147781 divided by 73 
The aim is to understand the frequency of 73 in 147781.

On to step 1:
1 divided by 73 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 73

Moving on to step 2:
73 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 73

Advancing to step 3:
When dividing 147 by 73, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 146 from 147 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 73

On to step 4:
17 divided by 73 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 73

Let's proceed to step 5:
73 can be fit into 178 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Deduct 146 from 178 and we're left with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 73

On to step 6:
If we divide 321 by 73, we get 4 and a remainder of 29.
The next digit of our result is 4. 
Result so far: 2024.0
Subtract 292 from 321 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
290 divided by 73 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 2024.3
Subtracting 219 from 290 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 8:
710 divided by 73 is 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 2024.39
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
73 goes into 530 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 2024.397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
The number 73 fits into 190 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 2024.3972
If we subtract 146 from 190, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
73 can be fit into 440 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2024.39726
If we take 438 away from 440, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
73 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2024.39726
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
73 goes into 200 2 times with a remainder of 54.
The next digit of our result is 2. 
Result so far: 2024.3972602
The remainder is 54 after subtracting 146 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
The number 73 fits into 540 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 2024.39726027
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 2024.39726027, with a leftover of 2.9e-08.
