Let's divide 65372553 by 523
The aim is to understand the frequency of 523 in 65372553.

Advancing to step 1:
If we divide 6 by 523, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 523

Step 2:
523 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 523

Moving on to step 3:
When dividing 653 by 523, we get 1 with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 130 after subtracting 523 from 653.
Grab the next digit (7) from the dividend, add it to 130, then carry on: 1307 / 523

Advancing to step 4:
523 goes into 1307 2 times with a remainder of 261.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1046 from 1307 to get 261.
Append the next digit (2) from the dividend to 261 and continue with: 2612 / 523

Let's proceed to step 5:
The number 523 fits into 2612 4 times, leaving a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 2092 from 2612 to get 520.
Include the next digit (5) from the dividend after 520, then repeat: 5205 / 523

Step 6:
5205 divided by 523 is 9 with a remainder of 498.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
Deduct 4707 from 5205 and we're left with 498.
Include the next digit (5) from the dividend after 498, then repeat: 4985 / 523

Step 7:
523 can be fit into 4985 9 times, resulting in a remainder of 278.
The next digit of our result is 9. 
Result so far: 12499.0
Deduct 4707 from 4985 and we're left with 278.
Grab the next digit (3) from the dividend, add it to 278, then carry on: 2783 / 523

Moving on to step 8:
When dividing 2783 by 523, we get 5 with a remainder of 168.
The number 5 becomes the next digit in our result. 
Result so far: 124995.0
Subtracting 2615 from 2783 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
The number 523 fits into 1680 3 times, leaving a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 124995.3
Subtract 1569 from 1680 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 10:
1110 divided by 523 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 124995.32
Deduct 1046 from 1110 and we're left 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.

Moving on to step 11:
The number 523 fits into 640 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 124995.321
The remainder is 117 after subtracting 523 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 12:
1170 divided by 523 is 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 124995.3212
The remainder is 124 after subtracting 1046 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 13:
1240 divided by 523 is 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 124995.32122
Deduct 1046 from 1240 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final result is 124995.32122 with a remainder of 0.000194.
