90473318 ÷ 73 
The aim is to understand the frequency of 73 in 90473318.

Let's proceed to step 1:
9 divided by 73 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 73

Moving on to step 2:
90 divided by 73 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 73 from 90 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 73

Step 3:
When dividing 174 by 73, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 146 from 174, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 73

Moving on to step 4:
73 can be fit into 287 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 123.0
The remainder is 68 after subtracting 219 from 287.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 73

On to step 5:
683 divided by 73 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1239.0
If we take 657 away from 683, we end up with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 73

Advancing to step 6:
73 goes into 263 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 12393.0
If we take 219 away from 263, we end up with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 73

On to step 7:
If we divide 441 by 73, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 123936.0
If we take 438 away from 441, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 73

Advancing to step 8:
73 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 1239360.0
Subtracting 0 from 38 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 73 fits into 380 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1239360.5
Deduct 365 from 380 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 73 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1239360.52
Subtracting 146 from 150 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 73 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1239360.52
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
400 divided by 73 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1239360.5205
Subtracting 365 from 400 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
The number 73 fits into 350 4 times, leaving a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 1239360.52054
Subtracting 292 from 350 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
When dividing 580 by 73, we get 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 1239360.520547
Subtracting 511 from 580 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 15:
The number 73 fits into 690 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 1239360.5205479
If we take 657 away from 690, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 16:
If we divide 330 by 73, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 1239360.52054794
If we subtract 292 from 330, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 1239360.52054794 with a balance of 3.8e-08.
