306357 divided by 73 
The aim is to understand the frequency of 73 in 306357.

Going ahead to step 1:
73 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 73

On to step 2:
30 divided by 73 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 73

On to step 3:
When dividing 306 by 73, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 292 from 306 to get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 73

Advancing to step 4:
143 divided by 73 is 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 73 from 143, we get 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 73

On to step 5:
73 goes into 705 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
Subtracting 657 from 705 leaves us with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 73

Advancing to step 6:
If we divide 487 by 73, we get 6 and a remainder of 49.
The next digit of our result is 6. 
Result so far: 4196.0
The remainder is 49 after subtracting 438 from 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
The number 73 fits into 490 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 4196.6
Deduct 438 from 490 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
If we divide 520 by 73, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4196.67
Deduct 511 from 520 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 73 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 4196.671
If we subtract 73 from 90, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
If we divide 170 by 73, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4196.6712
If we take 146 away from 170, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
If we divide 240 by 73, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 4196.67123
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
73 goes into 210 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 4196.671232
If we take 146 away from 210, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 73, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 4196.6712328
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
If we divide 560 by 73, we get 7 and a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 4196.67123287
Deduct 511 from 560 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 4196.67123287 and a remainder of 4.9e-08.
