We look at the division of 43646 by 52 
Let's see how many times 52 fits into 43646.

Advancing to step 1:
The number 52 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 52

Moving on to step 2:
When dividing 43 by 52, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 52

Advancing to step 3:
When dividing 436 by 52, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 416 from 436, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 52

Moving on to step 4:
52 can be fit into 204 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 83.0
Subtract 156 from 204 to get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 52

Step 5:
When dividing 486 by 52, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 839.0
If we take 468 away from 486, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
52 goes into 180 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 839.3
Subtract 156 from 180 to get 24.
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 7:
If we divide 240 by 52, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 839.34
Deduct 208 from 240 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 52 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 839.346
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
52 goes into 80 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 839.3461
If we subtract 52 from 80, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
280 divided by 52 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 839.34615
If we take 260 away from 280, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 52 is 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 839.346153
Subtracting 156 from 200 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.

Moving on to step 12:
If we divide 440 by 52, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 839.3461538
If we take 416 away from 440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
52 goes into 240 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 839.34615384
If we subtract 208 from 240, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 839.34615384 and a remainder of 3.2e-08.
