423876 divided by 90 
We're looking to find how many times 90 goes into 423876.

Moving on to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 90

Step 2:
The number 90 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 90

Let's proceed to step 3:
90 goes into 423 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 63 after subtracting 360 from 423.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 90

On to step 4:
90 goes into 638 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 630 from 638 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 90

Let's proceed to step 5:
90 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 470.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 90

Going ahead to step 6:
90 can be fit into 876 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 4709.0
The remainder is 66 after subtracting 810 from 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
660 divided by 90 is 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 4709.7
Subtracting 630 from 660 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 4709.73
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 4709.733
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 4709.733 with a balance of 0.003.
