977488 ÷ 73 
The aim is to understand the frequency of 73 in 977488.

Let's proceed to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 73

Step 2:
When dividing 97 by 73, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 73 away from 97, we end up with 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 73

Going ahead to step 3:
If we divide 247 by 73, we get 3 and a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 219 away from 247, we end up with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 73

On to step 4:
If we divide 284 by 73, we get 3 and a remainder of 65.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 219 from 284 leaves us with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 73

Moving on to step 5:
If we divide 658 by 73, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1339.0
Subtracting 657 from 658 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 73

Going ahead to step 6:
73 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 13390.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
73 goes into 180 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 13390.2
If we take 146 away from 180, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 73, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 13390.24
Deduct 292 from 340 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 73, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 13390.246
If we take 438 away from 480, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 73 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 13390.2465
If we take 365 away from 420, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
550 divided by 73 is 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 13390.24657
Subtract 511 from 550 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
When dividing 390 by 73, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13390.246575
The remainder is 25 after subtracting 365 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
250 divided by 73 is 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 13390.2465753
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
310 divided by 73 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 13390.24657534
Subtract 292 from 310 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 13390.24657534 and a remainder of 1.8e-08.
