28354934 ÷ 320 
We want to figure out the number of times 28354934 can be divided by 320.

Step 1:
If we divide 2 by 320, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 320

On to step 2:
The number 320 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 320

On to step 3:
320 goes into 283 0 times with a remainder of 283.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 283 leaves us with 283.
Fetch the next digit (5) from the dividend, attach it to 283 and continue: 2835 / 320

On to step 4:
2835 divided by 320 is 8 with a remainder of 275.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 2560 away from 2835, we end up with 275.
Bring next digit (4) of the dividend behind the 275 and repeat the process: 2754 / 320

Step 5:
320 can be fit into 2754 8 times, resulting in a remainder of 194.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 2560 from 2754 to get 194.
Include the next digit (9) from the dividend after 194, then repeat: 1949 / 320

Let's proceed to step 6:
320 can be fit into 1949 6 times, resulting in a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 886.0
Subtracting 1920 from 1949 leaves us with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 320

Step 7:
320 goes into 293 0 times with a remainder of 293.
The number 0 becomes the next digit in our result. 
Result so far: 8860.0
Subtracting 0 from 293 leaves us with 293.
Fetch the next digit (4) from the dividend, attach it to 293 and continue: 2934 / 320

Advancing to step 8:
If we divide 2934 by 320, we get 9 and a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 88609.0
Deduct 2880 from 2934 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
320 goes into 540 1 times with a remainder of 220.
The next digit of our result is 1. 
Result so far: 88609.1
If we take 320 away from 540, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
If we divide 2200 by 320, we get 6 and a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 88609.16
The remainder is 280 after subtracting 1920 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
320 can be fit into 2800 8 times, resulting in a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 88609.168
Subtracting 2560 from 2800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
2400 divided by 320 is 7 with a remainder of 160.
The number 7 becomes the next digit in our result. 
Result so far: 88609.1687
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
320 goes into 1600 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 88609.16875
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
When dividing 0 by 320, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 88609.16875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
320 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 88609.16875
Subtract 0 from 0 to get 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 88609.16875 and a remainder of 0.0.
