We look at the division of 73534333 by 523 
The aim is to understand the frequency of 523 in 73534333.

On to step 1:
When dividing 7 by 523, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 523

Advancing to step 2:
523 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 523

Let's proceed to step 3:
523 goes into 735 1 times with a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 523 from 735 to get 212.
Take the next digit (3) from the dividend and append it to 212, then repeat: 2123 / 523

Step 4:
If we divide 2123 by 523, we get 4 and a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2092 from 2123 leaves us with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 523

Let's proceed to step 5:
314 divided by 523 is 0 with a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 140.0
If we subtract 0 from 314, we get 314.
Take the next digit (3) from the dividend and append it to 314, then repeat: 3143 / 523

Moving on to step 6:
523 can be fit into 3143 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 1406.0
Subtracting 3138 from 3143 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 523

Moving on to step 7:
523 can be fit into 53 0 times, resulting in a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 14060.0
If we subtract 0 from 53, we get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 523

On to step 8:
523 goes into 533 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 140601.0
If we subtract 523 from 533, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 523 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 140601.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
1000 divided by 523 is 1 with a remainder of 477.
Use 1 as the next digit of our solution. 
Result so far: 140601.01
If we take 523 away from 1000, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 11:
4770 divided by 523 is 9 with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 140601.019
Subtract 4707 from 4770 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
630 divided by 523 is 1 with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 140601.0191
The remainder is 107 after subtracting 523 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 13:
523 goes into 1070 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 140601.01912
Subtract 1046 from 1070 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
523 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 140601.01912
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
The number 523 fits into 2400 4 times, leaving a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 140601.0191204
If we subtract 2092 from 2400, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 16:
523 goes into 3080 5 times with a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 140601.01912045
Deduct 2615 from 3080 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Our division results in 140601.01912045 with a remaining 4.65e-07.
