We look at the division of 63156160 by 520 
The aim is to understand the frequency of 520 in 63156160.

Moving on to step 1:
520 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 520

Going ahead to step 2:
63 divided by 520 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 520

Going ahead to step 3:
520 goes into 631 1 times with a remainder of 111.
The next digit of our result is 1. 
Result so far: 1.0
If we take 520 away from 631, we end up with 111.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 520

Going ahead to step 4:
If we divide 1115 by 520, we get 2 and a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 75 after subtracting 1040 from 1115.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 520

Let's proceed to step 5:
The number 520 fits into 756 1 times, leaving a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 520 from 756 to get 236.
Append the next digit (1) from the dividend to 236 and continue with: 2361 / 520

Moving on to step 6:
If we divide 2361 by 520, we get 4 and a remainder of 281.
The number 4 becomes the next digit in our result. 
Result so far: 1214.0
If we subtract 2080 from 2361, we get 281.
Include the next digit (6) from the dividend after 281, then repeat: 2816 / 520

On to step 7:
The number 520 fits into 2816 5 times, leaving a remainder of 216.
The next digit of our result is 5. 
Result so far: 12145.0
Subtracting 2600 from 2816 leaves us with 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 520

On to step 8:
520 goes into 2160 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 121454.0
If we take 2080 away from 2160, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 520, we get 1 with a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 121454.1
If we take 520 away from 800, we end up with 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 10:
If we divide 2800 by 520, we get 5 and a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 121454.15
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 11:
2000 divided by 520 is 3 with a remainder of 440.
Put 3 as the next digit of the answer. 
Result so far: 121454.153
If we subtract 1560 from 2000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
The number 520 fits into 4400 8 times, leaving a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 121454.1538
If we subtract 4160 from 4400, we get 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 13:
If we divide 2400 by 520, we get 4 and a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 121454.15384
Deduct 2080 from 2400 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
3200 divided by 520 is 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 121454.153846
If we take 3120 away from 3200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
520 goes into 800 1 times with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 121454.1538461
Subtract 520 from 800 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.

Moving on to step 16:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
The next digit of our result is 5. 
Result so far: 121454.15384615
Deduct 2600 from 2800 and we're left 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.

In conclusion, the division gives 121454.15384615 with a balance of 2e-07.
