We look at the division of 386305 by 90 
We're looking to find how many times 90 goes into 386305.

Moving on to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 90

Step 2:
90 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 90

On to 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
If we take 360 away from 386, we end up with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 90

Advancing to step 4:
263 divided by 90 is 2 with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 180 from 263 and we're left with 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 90

Moving on to step 5:
90 can be fit into 830 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
The remainder is 20 after subtracting 810 from 830.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 90

Let's proceed to step 6:
The number 90 fits into 205 2 times, leaving a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 4292.0
The remainder is 25 after subtracting 180 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
90 can be fit into 250 2 times, resulting in a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 4292.2
The remainder is 70 after subtracting 180 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 4292.27
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 90 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4292.277
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 4292.277, with a leftover of 0.007.
