72191498 divided by 432 
The aim is to understand the frequency of 432 in 72191498.

Going ahead to step 1:
432 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 432

Step 2:
When dividing 72 by 432, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 432

Advancing to step 3:
The number 432 fits into 721 1 times, leaving a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 432 from 721 and we're left with 289.
Append the next digit (9) from the dividend to 289 and continue with: 2899 / 432

Step 4:
If we divide 2899 by 432, we get 6 and a remainder of 307.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2592 from 2899, we get 307.
Include the next digit (1) from the dividend after 307, then repeat: 3071 / 432

Going ahead to step 5:
The number 432 fits into 3071 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 167.0
Deduct 3024 from 3071 and we're left with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 432

Let's proceed to step 6:
432 goes into 474 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1671.0
If we subtract 432 from 474, we get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 432

Step 7:
When dividing 429 by 432, we get 0 with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 16710.0
If we take 0 away from 429, we end up with 429.
Take the next digit (8) from the dividend and append it to 429, then repeat: 4298 / 432

On to step 8:
The number 432 fits into 4298 9 times, leaving a remainder of 410.
Record the quotient 9 as the next digit in the result. 
Result so far: 167109.0
Deduct 3888 from 4298 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 9:
When dividing 4100 by 432, we get 9 with a remainder of 212.
The number 9 becomes the next digit in our result. 
Result so far: 167109.9
Subtracting 3888 from 4100 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
432 can be fit into 2120 4 times, resulting in a remainder of 392.
Put 4 as the next digit of the answer. 
Result so far: 167109.94
Deduct 1728 from 2120 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 11:
If we divide 3920 by 432, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 167109.949
If we subtract 3888 from 3920, we 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.

Moving on to step 12:
When dividing 320 by 432, we get 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 167109.949
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
3200 divided by 432 is 7 with a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 167109.94907
If we take 3024 away from 3200, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
432 goes into 1760 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 167109.949074
Subtracting 1728 from 1760 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
When dividing 320 by 432, we get 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 167109.949074
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 16:
432 can be fit into 3200 7 times, resulting in a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 167109.94907407
The remainder is 176 after subtracting 3024 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 167109.94907407, with a leftover of 1.76e-07.
