12793319 divided by 210 
The aim is to understand the frequency of 210 in 12793319.

Step 1:
The number 210 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 210

Advancing to step 2:
When dividing 12 by 210, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 210

Going ahead to step 3:
The number 210 fits into 127 0 times, leaving a remainder of 127.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Include the next digit (9) from the dividend after 127, then repeat: 1279 / 210

On to step 4:
If we divide 1279 by 210, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 1260 from 1279, we get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 210

On to step 5:
If we divide 193 by 210, we get 0 and a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 193 after subtracting 0 from 193.
Fetch the next digit (3) from the dividend, attach it to 193 and continue: 1933 / 210

Going ahead to step 6:
210 goes into 1933 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 609.0
Subtracting 1890 from 1933 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 210

Step 7:
When dividing 431 by 210, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 6092.0
If we take 420 away from 431, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 210

Step 8:
If we divide 119 by 210, we get 0 and a remainder of 119.
Use 0 as the next digit of our solution. 
Result so far: 60920.0
If we subtract 0 from 119, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
210 can be fit into 1190 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 60920.5
If we take 1050 away from 1190, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
1400 divided by 210 is 6 with a remainder of 140.
The number 6 becomes the next digit in our result. 
Result so far: 60920.56
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
The number 210 fits into 1400 6 times, leaving a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 60920.566
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 60920.566, and the remainder is 0.014.
