64690762 ÷ 743 
The aim is to understand the frequency of 743 in 64690762.

Going ahead to step 1:
When dividing 6 by 743, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 743

Advancing to step 2:
The number 743 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 743

Moving on to step 3:
The number 743 fits into 646 0 times, leaving a remainder of 646.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 646, we end up with 646.
Append the next digit (9) from the dividend to 646 and continue with: 6469 / 743

Advancing to step 4:
When dividing 6469 by 743, we get 8 with a remainder of 525.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 5944 from 6469, we get 525.
Fetch the next digit (0) from the dividend, attach it to 525 and continue: 5250 / 743

Going ahead to step 5:
If we divide 5250 by 743, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 5201 from 5250 and we're left with 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 743

Let's proceed to step 6:
If we divide 497 by 743, we get 0 and a remainder of 497.
Use 0 as the next digit of our solution. 
Result so far: 870.0
The remainder is 497 after subtracting 0 from 497.
Fetch the next digit (6) from the dividend, attach it to 497 and continue: 4976 / 743

Going ahead to step 7:
The number 743 fits into 4976 6 times, leaving a remainder of 518.
The number 6 becomes the next digit in our result. 
Result so far: 8706.0
If we take 4458 away from 4976, we end up with 518.
Bring next digit (2) of the dividend behind the 518 and repeat the process: 5182 / 743

Moving on to step 8:
When dividing 5182 by 743, we get 6 with a remainder of 724.
The next digit of our result is 6. 
Result so far: 87066.0
The remainder is 724 after subtracting 4458 from 5182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 9:
When dividing 7240 by 743, we get 9 with a remainder of 553.
The next digit of our result is 9. 
Result so far: 87066.9
The remainder is 553 after subtracting 6687 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 10:
743 goes into 5530 7 times with a remainder of 329.
Record the quotient 7 as the next digit in the result. 
Result so far: 87066.97
Deduct 5201 from 5530 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 11:
The number 743 fits into 3290 4 times, leaving a remainder of 318.
Put 4 as the next digit of the answer. 
Result so far: 87066.974
Subtract 2972 from 3290 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 12:
743 goes into 3180 4 times with a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 87066.9744
If we take 2972 away from 3180, we end up 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 87066.9744 and a remainder of 0.00208.
