We divide 20434497 by 72
The aim is to understand the frequency of 72 in 20434497.

Going ahead to step 1:
72 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 72

On to step 2:
The number 72 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 72

On to step 3:
When dividing 204 by 72, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 144 from 204 to get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 72

Advancing to step 4:
The number 72 fits into 603 8 times, leaving a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 576 from 603 leaves us with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 72

On to step 5:
274 divided by 72 is 3 with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Subtract 216 from 274 to get 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 72

Let's proceed to step 6:
If we divide 584 by 72, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 2838.0
Subtract 576 from 584 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 72

Step 7:
89 divided by 72 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 28381.0
The remainder is 17 after subtracting 72 from 89.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 72

Advancing to step 8:
The number 72 fits into 177 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 283812.0
Subtract 144 from 177 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 72 fits into 330 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 283812.4
Subtracting 288 from 330 leaves us 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.

On to step 10:
72 can be fit into 420 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 283812.45
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
72 goes into 600 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 283812.458
Subtract 576 from 600 to 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.

Moving on to step 12:
240 divided by 72 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 283812.4583
Subtract 216 from 240 to 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.

Going ahead to step 13:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 283812.45833
If we subtract 216 from 240, 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.

The final outcome is 283812.45833, with a leftover of 2.4e-05.
