We're dividing 553053 by 73 
The aim is to understand the frequency of 73 in 553053.

Going ahead to step 1:
5 divided by 73 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 73

Let's proceed to step 2:
55 divided by 73 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 73

Let's proceed to step 3:
If we divide 553 by 73, we get 7 and a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 511 from 553, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 73

On to step 4:
The number 73 fits into 420 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 365 from 420, we get 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 73

Step 5:
The number 73 fits into 555 7 times, leaving a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 757.0
If we take 511 away from 555, we end up with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 73

Advancing to step 6:
73 can be fit into 443 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 7576.0
Subtract 438 from 443 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
73 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7576.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 73 fits into 500 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 7576.06
Subtract 438 from 500 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
If we divide 620 by 73, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 7576.068
Deduct 584 from 620 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
The number 73 fits into 360 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 7576.0684
If we take 292 away from 360, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
680 divided by 73 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 7576.06849
If we take 657 away from 680, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
If we divide 230 by 73, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 7576.068493
If we take 219 away from 230, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
If we divide 110 by 73, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 7576.0684931
Subtracting 73 from 110 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
When dividing 370 by 73, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 7576.06849315
If we subtract 365 from 370, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 7576.06849315 with a remaining 5e-09.
