68617668 ÷ 744 
The aim is to understand the frequency of 744 in 68617668.

Step 1:
If we divide 6 by 744, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 744

On to step 2:
If we divide 68 by 744, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 744

Step 3:
The number 744 fits into 686 0 times, leaving a remainder of 686.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 686 and we're left with 686.
Bring next digit (1) of the dividend behind the 686 and repeat the process: 6861 / 744

Step 4:
744 can be fit into 6861 9 times, resulting in a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 6696 from 6861 and we're left with 165.
Include the next digit (7) from the dividend after 165, then repeat: 1657 / 744

Going ahead to step 5:
744 can be fit into 1657 2 times, resulting in a remainder of 169.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we take 1488 away from 1657, we end up with 169.
Grab the next digit (6) from the dividend, add it to 169, then carry on: 1696 / 744

Let's proceed to step 6:
If we divide 1696 by 744, we get 2 and a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 922.0
If we subtract 1488 from 1696, we get 208.
Append the next digit (6) from the dividend to 208 and continue with: 2086 / 744

Moving on to step 7:
744 goes into 2086 2 times with a remainder of 598.
Record the quotient 2 as the next digit in the result. 
Result so far: 9222.0
Subtracting 1488 from 2086 leaves us with 598.
Append the next digit (8) from the dividend to 598 and continue with: 5988 / 744

Let's proceed to step 8:
The number 744 fits into 5988 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 92228.0
If we subtract 5952 from 5988, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 744, we get 0 and a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 92228.0
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
If we divide 3600 by 744, we get 4 and a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 92228.04
Subtract 2976 from 3600 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Moving on to step 11:
If we divide 6240 by 744, we get 8 and a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 92228.048
The remainder is 288 after subtracting 5952 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
When dividing 2880 by 744, we get 3 with a remainder of 648.
The number 3 becomes the next digit in our result. 
Result so far: 92228.0483
If we take 2232 away from 2880, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 13:
744 can be fit into 6480 8 times, resulting in a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 92228.04838
If we take 5952 away from 6480, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 14:
If we divide 5280 by 744, we get 7 and a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 92228.048387
Deduct 5208 from 5280 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
720 divided by 744 is 0 with a remainder of 720.
The next digit of our result is 0. 
Result so far: 92228.048387
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 16:
When dividing 7200 by 744, we get 9 with a remainder of 504.
Record the quotient 9 as the next digit in the result. 
Result so far: 92228.04838709
The remainder is 504 after subtracting 6696 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 92228.04838709 with a remainder of 5.04e-07.
