We're dividing 27331230 by 210 
The aim is to understand the frequency of 210 in 27331230.

Let's proceed to step 1:
If we divide 2 by 210, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 210

Going ahead to step 2:
210 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 210

Advancing to step 3:
The number 210 fits into 273 1 times, leaving a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 210 from 273, we get 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 210

Going ahead to step 4:
633 divided by 210 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 13.0
If we take 630 away from 633, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 210

Moving on to step 5:
210 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 210

Let's proceed to step 6:
312 divided by 210 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 1301.0
Subtract 210 from 312 to get 102.
Bring next digit (3) of the dividend behind the 102 and repeat the process: 1023 / 210

Let's proceed to step 7:
When dividing 1023 by 210, we get 4 with a remainder of 183.
Put 4 as the next digit of the answer. 
Result so far: 13014.0
If we subtract 840 from 1023, we get 183.
Append the next digit (0) from the dividend to 183 and continue with: 1830 / 210

Let's proceed to step 8:
If we divide 1830 by 210, we get 8 and a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 130148.0
Subtracting 1680 from 1830 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
210 can be fit into 1500 7 times, resulting in a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 130148.7
Deduct 1470 from 1500 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 210, we get 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 130148.71
The remainder is 90 after subtracting 210 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
When dividing 900 by 210, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 130148.714
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
210 can be fit into 600 2 times, resulting in a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 130148.7142
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
If we divide 1800 by 210, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 130148.71428
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
If we divide 1200 by 210, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 130148.714285
If we take 1050 away from 1200, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 15:
210 goes into 1500 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 130148.7142857
If we take 1470 away from 1500, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
300 divided by 210 is 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 130148.71428571
Subtracting 210 from 300 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 130148.71428571, with a leftover of 9e-08.
