We look at the division of 55273521 by 545 
The aim is to understand the frequency of 545 in 55273521.

Going ahead to step 1:
545 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 545

Moving on to step 2:
545 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 545

On to step 3:
552 divided by 545 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 545 from 552 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 545

Let's proceed to step 4:
If we divide 77 by 545, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 545

Step 5:
773 divided by 545 is 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we subtract 545 from 773, we get 228.
Include the next digit (5) from the dividend after 228, then repeat: 2285 / 545

Step 6:
The number 545 fits into 2285 4 times, leaving a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 1014.0
If we take 2180 away from 2285, we end up with 105.
Grab the next digit (2) from the dividend, add it to 105, then carry on: 1052 / 545

On to step 7:
If we divide 1052 by 545, we get 1 and a remainder of 507.
Use 1 as the next digit of our solution. 
Result so far: 10141.0
If we take 545 away from 1052, we end up with 507.
Fetch the next digit (1) from the dividend, attach it to 507 and continue: 5071 / 545

Moving on to step 8:
545 goes into 5071 9 times with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 101419.0
Deduct 4905 from 5071 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
When dividing 1660 by 545, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 101419.3
Subtracting 1635 from 1660 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 545 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 101419.3
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
545 goes into 2500 4 times with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 101419.304
The remainder is 320 after subtracting 2180 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
3200 divided by 545 is 5 with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 101419.3045
Deduct 2725 from 3200 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 13:
The number 545 fits into 4750 8 times, leaving a remainder of 390.
The number 8 becomes the next digit in our result. 
Result so far: 101419.30458
Subtracting 4360 from 4750 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 14:
If we divide 3900 by 545, we get 7 and a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 101419.304587
Deduct 3815 from 3900 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
The number 545 fits into 850 1 times, leaving a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 101419.3045871
If we subtract 545 from 850, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 16:
If we divide 3050 by 545, we get 5 and a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 101419.30458715
The remainder is 325 after subtracting 2725 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 101419.30458715 and a remainder of 3.25e-07.
