386856 divided by 90 
We want to divide 386856 by 90.

Let's proceed to step 1:
90 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 90

On to step 2:
90 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 90

Going ahead to step 3:
386 divided by 90 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 360 from 386 leaves us with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 90

Let's proceed to step 4:
268 divided by 90 is 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 180 from 268 leaves us with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 90

Moving on to step 5:
When dividing 885 by 90, we get 9 with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 429.0
The remainder is 75 after subtracting 810 from 885.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 90

Going ahead to step 6:
90 can be fit into 756 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 4298.0
If we subtract 720 from 756, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
90 can be fit into 360 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4298.4
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:
90 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4298.4
Subtracting 0 from 0 leaves us 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:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4298.4
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 4298.4 and a remainder of 0.0.
