28301693 ÷ 523 
We're looking to find how many times 523 goes into 28301693.

Step 1:
The number 523 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 523

Advancing to step 2:
523 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 523

Going ahead to step 3:
If we divide 283 by 523, we get 0 and a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 283 to get 283.
Take the next digit (0) from the dividend and append it to 283, then repeat: 2830 / 523

On to step 4:
The number 523 fits into 2830 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 2615 away from 2830, we end up with 215.
Fetch the next digit (1) from the dividend, attach it to 215 and continue: 2151 / 523

Step 5:
523 goes into 2151 4 times with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we subtract 2092 from 2151, we get 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 523

Advancing to step 6:
523 goes into 596 1 times with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 541.0
Subtract 523 from 596 to get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 523

On to step 7:
523 goes into 739 1 times with a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 5411.0
Subtract 523 from 739 to get 216.
Take the next digit (3) from the dividend and append it to 216, then repeat: 2163 / 523

Moving on to step 8:
523 can be fit into 2163 4 times, resulting in a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 54114.0
Deduct 2092 from 2163 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
When dividing 710 by 523, we get 1 with a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 54114.1
If we take 523 away from 710, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 10:
If we divide 1870 by 523, we get 3 and a remainder of 301.
The next digit of our result is 3. 
Result so far: 54114.13
The remainder is 301 after subtracting 1569 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 11:
When dividing 3010 by 523, we get 5 with a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 54114.135
Subtracting 2615 from 3010 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 12:
When dividing 3950 by 523, we get 7 with a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 54114.1357
Deduct 3661 from 3950 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 13:
If we divide 2890 by 523, we get 5 and a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 54114.13575
Subtract 2615 from 2890 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 14:
If we divide 2750 by 523, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 54114.135755
Subtract 2615 from 2750 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 54114.135755 and a remainder of 1.35e-05.
