66680764 ÷ 672 
The aim is to understand the frequency of 672 in 66680764.

Moving on to step 1:
When dividing 6 by 672, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 672

Advancing to step 2:
672 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 672

Let's proceed to step 3:
The number 672 fits into 666 0 times, leaving a remainder of 666.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 666 and we're left with 666.
Fetch the next digit (8) from the dividend, attach it to 666 and continue: 6668 / 672

Step 4:
If we divide 6668 by 672, we get 9 and a remainder of 620.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 6048 from 6668, we get 620.
Fetch the next digit (0) from the dividend, attach it to 620 and continue: 6200 / 672

Moving on to step 5:
When dividing 6200 by 672, we get 9 with a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 6048 from 6200 to get 152.
Take the next digit (7) from the dividend and append it to 152, then repeat: 1527 / 672

Step 6:
If we divide 1527 by 672, we get 2 and a remainder of 183.
Use 2 as the next digit of our solution. 
Result so far: 992.0
If we take 1344 away from 1527, we end up with 183.
Bring next digit (6) of the dividend behind the 183 and repeat the process: 1836 / 672

Moving on to step 7:
672 can be fit into 1836 2 times, resulting in a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 9922.0
Subtract 1344 from 1836 to get 492.
Include the next digit (4) from the dividend after 492, then repeat: 4924 / 672

Let's proceed to step 8:
672 can be fit into 4924 7 times, resulting in a remainder of 220.
The next digit of our result is 7. 
Result so far: 99227.0
Deduct 4704 from 4924 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 9:
When dividing 2200 by 672, we get 3 with a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 99227.3
Subtract 2016 from 2200 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
1840 divided by 672 is 2 with a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 99227.32
The remainder is 496 after subtracting 1344 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 11:
672 goes into 4960 7 times with a remainder of 256.
Use 7 as the next digit of our solution. 
Result so far: 99227.327
Subtracting 4704 from 4960 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 12:
2560 divided by 672 is 3 with a remainder of 544.
Write down 3 as next digit of the result. 
Result so far: 99227.3273
The remainder is 544 after subtracting 2016 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 13:
5440 divided by 672 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 99227.32738
If we take 5376 away from 5440, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 672, we get 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 99227.32738
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
When dividing 6400 by 672, we get 9 with a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 99227.3273809
If we subtract 6048 from 6400, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
672 goes into 3520 5 times with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 99227.32738095
Deduct 3360 from 3520 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 99227.32738095 with a balance of 1.6e-07.
