Let's divide 69139213 by 520
The aim is to understand the frequency of 520 in 69139213.

On to step 1:
520 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 520

Step 2:
69 divided by 520 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 520

On to step 3:
520 goes into 691 1 times with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 520 from 691 to get 171.
Take the next digit (3) from the dividend and append it to 171, then repeat: 1713 / 520

Moving on to step 4:
The number 520 fits into 1713 3 times, leaving a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1560 from 1713 to get 153.
Take the next digit (9) from the dividend and append it to 153, then repeat: 1539 / 520

Advancing to step 5:
520 can be fit into 1539 2 times, resulting in a remainder of 499.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Deduct 1040 from 1539 and we're left with 499.
Append the next digit (2) from the dividend to 499 and continue with: 4992 / 520

On to step 6:
If we divide 4992 by 520, we get 9 and a remainder of 312.
The number 9 becomes the next digit in our result. 
Result so far: 1329.0
If we take 4680 away from 4992, we end up with 312.
Fetch the next digit (1) from the dividend, attach it to 312 and continue: 3121 / 520

Step 7:
When dividing 3121 by 520, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 13296.0
If we subtract 3120 from 3121, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 520

Moving on to step 8:
When dividing 13 by 520, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 132960.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 520 is 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 132960.0
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
1300 divided by 520 is 2 with a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 132960.02
Deduct 1040 from 1300 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
2600 divided by 520 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 132960.025
Subtract 2600 from 2600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
If we divide 0 by 520, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 132960.025
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
The number 520 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 132960.025
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 132960.025 with a balance of 0.0.
