We're dividing 27543611 by 210 
The aim is to understand the frequency of 210 in 27543611.

Step 1:
The number 210 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 210

Going ahead to step 2:
210 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 210

Going ahead to step 3:
When dividing 275 by 210, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 210 from 275 to get 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 210

Going ahead to step 4:
210 goes into 654 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 24 after subtracting 630 from 654.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 210

Step 5:
210 goes into 243 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Deduct 210 from 243 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 210

Let's proceed to step 6:
The number 210 fits into 336 1 times, leaving a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 1311.0
If we subtract 210 from 336, we get 126.
Bring next digit (1) of the dividend behind the 126 and repeat the process: 1261 / 210

Going ahead to step 7:
The number 210 fits into 1261 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 13116.0
Deduct 1260 from 1261 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 210

Moving on to step 8:
210 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 131160.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 210, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 131160.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 131160.05
If we subtract 1050 from 1100, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 210, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 131160.052
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
If we divide 800 by 210, we get 3 and a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 131160.0523
If we take 630 away from 800, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 13:
210 goes into 1700 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 131160.05238
If we take 1680 away from 1700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 210, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 131160.05238
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
210 can be fit into 2000 9 times, resulting in a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 131160.0523809
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 16:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 131160.05238095
If we subtract 1050 from 1100, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 131160.05238095, with a leftover of 5e-08.
