We're dividing 16258835 by 435 
The aim is to understand the frequency of 435 in 16258835.

Let's proceed to step 1:
If we divide 1 by 435, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 435

Advancing to step 2:
The number 435 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 435

On to step 3:
435 goes into 162 0 times with a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 162 leaves us with 162.
Bring next digit (5) of the dividend behind the 162 and repeat the process: 1625 / 435

Step 4:
If we divide 1625 by 435, we get 3 and a remainder of 320.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1305 from 1625 leaves us with 320.
Append the next digit (8) from the dividend to 320 and continue with: 3208 / 435

Let's proceed to step 5:
If we divide 3208 by 435, we get 7 and a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 3045 from 3208 and we're left with 163.
Bring next digit (8) of the dividend behind the 163 and repeat the process: 1638 / 435

On to step 6:
If we divide 1638 by 435, we get 3 and a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
If we subtract 1305 from 1638, we get 333.
Take the next digit (3) from the dividend and append it to 333, then repeat: 3333 / 435

Let's proceed to step 7:
The number 435 fits into 3333 7 times, leaving a remainder of 288.
Use 7 as the next digit of our solution. 
Result so far: 3737.0
Deduct 3045 from 3333 and we're left with 288.
Include the next digit (5) from the dividend after 288, then repeat: 2885 / 435

On to step 8:
If we divide 2885 by 435, we get 6 and a remainder of 275.
Record the quotient 6 as the next digit in the result. 
Result so far: 37376.0
The remainder is 275 after subtracting 2610 from 2885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 9:
If we divide 2750 by 435, we get 6 and a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 37376.6
Subtracting 2610 from 2750 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 435 fits into 1400 3 times, leaving a remainder of 95.
Write down 3 as next digit of the result. 
Result so far: 37376.63
If we subtract 1305 from 1400, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
When dividing 950 by 435, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 37376.632
Subtract 870 from 950 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.

Moving on to step 12:
435 can be fit into 800 1 times, resulting in a remainder of 365.
The next digit of our result is 1. 
Result so far: 37376.6321
The remainder is 365 after subtracting 435 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 13:
3650 divided by 435 is 8 with a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 37376.63218
If we take 3480 away from 3650, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
The number 435 fits into 1700 3 times, leaving a remainder of 395.
Use 3 as the next digit of our solution. 
Result so far: 37376.632183
Subtract 1305 from 1700 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 15:
When dividing 3950 by 435, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 37376.6321839
Subtracting 3915 from 3950 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 16:
If we divide 350 by 435, we get 0 and a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 37376.6321839
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.

Our division results in 37376.6321839 with a remaining 3.5e-07.
