563451 ÷ 73 
The aim is to understand the frequency of 73 in 563451.

Advancing to step 1:
5 divided by 73 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 73

Let's proceed to step 2:
The number 73 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 73

Advancing to step 3:
73 goes into 563 7 times with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 511 from 563 to get 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 73

Let's proceed to step 4:
If we divide 524 by 73, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 77.0
Deduct 511 from 524 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 73

On to step 5:
135 divided by 73 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 771.0
If we subtract 73 from 135, we get 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 73

Step 6:
The number 73 fits into 621 8 times, leaving a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 7718.0
Subtracting 584 from 621 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.

On to step 7:
73 goes into 370 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7718.5
Subtract 365 from 370 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.

On to step 8:
50 divided by 73 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7718.5
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.

On to step 9:
73 can be fit into 500 6 times, resulting in a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 7718.506
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.

On to step 10:
620 divided by 73 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 7718.5068
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.

On to step 11:
73 goes into 360 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7718.50684
Subtract 292 from 360 to get 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 12:
When dividing 680 by 73, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7718.506849
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.

Step 13:
73 goes into 230 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 7718.5068493
Subtracting 219 from 230 leaves us 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.

Step 14:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 7718.50684931
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.

After the division, we end up with 7718.50684931 and a remainder of 3.7e-08.
