56921763 ÷ 73 
The aim is to understand the frequency of 73 in 56921763.

On to step 1:
73 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 73

Step 2:
56 divided by 73 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 73

Moving on to step 3:
569 divided by 73 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 511 from 569 leaves us with 58.
Include the next digit (2) from the dividend after 58, then repeat: 582 / 73

Moving on to step 4:
73 can be fit into 582 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 511 from 582 leaves us with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 73

On to step 5:
If we divide 711 by 73, we get 9 and a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 779.0
Deduct 657 from 711 and we're left with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 73

Step 6:
When dividing 547 by 73, we get 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7797.0
Deduct 511 from 547 and we're left with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 73

On to step 7:
366 divided by 73 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 77975.0
Deduct 365 from 366 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 73

Going ahead to step 8:
73 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 779750.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
When dividing 130 by 73, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 779750.1
Subtracting 73 from 130 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
When dividing 570 by 73, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 779750.17
Subtracting 511 from 570 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
590 divided by 73 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 779750.178
Deduct 584 from 590 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
73 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 779750.178
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
73 goes into 600 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 779750.17808
Subtract 584 from 600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
73 goes into 160 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 779750.178082
If we take 146 away from 160, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
73 goes into 140 1 times with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 779750.1780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 16:
If we divide 670 by 73, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 779750.17808219
Subtracting 657 from 670 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 779750.17808219 with a remainder of 1.3e-08.
