We look at the division of 84545824 by 907 
The aim is to understand the frequency of 907 in 84545824.

Let's proceed to step 1:
907 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 907

Let's proceed to step 2:
907 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 907

Let's proceed to step 3:
907 can be fit into 845 0 times, resulting in a remainder of 845.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 845, we end up with 845.
Take the next digit (4) from the dividend and append it to 845, then repeat: 8454 / 907

On to step 4:
907 goes into 8454 9 times with a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 291 after subtracting 8163 from 8454.
Include the next digit (5) from the dividend after 291, then repeat: 2915 / 907

Advancing to step 5:
When dividing 2915 by 907, we get 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 2721 away from 2915, we end up with 194.
Include the next digit (8) from the dividend after 194, then repeat: 1948 / 907

Moving on to step 6:
When dividing 1948 by 907, we get 2 with a remainder of 134.
The next digit of our result is 2. 
Result so far: 932.0
If we subtract 1814 from 1948, we get 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 907

Let's proceed to step 7:
If we divide 1342 by 907, we get 1 and a remainder of 435.
The number 1 becomes the next digit in our result. 
Result so far: 9321.0
Deduct 907 from 1342 and we're left with 435.
Grab the next digit (4) from the dividend, add it to 435, then carry on: 4354 / 907

Let's proceed to step 8:
4354 divided by 907 is 4 with a remainder of 726.
The next digit of our result is 4. 
Result so far: 93214.0
Subtracting 3628 from 4354 leaves us with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Step 9:
907 goes into 7260 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 93214.8
Deduct 7256 from 7260 and we're left 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 10:
If we divide 40 by 907, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 93214.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
907 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 93214.8
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 93214.8 with a remainder of 0.04.
