We're dividing 148415 by 72 
The aim is to understand the frequency of 72 in 148415.

Advancing to step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 72

Going ahead to step 2:
When dividing 14 by 72, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 72

Step 3:
If we divide 148 by 72, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 144 from 148 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 72

On to step 4:
72 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 44 to get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 72

Going ahead to step 5:
If we divide 441 by 72, we get 6 and a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we take 432 away from 441, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 72

Step 6:
The number 72 fits into 95 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 2061.0
If we take 72 away from 95, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 72 fits into 230 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2061.3
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 72, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 2061.31
If we subtract 72 from 140, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
72 can be fit into 680 9 times, resulting in a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 2061.319
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2061.3194
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
The number 72 fits into 320 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2061.31944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 2061.31944, and the remainder is 3.2e-05.
