851012 divided by 73 
The aim is to understand the frequency of 73 in 851012.

Advancing to step 1:
73 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 73

Going ahead to step 2:
The number 73 fits into 85 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 73 from 85 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 73

Going ahead to step 3:
When dividing 121 by 73, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 73 from 121 leaves us with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 73

On to step 4:
If we divide 480 by 73, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 438 from 480 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 73

Step 5:
When dividing 421 by 73, we get 5 with a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
If we subtract 365 from 421, we get 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 73

Step 6:
73 goes into 562 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 11657.0
The remainder is 51 after subtracting 511 from 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
510 divided by 73 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 11657.6
If we take 438 away from 510, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
73 can be fit into 720 9 times, resulting in a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 11657.69
The remainder is 63 after subtracting 657 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
73 goes into 630 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 11657.698
Deduct 584 from 630 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
73 can be fit into 460 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 11657.6986
Subtracting 438 from 460 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
73 can be fit into 220 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 11657.69863
Subtracting 219 from 220 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
When dividing 10 by 73, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11657.69863
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
73 can be fit into 100 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 11657.6986301
If we take 73 away from 100, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
270 divided by 73 is 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 11657.69863013
The remainder is 51 after subtracting 219 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 11657.69863013, and the remainder is 5.1e-08.
