6:
The number 53 fits into 391 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 8207.0
If we subtract 371 from 391, we get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 53

Let's proceed to step 7:
When dividing 203 by 53, we get 3 with a remainder of 44.
The next digit of our result is 3. 
Result so far: 82073.0
If we take 159 away from 203, we end up with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 53

Advancing to step 8:
If we divide 445 by 53, we get 8 and a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 820738.0
Deduct 424 from 445 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
53 goes into 210 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 820738.3
If we subtract 159 from 210, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
When dividing 510 by 53, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 820738.39
The remainder is 33 after subtracting 477 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 11:
The number 53 fits into 330 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 820738.396
The remainder is 12 after subtracting 318 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 53, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 820738.3962
Subtracting 106 from 120 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
53 goes into 140 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 820738.39622
Subtract 106 from 140 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 820738.39622, with a leftover of 3.4e-05.
