99453746 ÷ 431 
The aim is to understand the frequency of 431 in 99453746.

Advancing to step 1:
431 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 431

Moving on to step 2:
431 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 431

On to step 3:
431 can be fit into 994 2 times, resulting in a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 862 from 994, we get 132.
Take the next digit (5) from the dividend and append it to 132, then repeat: 1325 / 431

Advancing to step 4:
The number 431 fits into 1325 3 times, leaving a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 1293 from 1325 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 431

Moving on to step 5:
431 goes into 323 0 times with a remainder of 323.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
If we take 0 away from 323, we end up with 323.
Append the next digit (7) from the dividend to 323 and continue with: 3237 / 431

On to step 6:
If we divide 3237 by 431, we get 7 and a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 2307.0
If we subtract 3017 from 3237, we get 220.
Append the next digit (4) from the dividend to 220 and continue with: 2204 / 431

Let's proceed to step 7:
431 goes into 2204 5 times with a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 23075.0
If we take 2155 away from 2204, we end up with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 431

Moving on to step 8:
When dividing 496 by 431, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 230751.0
Deduct 431 from 496 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
431 goes into 650 1 times with a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 230751.1
Subtracting 431 from 650 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 10:
When dividing 2190 by 431, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 230751.15
If we subtract 2155 from 2190, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
The number 431 fits into 350 0 times, leaving a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 230751.15
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
The number 431 fits into 3500 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 230751.1508
Subtract 3448 from 3500 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
520 divided by 431 is 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 230751.15081
Deduct 431 from 520 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
The number 431 fits into 890 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 230751.150812
If we subtract 862 from 890, we 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.

Advancing to step 15:
The number 431 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 230751.150812
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
2800 divided by 431 is 6 with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 230751.15081206
The remainder is 214 after subtracting 2586 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

In conclusion, the division gives 230751.15081206 with a balance of 2.14e-07.
