We're dividing 91618422 by 545 
The aim is to understand the frequency of 545 in 91618422.

Advancing to step 1:
The number 545 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 545

On to step 2:
When dividing 91 by 545, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 545

Moving on to step 3:
The number 545 fits into 916 1 times, leaving a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 545 from 916 to get 371.
Fetch the next digit (1) from the dividend, attach it to 371 and continue: 3711 / 545

Going ahead to step 4:
545 goes into 3711 6 times with a remainder of 441.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 441 after subtracting 3270 from 3711.
Bring next digit (8) of the dividend behind the 441 and repeat the process: 4418 / 545

On to step 5:
When dividing 4418 by 545, we get 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 4360 away from 4418, we end up with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 545

On to step 6:
545 goes into 584 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1681.0
Subtracting 545 from 584 leaves us with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 545

On to step 7:
392 divided by 545 is 0 with a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 16810.0
If we subtract 0 from 392, we get 392.
Append the next digit (2) from the dividend to 392 and continue with: 3922 / 545

Step 8:
545 can be fit into 3922 7 times, resulting in a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 168107.0
If we subtract 3815 from 3922, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 9:
The number 545 fits into 1070 1 times, leaving a remainder of 525.
Write down 1 as next digit of the result. 
Result so far: 168107.1
If we take 545 away from 1070, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 10:
The number 545 fits into 5250 9 times, leaving a remainder of 345.
The next digit of our result is 9. 
Result so far: 168107.19
Subtract 4905 from 5250 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 11:
545 can be fit into 3450 6 times, resulting in a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 168107.196
Deduct 3270 from 3450 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
The number 545 fits into 1800 3 times, leaving a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 168107.1963
Subtracting 1635 from 1800 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 13:
545 goes into 1650 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 168107.19633
The remainder is 15 after subtracting 1635 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 168107.19633 with a remainder of 1.5e-05.
