We're dividing 71136549 by 545 
The aim is to understand the frequency of 545 in 71136549.

Advancing to step 1:
7 divided by 545 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 545

On to step 2:
If we divide 71 by 545, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 545

Moving on to step 3:
545 can be fit into 711 1 times, resulting in a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 545 from 711 and we're left with 166.
Append the next digit (3) from the dividend to 166 and continue with: 1663 / 545

Going ahead to step 4:
545 goes into 1663 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 28 after subtracting 1635 from 1663.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 545

Moving on to step 5:
286 divided by 545 is 0 with a remainder of 286.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 286 leaves us with 286.
Include the next digit (5) from the dividend after 286, then repeat: 2865 / 545

On to step 6:
The number 545 fits into 2865 5 times, leaving a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 1305.0
Subtract 2725 from 2865 to get 140.
Grab the next digit (4) from the dividend, add it to 140, then carry on: 1404 / 545

Advancing to step 7:
When dividing 1404 by 545, we get 2 with a remainder of 314.
Record the quotient 2 as the next digit in the result. 
Result so far: 13052.0
If we take 1090 away from 1404, we end up with 314.
Append the next digit (9) from the dividend to 314 and continue with: 3149 / 545

Let's proceed to step 8:
545 can be fit into 3149 5 times, resulting in a remainder of 424.
Record the quotient 5 as the next digit in the result. 
Result so far: 130525.0
If we take 2725 away from 3149, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
The number 545 fits into 4240 7 times, leaving a remainder of 425.
Write down 7 as next digit of the result. 
Result so far: 130525.7
If we subtract 3815 from 4240, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 10:
545 goes into 4250 7 times with a remainder of 435.
Write down 7 as next digit of the result. 
Result so far: 130525.77
Subtracting 3815 from 4250 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

After the division, we end up with 130525.77 and a remainder of 0.435.
