We look at the division of 66771689 by 720 
The aim is to understand the frequency of 720 in 66771689.

On to step 1:
If we divide 6 by 720, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 720

Moving on to step 2:
If we divide 66 by 720, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 720

Step 3:
667 divided by 720 is 0 with a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 667 to get 667.
Take the next digit (7) from the dividend and append it to 667, then repeat: 6677 / 720

Let's proceed to step 4:
If we divide 6677 by 720, we get 9 and a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6480 away from 6677, we end up with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 720

Let's proceed to step 5:
1971 divided by 720 is 2 with a remainder of 531.
Put 2 as the next digit of the answer. 
Result so far: 92.0
If we subtract 1440 from 1971, we get 531.
Append the next digit (6) from the dividend to 531 and continue with: 5316 / 720

Moving on to step 6:
5316 divided by 720 is 7 with a remainder of 276.
Record the quotient 7 as the next digit in the result. 
Result so far: 927.0
Subtract 5040 from 5316 to get 276.
Fetch the next digit (8) from the dividend, attach it to 276 and continue: 2768 / 720

Let's proceed to step 7:
720 goes into 2768 3 times with a remainder of 608.
Use 3 as the next digit of our solution. 
Result so far: 9273.0
Deduct 2160 from 2768 and we're left with 608.
Fetch the next digit (9) from the dividend, attach it to 608 and continue: 6089 / 720

Going ahead to step 8:
When dividing 6089 by 720, we get 8 with a remainder of 329.
Put 8 as the next digit of the answer. 
Result so far: 92738.0
Subtracting 5760 from 6089 leaves us 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.

Going ahead to step 9:
When dividing 3290 by 720, we get 4 with a remainder of 410.
The next digit of our result is 4. 
Result so far: 92738.4
If we take 2880 away from 3290, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
When dividing 4100 by 720, we get 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 92738.45
Deduct 3600 from 4100 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
If we divide 5000 by 720, we get 6 and a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 92738.456
If we subtract 4320 from 5000, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 12:
When dividing 6800 by 720, we get 9 with a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 92738.4569
Deduct 6480 from 6800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
720 goes into 3200 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 92738.45694
Subtracting 2880 from 3200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
When dividing 3200 by 720, we get 4 with a remainder of 320.
The next digit of our result is 4. 
Result so far: 92738.456944
If we take 2880 away from 3200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 92738.456944 with a balance of 3.2e-05.
