We're dividing 885872 by 73 
The aim is to understand the frequency of 73 in 885872.

On to step 1:
When dividing 8 by 73, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 73

Advancing to step 2:
The number 73 fits into 88 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 73 from 88 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 73

Step 3:
155 divided by 73 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 146 away from 155, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 73

Step 4:
When dividing 98 by 73, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 25 after subtracting 73 from 98.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 73

Step 5:
73 goes into 257 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 1213.0
If we subtract 219 from 257, we get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 73

Moving on to step 6:
If we divide 382 by 73, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 12135.0
Deduct 365 from 382 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 73 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12135.2
If we subtract 146 from 170, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
73 goes into 240 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 12135.23
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
The number 73 fits into 210 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12135.232
Deduct 146 from 210 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
The number 73 fits into 640 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 12135.2328
Subtract 584 from 640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
73 goes into 560 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 12135.23287
Subtracting 511 from 560 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
If we divide 490 by 73, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 12135.232876
If we subtract 438 from 490, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
The number 73 fits into 520 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 12135.2328767
Deduct 511 from 520 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
When dividing 90 by 73, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 12135.23287671
The remainder is 17 after subtracting 73 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 12135.23287671 with a balance of 1.7e-08.
