We look at the division of 65671288 by 524 
The aim is to understand the frequency of 524 in 65671288.

Advancing to step 1:
The number 524 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 524

Let's proceed to step 2:
If we divide 65 by 524, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 524

Moving on to step 3:
When dividing 656 by 524, we get 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 524 from 656 and we're left with 132.
Include the next digit (7) from the dividend after 132, then repeat: 1327 / 524

On to step 4:
1327 divided by 524 is 2 with a remainder of 279.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1048 from 1327 and we're left with 279.
Bring next digit (1) of the dividend behind the 279 and repeat the process: 2791 / 524

Advancing to step 5:
2791 divided by 524 is 5 with a remainder of 171.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 2620 from 2791 to get 171.
Append the next digit (2) from the dividend to 171 and continue with: 1712 / 524

Let's proceed to step 6:
If we divide 1712 by 524, we get 3 and a remainder of 140.
The next digit of our result is 3. 
Result so far: 1253.0
The remainder is 140 after subtracting 1572 from 1712.
Grab the next digit (8) from the dividend, add it to 140, then carry on: 1408 / 524

On to step 7:
When dividing 1408 by 524, we get 2 with a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 12532.0
If we subtract 1048 from 1408, we get 360.
Grab the next digit (8) from the dividend, add it to 360, then carry on: 3608 / 524

Advancing to step 8:
When dividing 3608 by 524, we get 6 with a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 125326.0
If we subtract 3144 from 3608, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 9:
524 goes into 4640 8 times with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 125326.8
If we subtract 4192 from 4640, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 10:
When dividing 4480 by 524, we get 8 with a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 125326.88
If we take 4192 away from 4480, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 125326.88 with a remainder of 0.288.
