We're dividing 28875210 by 523 
We want to figure out the number of times 28875210 can be divided by 523.

Step 1:
523 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 523

Advancing to step 2:
If we divide 28 by 523, we get 0 and 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 (8) from the dividend after 28, then repeat: 288 / 523

Moving on to step 3:
The number 523 fits into 288 0 times, leaving a remainder of 288.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Fetch the next digit (7) from the dividend, attach it to 288 and continue: 2887 / 523

Advancing to step 4:
If we divide 2887 by 523, we get 5 and a remainder of 272.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2615 from 2887 leaves us with 272.
Fetch the next digit (5) from the dividend, attach it to 272 and continue: 2725 / 523

Going ahead to step 5:
523 can be fit into 2725 5 times, resulting in a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 2615 from 2725, we get 110.
Grab the next digit (2) from the dividend, add it to 110, then carry on: 1102 / 523

Moving on to step 6:
If we divide 1102 by 523, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 552.0
If we take 1046 away from 1102, we end up with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 523

Moving on to step 7:
523 goes into 561 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 5521.0
Subtracting 523 from 561 leaves us with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 523

Advancing to step 8:
380 divided by 523 is 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 55210.0
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 9:
3800 divided by 523 is 7 with a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 55210.7
Subtracting 3661 from 3800 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 10:
1390 divided by 523 is 2 with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 55210.72
If we take 1046 away from 1390, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
523 can be fit into 3440 6 times, resulting in a remainder of 302.
Put 6 as the next digit of the answer. 
Result so far: 55210.726
Subtract 3138 from 3440 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 12:
523 can be fit into 3020 5 times, resulting in a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 55210.7265
Deduct 2615 from 3020 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 13:
523 goes into 4050 7 times with a remainder of 389.
Record the quotient 7 as the next digit in the result. 
Result so far: 55210.72657
Deduct 3661 from 4050 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 14:
523 goes into 3890 7 times with a remainder of 229.
Write down 7 as next digit of the result. 
Result so far: 55210.726577
The remainder is 229 after subtracting 3661 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Our division results in 55210.726577 with a remaining 2.29e-05.
