684856 ÷ 73 
The aim is to understand the frequency of 73 in 684856.

Step 1:
6 divided by 73 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 73

Let's proceed to step 2:
The number 73 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 73

Advancing to step 3:
684 divided by 73 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 657 from 684 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 73

Moving on to step 4:
278 divided by 73 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 219 from 278 and we're left with 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 73

Advancing to step 5:
73 can be fit into 595 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 938.0
Subtracting 584 from 595 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 73

Advancing to step 6:
If we divide 116 by 73, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 9381.0
If we take 73 away from 116, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
430 divided by 73 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 9381.5
If we take 365 away from 430, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
650 divided by 73 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 9381.58
Subtracting 584 from 650 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
When dividing 660 by 73, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9381.589
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 73 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 9381.589
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
73 can be fit into 300 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9381.58904
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 73 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 9381.589041
If we take 73 away from 80, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
73 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 9381.589041
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
73 goes into 700 9 times with a remainder of 43.
The next digit of our result is 9. 
Result so far: 9381.58904109
If we take 657 away from 700, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 9381.58904109, with a leftover of 4.3e-08.
