We look at the division of 66444334 by 907 
The aim is to understand the frequency of 907 in 66444334.

Step 1:
When dividing 6 by 907, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 907

Advancing to step 2:
When dividing 66 by 907, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 907

Moving on to step 3:
The number 907 fits into 664 0 times, leaving a remainder of 664.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 664 and we're left with 664.
Grab the next digit (4) from the dividend, add it to 664, then carry on: 6644 / 907

Moving on to step 4:
If we divide 6644 by 907, we get 7 and a remainder of 295.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6349 away from 6644, we end up with 295.
Take the next digit (4) from the dividend and append it to 295, then repeat: 2954 / 907

Going ahead to step 5:
907 can be fit into 2954 3 times, resulting in a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 2721 from 2954, we get 233.
Append the next digit (3) from the dividend to 233 and continue with: 2333 / 907

Let's proceed to step 6:
2333 divided by 907 is 2 with a remainder of 519.
The next digit of our result is 2. 
Result so far: 732.0
If we subtract 1814 from 2333, we get 519.
Take the next digit (3) from the dividend and append it to 519, then repeat: 5193 / 907

Let's proceed to step 7:
907 can be fit into 5193 5 times, resulting in a remainder of 658.
Use 5 as the next digit of our solution. 
Result so far: 7325.0
The remainder is 658 after subtracting 4535 from 5193.
Take the next digit (4) from the dividend and append it to 658, then repeat: 6584 / 907

Advancing to step 8:
If we divide 6584 by 907, we get 7 and a remainder of 235.
Put 7 as the next digit of the answer. 
Result so far: 73257.0
Subtracting 6349 from 6584 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
907 goes into 2350 2 times with a remainder of 536.
The next digit of our result is 2. 
Result so far: 73257.2
Deduct 1814 from 2350 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 10:
907 can be fit into 5360 5 times, resulting in a remainder of 825.
Put 5 as the next digit of the answer. 
Result so far: 73257.25
If we take 4535 away from 5360, we end up with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Let's proceed to step 11:
907 goes into 8250 9 times with a remainder of 87.
The next digit of our result is 9. 
Result so far: 73257.259
Subtracting 8163 from 8250 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 12:
907 goes into 870 0 times with a remainder of 870.
The number 0 becomes the next digit in our result. 
Result so far: 73257.259
Subtract 0 from 870 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Step 13:
When dividing 8700 by 907, we get 9 with a remainder of 537.
Put 9 as the next digit of the answer. 
Result so far: 73257.25909
Subtract 8163 from 8700 to get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 14:
5370 divided by 907 is 5 with a remainder of 835.
The next digit of our result is 5. 
Result so far: 73257.259095
Subtracting 4535 from 5370 leaves us with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

On to step 15:
907 goes into 8350 9 times with a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 73257.2590959
Subtract 8163 from 8350 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 16:
907 goes into 1870 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 73257.25909592
Subtract 1814 from 1870 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 73257.25909592 with a remaining 5.6e-08.
