51242374 ÷ 435 
The aim is to understand the frequency of 435 in 51242374.

Moving on to step 1:
5 divided by 435 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 435

Advancing to step 2:
51 divided by 435 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 435

Moving on to step 3:
512 divided by 435 is 1 with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 77 after subtracting 435 from 512.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 435

Advancing to step 4:
435 goes into 774 1 times with a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 435 from 774 to get 339.
Bring next digit (2) of the dividend behind the 339 and repeat the process: 3392 / 435

Going ahead to step 5:
The number 435 fits into 3392 7 times, leaving a remainder of 347.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 3045 away from 3392, we end up with 347.
Grab the next digit (3) from the dividend, add it to 347, then carry on: 3473 / 435

Step 6:
If we divide 3473 by 435, we get 7 and a remainder of 428.
Put 7 as the next digit of the answer. 
Result so far: 1177.0
Subtracting 3045 from 3473 leaves us with 428.
Bring next digit (7) of the dividend behind the 428 and repeat the process: 4287 / 435

Advancing to step 7:
4287 divided by 435 is 9 with a remainder of 372.
Put 9 as the next digit of the answer. 
Result so far: 11779.0
Subtracting 3915 from 4287 leaves us with 372.
Take the next digit (4) from the dividend and append it to 372, then repeat: 3724 / 435

Going ahead to step 8:
435 goes into 3724 8 times with a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 117798.0
Deduct 3480 from 3724 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 9:
If we divide 2440 by 435, we get 5 and a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 117798.5
Deduct 2175 from 2440 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
435 can be fit into 2650 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 117798.56
If we subtract 2610 from 2650, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
435 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 117798.56
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
4000 divided by 435 is 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 117798.5609
Subtract 3915 from 4000 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
The number 435 fits into 850 1 times, leaving a remainder of 415.
Put 1 as the next digit of the answer. 
Result so far: 117798.56091
Subtracting 435 from 850 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 14:
If we divide 4150 by 435, we get 9 and a remainder of 235.
Record the quotient 9 as the next digit in the result. 
Result so far: 117798.560919
Deduct 3915 from 4150 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 15:
When dividing 2350 by 435, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 117798.5609195
Subtracting 2175 from 2350 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 16:
435 goes into 1750 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 117798.56091954
The remainder is 10 after subtracting 1740 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 117798.56091954, with a leftover of 1e-08.
