We look at the division of 36665648 by 712 
The aim is to understand the frequency of 712 in 36665648.

Step 1:
If we divide 3 by 712, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 712

Step 2:
36 divided by 712 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 712

Advancing to step 3:
If we divide 366 by 712, we get 0 and a remainder of 366.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 366, we get 366.
Include the next digit (6) from the dividend after 366, then repeat: 3666 / 712

On to step 4:
If we divide 3666 by 712, we get 5 and a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3560 from 3666 and we're left with 106.
Append the next digit (5) from the dividend to 106 and continue with: 1065 / 712

Going ahead to step 5:
When dividing 1065 by 712, we get 1 with a remainder of 353.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 712 from 1065 to get 353.
Grab the next digit (6) from the dividend, add it to 353, then carry on: 3536 / 712

Step 6:
When dividing 3536 by 712, we get 4 with a remainder of 688.
The next digit of our result is 4. 
Result so far: 514.0
The remainder is 688 after subtracting 2848 from 3536.
Include the next digit (4) from the dividend after 688, then repeat: 6884 / 712

Going ahead to step 7:
6884 divided by 712 is 9 with a remainder of 476.
The number 9 becomes the next digit in our result. 
Result so far: 5149.0
If we subtract 6408 from 6884, we get 476.
Include the next digit (8) from the dividend after 476, then repeat: 4768 / 712

Advancing to step 8:
The number 712 fits into 4768 6 times, leaving a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 51496.0
If we subtract 4272 from 4768, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 9:
712 can be fit into 4960 6 times, resulting in a remainder of 688.
The number 6 becomes the next digit in our result. 
Result so far: 51496.6
Deduct 4272 from 4960 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 10:
712 can be fit into 6880 9 times, resulting in a remainder of 472.
Write down 9 as next digit of the result. 
Result so far: 51496.69
If we subtract 6408 from 6880, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 11:
When dividing 4720 by 712, we get 6 with a remainder of 448.
Write down 6 as next digit of the result. 
Result so far: 51496.696
Subtracting 4272 from 4720 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 12:
712 can be fit into 4480 6 times, resulting in a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 51496.6966
Deduct 4272 from 4480 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 51496.6966 and a remainder of 0.00208.
