We're dividing 390052 by 46 
We want to figure out the number of times 390052 can be divided by 46.

On to step 1:
46 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 46

Step 2:
If we divide 39 by 46, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 46

Going ahead to step 3:
46 can be fit into 390 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 368 from 390 to get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 46

Let's proceed to step 4:
The number 46 fits into 220 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 184 from 220 leaves us with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 46

Going ahead to step 5:
If we divide 365 by 46, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 847.0
Deduct 322 from 365 and we're left with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 46

Step 6:
432 divided by 46 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 8479.0
If we take 414 away from 432, 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.

Moving on to step 7:
When dividing 180 by 46, we get 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 8479.3
Deduct 138 from 180 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
420 divided by 46 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 8479.39
Subtract 414 from 420 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 46 fits into 60 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 8479.391
Deduct 46 from 60 and we're left 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.

Advancing to step 10:
46 goes into 140 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 8479.3913
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
20 divided by 46 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8479.3913
Subtracting 0 from 20 leaves us 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.

Advancing to step 12:
46 can be fit into 200 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 8479.391304
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 46 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 8479.3913043
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
46 goes into 220 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8479.39130434
If we take 184 away from 220, we end up with 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 8479.39130434, with a leftover of 3.6e-08.
