26471356 ÷ 210 
The aim is to understand the frequency of 210 in 26471356.

Advancing to step 1:
The number 210 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
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 210

Let's proceed to step 2:
The number 210 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 210

Moving on to step 3:
210 can be fit into 264 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 210 from 264, we get 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 210

Going ahead to step 4:
547 divided by 210 is 2 with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 420 from 547 leaves us with 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 210

Advancing to step 5:
210 can be fit into 1271 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 1260 away from 1271, we end up with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 210

Step 6:
When dividing 113 by 210, we get 0 with a remainder of 113.
Use 0 as the next digit of our solution. 
Result so far: 1260.0
The remainder is 113 after subtracting 0 from 113.
Take the next digit (5) from the dividend and append it to 113, then repeat: 1135 / 210

Moving on to step 7:
1135 divided by 210 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 12605.0
The remainder is 85 after subtracting 1050 from 1135.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 210

Moving on to step 8:
When dividing 856 by 210, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 126054.0
If we subtract 840 from 856, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
210 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 126054.0
Deduct 0 from 160 and we're left with 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 10:
210 can be fit into 1600 7 times, resulting in a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 126054.07
If we take 1470 away from 1600, we end up with 130.
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 11:
210 can be fit into 1300 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 126054.076
If we take 1260 away from 1300, we end up 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.

Going ahead to step 12:
If we divide 400 by 210, we get 1 and a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 126054.0761
Deduct 210 from 400 and we're left 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 13:
210 can be fit into 1900 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 126054.07619
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 210, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 126054.07619
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
1000 divided by 210 is 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 126054.0761904
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.

Going ahead to step 16:
1600 divided by 210 is 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 126054.07619047
If we take 1470 away from 1600, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 126054.07619047 with a remainder of 1.3e-07.
