28313830 ÷ 210 
The aim is to understand the frequency of 210 in 28313830.

Advancing to step 1:
210 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 210

Advancing to step 2:
210 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 210

Moving on to step 3:
210 can be fit into 283 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 73 after subtracting 210 from 283.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 210

On to step 4:
210 goes into 731 3 times with a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 630 from 731 leaves us with 101.
Append the next digit (3) from the dividend to 101 and continue with: 1013 / 210

Step 5:
When dividing 1013 by 210, we get 4 with a remainder of 173.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we subtract 840 from 1013, we get 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 210

On to step 6:
210 goes into 1738 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 1348.0
If we take 1680 away from 1738, we end up with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 210

Going ahead to step 7:
210 goes into 583 2 times with a remainder of 163.
The next digit of our result is 2. 
Result so far: 13482.0
Deduct 420 from 583 and we're left with 163.
Fetch the next digit (0) from the dividend, attach it to 163 and continue: 1630 / 210

On to step 8:
If we divide 1630 by 210, we get 7 and a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 134827.0
The remainder is 160 after subtracting 1470 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 9:
1600 divided by 210 is 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 134827.7
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
If we divide 1300 by 210, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 134827.76
The remainder is 40 after subtracting 1260 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 210 fits into 400 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 134827.761
Subtracting 210 from 400 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
When dividing 1900 by 210, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 134827.7619
The remainder is 10 after subtracting 1890 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 210 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 134827.7619
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
210 goes into 1000 4 times with a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 134827.761904
If we subtract 840 from 1000, 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.

Step 15:
The number 210 fits into 1600 7 times, leaving a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 134827.7619047
Subtract 1470 from 1600 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 16:
When dividing 1300 by 210, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 134827.76190476
Deduct 1260 from 1300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 134827.76190476 with a remainder of 4e-08.
