Let's divide 60066768 by 520
The aim is to understand the frequency of 520 in 60066768.

Step 1:
520 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 520

Let's proceed to step 2:
60 divided by 520 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 520

Going ahead to step 3:
520 goes into 600 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 520 from 600 leaves us with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 520

Step 4:
806 divided by 520 is 1 with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 520 from 806 to get 286.
Bring next digit (6) of the dividend behind the 286 and repeat the process: 2866 / 520

Moving on to step 5:
If we divide 2866 by 520, we get 5 and a remainder of 266.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 266 after subtracting 2600 from 2866.
Append the next digit (7) from the dividend to 266 and continue with: 2667 / 520

Advancing to step 6:
When dividing 2667 by 520, we get 5 with a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 1155.0
If we take 2600 away from 2667, we end up with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 520

Moving on to step 7:
676 divided by 520 is 1 with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 11551.0
Deduct 520 from 676 and we're left with 156.
Append the next digit (8) from the dividend to 156 and continue with: 1568 / 520

On to step 8:
The number 520 fits into 1568 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 115513.0
Deduct 1560 from 1568 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 520 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 115513.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 520, we get 1 and a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 115513.01
If we subtract 520 from 800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 115513.015
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
If we divide 2000 by 520, we get 3 and a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 115513.0153
Deduct 1560 from 2000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 13:
The number 520 fits into 4400 8 times, leaving a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 115513.01538
Subtracting 4160 from 4400 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.

Let's proceed to step 14:
2400 divided by 520 is 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 115513.015384
Subtract 2080 from 2400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
The number 520 fits into 3200 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 115513.0153846
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
When dividing 800 by 520, we get 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 115513.01538461
The remainder is 280 after subtracting 520 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 115513.01538461 with a remainder of 2.8e-07.
