746400 ÷ 68 
The aim is to understand the frequency of 68 in 746400.

Step 1:
If we divide 7 by 68, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 68

Let's proceed to step 2:
If we divide 74 by 68, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 68 from 74 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 68

Moving on to step 3:
The number 68 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 68

Going ahead to step 4:
The number 68 fits into 664 9 times, leaving a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 109.0
The remainder is 52 after subtracting 612 from 664.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 68

Advancing to step 5:
The number 68 fits into 520 7 times, leaving a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 1097.0
Subtracting 476 from 520 leaves us with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 68

Advancing to step 6:
When dividing 440 by 68, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 10976.0
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
68 goes into 320 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 10976.4
If we subtract 272 from 320, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
480 divided by 68 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 10976.47
If we take 476 away from 480, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
68 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10976.47
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 68 fits into 400 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 10976.4705
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 68, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 10976.47058
Deduct 544 from 600 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
560 divided by 68 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10976.470588
If we take 544 away from 560, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 10976.470588, and the remainder is 1.6e-06.
