16265861 ÷ 432 
The aim is to understand the frequency of 432 in 16265861.

Moving on to step 1:
When dividing 1 by 432, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 432

Going ahead to step 2:
432 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 432

Advancing to step 3:
If we divide 162 by 432, we get 0 and a remainder of 162.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 162 leaves us with 162.
Fetch the next digit (6) from the dividend, attach it to 162 and continue: 1626 / 432

On to step 4:
If we divide 1626 by 432, we get 3 and a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1296 from 1626 and we're left with 330.
Fetch the next digit (5) from the dividend, attach it to 330 and continue: 3305 / 432

Let's proceed to step 5:
The number 432 fits into 3305 7 times, leaving a remainder of 281.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 3024 from 3305 to get 281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 432

Going ahead to step 6:
The number 432 fits into 2818 6 times, leaving a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 376.0
The remainder is 226 after subtracting 2592 from 2818.
Include the next digit (6) from the dividend after 226, then repeat: 2266 / 432

Going ahead to step 7:
432 goes into 2266 5 times with a remainder of 106.
The number 5 becomes the next digit in our result. 
Result so far: 3765.0
If we take 2160 away from 2266, we end up with 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 432

Let's proceed to step 8:
432 can be fit into 1061 2 times, resulting in a remainder of 197.
Use 2 as the next digit of our solution. 
Result so far: 37652.0
Subtract 864 from 1061 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 9:
432 goes into 1970 4 times with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 37652.4
Subtracting 1728 from 1970 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
If we divide 2420 by 432, we get 5 and a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 37652.45
The remainder is 260 after subtracting 2160 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 11:
If we divide 2600 by 432, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 37652.456
If we subtract 2592 from 2600, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 432 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 37652.456
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 432 fits into 800 1 times, leaving a remainder of 368.
The next digit of our result is 1. 
Result so far: 37652.45601
Subtract 432 from 800 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 14:
When dividing 3680 by 432, we get 8 with a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 37652.456018
Subtract 3456 from 3680 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 15:
432 goes into 2240 5 times with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 37652.4560185
Subtract 2160 from 2240 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
When dividing 800 by 432, we get 1 with a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 37652.45601851
Subtract 432 from 800 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 37652.45601851 with a balance of 3.68e-07.
