386046 ÷ 90 
We want to figure out the number of times 386046 can be divided by 90.

Step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 90

On to step 2:
38 divided by 90 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 90

Step 3:
When dividing 386 by 90, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 360 from 386 and we're left with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 90

Let's proceed to step 4:
When dividing 260 by 90, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 80 after subtracting 180 from 260.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 90

Advancing to step 5:
90 goes into 804 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Subtracting 720 from 804 leaves us with 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 90

Going ahead to step 6:
90 goes into 846 9 times with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 4289.0
If we take 810 away from 846, 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.

On to step 7:
90 goes into 360 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4289.4
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4289.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
90 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4289.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4289.4, with a leftover of 0.0.
