We're dividing 83584198 by 72 
The aim is to understand the frequency of 72 in 83584198.

Let's proceed to step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 72

Moving on to step 2:
If we divide 83 by 72, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 83 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 72

Moving on to step 3:
The number 72 fits into 115 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 43 after subtracting 72 from 115.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 72

Step 4:
When dividing 438 by 72, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 432 from 438 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 72

Moving on to step 5:
The number 72 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
If we subtract 0 from 64, we get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 72

Advancing to step 6:
When dividing 641 by 72, we get 8 with a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 11608.0
If we subtract 576 from 641, we get 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 72

Moving on to step 7:
The number 72 fits into 659 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 116089.0
If we subtract 648 from 659, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 72

Step 8:
When dividing 118 by 72, we get 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1160891.0
If we take 72 away from 118, we end up 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.

Let's proceed to step 9:
72 can be fit into 460 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1160891.6
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 72 fits into 280 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 1160891.63
Subtracting 216 from 280 leaves us 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.

Going ahead to step 11:
640 divided by 72 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 1160891.638
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 1160891.6388
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 1160891.6388 and a remainder of 0.00064.
