42997439 divided by 535 
The aim is to understand the frequency of 535 in 42997439.

Going ahead to step 1:
If we divide 4 by 535, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 535

Step 2:
42 divided by 535 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 535

Moving on to step 3:
The number 535 fits into 429 0 times, leaving a remainder of 429.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 429, we end up with 429.
Take the next digit (9) from the dividend and append it to 429, then repeat: 4299 / 535

Step 4:
The number 535 fits into 4299 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 4280 from 4299 and we're left with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 535

Going ahead to step 5:
535 can be fit into 197 0 times, resulting in a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 197 leaves us with 197.
Include the next digit (4) from the dividend after 197, then repeat: 1974 / 535

Going ahead to step 6:
When dividing 1974 by 535, we get 3 with a remainder of 369.
Use 3 as the next digit of our solution. 
Result so far: 803.0
If we take 1605 away from 1974, we end up with 369.
Fetch the next digit (3) from the dividend, attach it to 369 and continue: 3693 / 535

Let's proceed to step 7:
If we divide 3693 by 535, we get 6 and a remainder of 483.
Record the quotient 6 as the next digit in the result. 
Result so far: 8036.0
Subtracting 3210 from 3693 leaves us with 483.
Append the next digit (9) from the dividend to 483 and continue with: 4839 / 535

Going ahead to step 8:
If we divide 4839 by 535, we get 9 and a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 80369.0
Subtract 4815 from 4839 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 535, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 80369.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
535 can be fit into 2400 4 times, resulting in a remainder of 260.
Put 4 as the next digit of the answer. 
Result so far: 80369.04
Subtract 2140 from 2400 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
535 can be fit into 2600 4 times, resulting in a remainder of 460.
The number 4 becomes the next digit in our result. 
Result so far: 80369.044
If we take 2140 away from 2600, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 80369.044, with a leftover of 0.046.
