Let's divide 84420415 by 539
The aim is to understand the frequency of 539 in 84420415.

Advancing to step 1:
When dividing 8 by 539, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 539

Moving on to step 2:
539 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 539

Step 3:
539 goes into 844 1 times with a remainder of 305.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 539 from 844, we get 305.
Bring next digit (2) of the dividend behind the 305 and repeat the process: 3052 / 539

On to step 4:
When dividing 3052 by 539, we get 5 with a remainder of 357.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2695 from 3052 leaves us with 357.
Take the next digit (0) from the dividend and append it to 357, then repeat: 3570 / 539

Step 5:
539 goes into 3570 6 times with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 156.0
If we subtract 3234 from 3570, we get 336.
Grab the next digit (4) from the dividend, add it to 336, then carry on: 3364 / 539

Advancing to step 6:
If we divide 3364 by 539, we get 6 and a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 1566.0
Subtracting 3234 from 3364 leaves us with 130.
Bring next digit (1) of the dividend behind the 130 and repeat the process: 1301 / 539

On to step 7:
539 goes into 1301 2 times with a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 15662.0
The remainder is 223 after subtracting 1078 from 1301.
Grab the next digit (5) from the dividend, add it to 223, then carry on: 2235 / 539

Going ahead to step 8:
2235 divided by 539 is 4 with a remainder of 79.
The next digit of our result is 4. 
Result so far: 156624.0
If we subtract 2156 from 2235, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
The number 539 fits into 790 1 times, leaving a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 156624.1
Subtract 539 from 790 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 10:
The number 539 fits into 2510 4 times, leaving a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 156624.14
If we take 2156 away from 2510, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 11:
3540 divided by 539 is 6 with a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 156624.146
Subtracting 3234 from 3540 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 12:
539 goes into 3060 5 times with a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 156624.1465
Subtract 2695 from 3060 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 13:
539 goes into 3650 6 times with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 156624.14656
Subtracting 3234 from 3650 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 14:
When dividing 4160 by 539, we get 7 with a remainder of 387.
Put 7 as the next digit of the answer. 
Result so far: 156624.146567
If we subtract 3773 from 4160, we get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 15:
When dividing 3870 by 539, we get 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 156624.1465677
Subtract 3773 from 3870 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final result is 156624.1465677 with a remainder of 9.7e-07.
