We divide 644247 by 73
The aim is to understand the frequency of 73 in 644247.

Let's proceed to step 1:
73 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 73

Moving on to step 2:
73 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 73

Moving on to step 3:
73 can be fit into 644 8 times, resulting in a remainder of 60.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 584 from 644 leaves us with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 73

Going ahead to step 4:
73 goes into 602 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 584 from 602 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 73

Let's proceed to step 5:
The number 73 fits into 184 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 882.0
Deduct 146 from 184 and we're left with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 73

Advancing to step 6:
73 can be fit into 387 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 8825.0
Subtract 365 from 387 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
The number 73 fits into 220 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 8825.3
Subtract 219 from 220 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
73 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8825.3
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.

Let's proceed to step 9:
If we divide 100 by 73, we get 1 and a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 8825.301
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 10:
73 can be fit into 270 3 times, resulting in a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 8825.3013
Deduct 219 from 270 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
If we divide 510 by 73, we get 6 and a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 8825.30136
Subtracting 438 from 510 leaves us 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.

Let's proceed to step 12:
The number 73 fits into 720 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 8825.301369
Subtract 657 from 720 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 13:
73 can be fit into 630 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8825.3013698
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.

On to step 14:
73 can be fit into 460 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 8825.30136986
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.

The quotient of the division is 8825.30136986, and the remainder is 2.2e-08.
