We look at the division of 6705705 by 520 
The aim is to understand the frequency of 520 in 6705705.

Let's proceed to step 1:
520 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 520

Moving on to step 2:
When dividing 67 by 520, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 520

Let's proceed to step 3:
520 can be fit into 670 1 times, resulting in a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 150 after subtracting 520 from 670.
Grab the next digit (5) from the dividend, add it to 150, then carry on: 1505 / 520

On to step 4:
520 goes into 1505 2 times with a remainder of 465.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1040 from 1505, we get 465.
Append the next digit (7) from the dividend to 465 and continue with: 4657 / 520

Let's proceed to step 5:
520 goes into 4657 8 times with a remainder of 497.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 4160 from 4657 to get 497.
Bring next digit (0) of the dividend behind the 497 and repeat the process: 4970 / 520

Going ahead to step 6:
When dividing 4970 by 520, we get 9 with a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 1289.0
Subtract 4680 from 4970 to get 290.
Fetch the next digit (5) from the dividend, attach it to 290 and continue: 2905 / 520

Let's proceed to step 7:
520 goes into 2905 5 times with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 12895.0
Subtracting 2600 from 2905 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 8:
520 can be fit into 3050 5 times, resulting in a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 12895.5
Subtracting 2600 from 3050 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 9:
520 goes into 4500 8 times with a remainder of 340.
The next digit of our result is 8. 
Result so far: 12895.58
Subtracting 4160 from 4500 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
The number 520 fits into 3400 6 times, leaving a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 12895.586
Subtract 3120 from 3400 to 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.

Advancing to step 11:
520 can be fit into 2800 5 times, resulting in a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 12895.5865
If we take 2600 away from 2800, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
520 can be fit into 2000 3 times, resulting in a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 12895.58653
If we take 1560 away from 2000, we end up 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.

Let's proceed to step 13:
520 goes into 4400 8 times with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 12895.586538
If we take 4160 away from 4400, we end up 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.

Step 14:
520 goes into 2400 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 12895.5865384
The remainder is 320 after subtracting 2080 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
520 can be fit into 3200 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 12895.58653846
Subtract 3120 from 3200 to 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.

Our division results in 12895.58653846 with a remaining 8e-08.
