80724077 divided by 73 
The aim is to understand the frequency of 73 in 80724077.

Moving on to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 73

Going ahead to step 2:
73 goes into 80 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 73 from 80 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 73

Going ahead to step 3:
The number 73 fits into 77 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 73 from 77 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 73

Moving on to step 4:
When dividing 42 by 73, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 73

On to step 5:
73 goes into 424 5 times with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 1105.0
Deduct 365 from 424 and we're left with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 73

Going ahead to step 6:
73 can be fit into 590 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 11058.0
If we take 584 away from 590, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 73

Going ahead to step 7:
73 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 110580.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 73

Going ahead to step 8:
When dividing 677 by 73, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 1105809.0
If we subtract 657 from 677, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 73, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 1105809.2
Deduct 146 from 200 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
When dividing 540 by 73, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1105809.27
If we subtract 511 from 540, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
73 can be fit into 290 3 times, resulting in a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 1105809.273
If we subtract 219 from 290, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
73 goes into 710 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 1105809.2739
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
530 divided by 73 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1105809.27397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
73 goes into 190 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1105809.273972
If we subtract 146 from 190, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 15:
73 can be fit into 440 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 1105809.2739726
The remainder is 2 after subtracting 438 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
The number 73 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1105809.2739726
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1105809.2739726, and the remainder is 2e-08.
