868743 ÷ 73 
The aim is to understand the frequency of 73 in 868743.

Going ahead to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 73

Advancing to step 2:
73 goes into 86 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 13 after subtracting 73 from 86.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 73

Step 3:
73 can be fit into 138 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 73 from 138 leaves us with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 73

Advancing to step 4:
When dividing 657 by 73, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 657 from 657, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 73

On to step 5:
If we divide 4 by 73, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 73

Let's proceed to step 6:
The number 73 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 11900.0
Deduct 0 from 43 and we're left 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.

Step 7:
73 can be fit into 430 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 11900.5
Subtract 365 from 430 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
73 can be fit into 650 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 11900.58
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:
73 goes into 660 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 11900.589
Subtract 657 from 660 to 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.

Let's proceed to step 10:
73 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 11900.589
Subtracting 0 from 30 leaves us 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.

Let's proceed to step 11:
73 can be fit into 300 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 11900.58904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 73, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 11900.589041
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.

Advancing to step 13:
The number 73 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 11900.589041
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.

On to step 14:
The number 73 fits into 700 9 times, leaving a remainder of 43.
The next digit of our result is 9. 
Result so far: 11900.58904109
Subtracting 657 from 700 leaves us 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 quotient of the division is 11900.58904109, and the remainder is 4.3e-08.
