1405627 divided by 520 
The aim is to understand the frequency of 520 in 1405627.

Advancing to step 1:
The number 520 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 520

Let's proceed to step 2:
The number 520 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 520

On to step 3:
140 divided by 520 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 140 after subtracting 0 from 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 520

Advancing to step 4:
When dividing 1405 by 520, we get 2 with a remainder of 365.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1040 from 1405, we get 365.
Take the next digit (6) from the dividend and append it to 365, then repeat: 3656 / 520

Let's proceed to step 5:
If we divide 3656 by 520, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 3640 from 3656 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 520

Step 6:
520 can be fit into 162 0 times, resulting in a remainder of 162.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
The remainder is 162 after subtracting 0 from 162.
Fetch the next digit (7) from the dividend, attach it to 162 and continue: 1627 / 520

Moving on to step 7:
520 goes into 1627 3 times with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 2703.0
Deduct 1560 from 1627 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 8:
670 divided by 520 is 1 with a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 2703.1
The remainder is 150 after subtracting 520 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
When dividing 1500 by 520, we get 2 with a remainder of 460.
The number 2 becomes the next digit in our result. 
Result so far: 2703.12
If we take 1040 away from 1500, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
When dividing 4600 by 520, we get 8 with a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 2703.128
Deduct 4160 from 4600 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.

Step 11:
4400 divided by 520 is 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 2703.1288
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.

Our division results in 2703.1288 with a remaining 0.0024.
