We look at the division of 87523314 by 948 
The aim is to understand the frequency of 948 in 87523314.

Moving on to step 1:
948 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 948

Moving on to step 2:
If we divide 87 by 948, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 948

Going ahead to step 3:
948 can be fit into 875 0 times, resulting in a remainder of 875.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 875 to get 875.
Append the next digit (2) from the dividend to 875 and continue with: 8752 / 948

Step 4:
If we divide 8752 by 948, we get 9 and a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8532 from 8752 and we're left with 220.
Append the next digit (3) from the dividend to 220 and continue with: 2203 / 948

Advancing to step 5:
When dividing 2203 by 948, we get 2 with a remainder of 307.
Write down 2 as next digit of the result. 
Result so far: 92.0
The remainder is 307 after subtracting 1896 from 2203.
Include the next digit (3) from the dividend after 307, then repeat: 3073 / 948

Let's proceed to step 6:
948 can be fit into 3073 3 times, resulting in a remainder of 229.
The number 3 becomes the next digit in our result. 
Result so far: 923.0
The remainder is 229 after subtracting 2844 from 3073.
Fetch the next digit (1) from the dividend, attach it to 229 and continue: 2291 / 948

Going ahead to step 7:
2291 divided by 948 is 2 with a remainder of 395.
Use 2 as the next digit of our solution. 
Result so far: 9232.0
The remainder is 395 after subtracting 1896 from 2291.
Bring next digit (4) of the dividend behind the 395 and repeat the process: 3954 / 948

Step 8:
948 goes into 3954 4 times with a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 92324.0
Subtracting 3792 from 3954 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
1620 divided by 948 is 1 with a remainder of 672.
Write down 1 as next digit of the result. 
Result so far: 92324.1
The remainder is 672 after subtracting 948 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 10:
When dividing 6720 by 948, we get 7 with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 92324.17
The remainder is 84 after subtracting 6636 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
The number 948 fits into 840 0 times, leaving a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 92324.17
Subtracting 0 from 840 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 12:
The number 948 fits into 8400 8 times, leaving a remainder of 816.
The next digit of our result is 8. 
Result so far: 92324.1708
If we subtract 7584 from 8400, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Advancing to step 13:
If we divide 8160 by 948, we get 8 and a remainder of 576.
The next digit of our result is 8. 
Result so far: 92324.17088
Deduct 7584 from 8160 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 92324.17088 with a remainder of 0.000576.
