We're dividing 423630 by 88 
We want to figure out the number of times 423630 can be divided by 88.

Going ahead to step 1:
If we divide 4 by 88, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 88

Advancing to step 2:
The number 88 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
Deduct 0 from 42 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 88

Advancing to step 3:
88 goes into 423 4 times with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 71 after subtracting 352 from 423.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 88

Moving on to step 4:
88 goes into 716 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 704 from 716, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 88

Moving on to step 5:
The number 88 fits into 123 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 481.0
If we subtract 88 from 123, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 88

Moving on to step 6:
88 goes into 350 3 times with a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 4813.0
If we subtract 264 from 350, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 7:
88 goes into 860 9 times with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 4813.9
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
88 can be fit into 680 7 times, resulting in a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 4813.97
If we take 616 away from 680, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
88 goes into 640 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 4813.977
If we take 616 away from 640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 4813.977, and the remainder is 0.0024.
