Let's divide 79271745 by 539
The aim is to understand the frequency of 539 in 79271745.

Going ahead to step 1:
539 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 539

Advancing to step 2:
539 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 539

Advancing to step 3:
If we divide 792 by 539, we get 1 and a remainder of 253.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 539 from 792, we get 253.
Take the next digit (7) from the dividend and append it to 253, then repeat: 2537 / 539

On to step 4:
The number 539 fits into 2537 4 times, leaving a remainder of 381.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2156 from 2537 leaves us with 381.
Fetch the next digit (1) from the dividend, attach it to 381 and continue: 3811 / 539

Advancing to step 5:
The number 539 fits into 3811 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
The remainder is 38 after subtracting 3773 from 3811.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 539

On to step 6:
If we divide 387 by 539, we get 0 and a remainder of 387.
Put 0 as the next digit of the answer. 
Result so far: 1470.0
Deduct 0 from 387 and we're left with 387.
Take the next digit (4) from the dividend and append it to 387, then repeat: 3874 / 539

Let's proceed to step 7:
If we divide 3874 by 539, we get 7 and a remainder of 101.
Record the quotient 7 as the next digit in the result. 
Result so far: 14707.0
Deduct 3773 from 3874 and we're left with 101.
Append the next digit (5) from the dividend to 101 and continue with: 1015 / 539

Going ahead to step 8:
539 goes into 1015 1 times with a remainder of 476.
The next digit of our result is 1. 
Result so far: 147071.0
Deduct 539 from 1015 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 9:
539 goes into 4760 8 times with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 147071.8
If we take 4312 away from 4760, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 10:
When dividing 4480 by 539, we get 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 147071.88
If we subtract 4312 from 4480, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 147071.88 and a remainder of 0.168.
