28955311 ÷ 423 
We want to figure out the number of times 28955311 can be divided by 423.

Let's proceed to step 1:
2 divided by 423 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 423

Moving on to step 2:
423 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 423

Advancing to step 3:
If we divide 289 by 423, we get 0 and a remainder of 289.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 289, we end up with 289.
Include the next digit (5) from the dividend after 289, then repeat: 2895 / 423

Step 4:
If we divide 2895 by 423, we get 6 and a remainder of 357.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 2538 away from 2895, we end up with 357.
Grab the next digit (5) from the dividend, add it to 357, then carry on: 3575 / 423

Let's proceed to step 5:
The number 423 fits into 3575 8 times, leaving a remainder of 191.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we subtract 3384 from 3575, we get 191.
Grab the next digit (3) from the dividend, add it to 191, then carry on: 1913 / 423

Advancing to step 6:
423 goes into 1913 4 times with a remainder of 221.
Put 4 as the next digit of the answer. 
Result so far: 684.0
Deduct 1692 from 1913 and we're left with 221.
Bring next digit (1) of the dividend behind the 221 and repeat the process: 2211 / 423

Going ahead to step 7:
2211 divided by 423 is 5 with a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 6845.0
The remainder is 96 after subtracting 2115 from 2211.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 423

Step 8:
423 goes into 961 2 times with a remainder of 115.
The number 2 becomes the next digit in our result. 
Result so far: 68452.0
Subtract 846 from 961 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
The number 423 fits into 1150 2 times, leaving a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 68452.2
If we take 846 away from 1150, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 10:
423 goes into 3040 7 times with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 68452.27
Subtracting 2961 from 3040 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 11:
423 goes into 790 1 times with a remainder of 367.
The next digit of our result is 1. 
Result so far: 68452.271
Subtracting 423 from 790 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 12:
423 can be fit into 3670 8 times, resulting in a remainder of 286.
Write down 8 as next digit of the result. 
Result so far: 68452.2718
Deduct 3384 from 3670 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 13:
2860 divided by 423 is 6 with a remainder of 322.
Record the quotient 6 as the next digit in the result. 
Result so far: 68452.27186
If we subtract 2538 from 2860, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 14:
423 can be fit into 3220 7 times, resulting in a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 68452.271867
If we take 2961 away from 3220, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 15:
423 goes into 2590 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 68452.2718676
Deduct 2538 from 2590 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 16:
520 divided by 423 is 1 with a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 68452.27186761
The remainder is 97 after subtracting 423 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Our division results in 68452.27186761 with a remaining 9.7e-08.
