Let's divide 31660234 by 535
The aim is to understand the frequency of 535 in 31660234.

On to step 1:
535 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 535

Step 2:
When dividing 31 by 535, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 535

On to step 3:
535 goes into 316 0 times with a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Bring next digit (6) of the dividend behind the 316 and repeat the process: 3166 / 535

Advancing to step 4:
When dividing 3166 by 535, we get 5 with a remainder of 491.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2675 from 3166 leaves us with 491.
Include the next digit (0) from the dividend after 491, then repeat: 4910 / 535

Moving on to step 5:
4910 divided by 535 is 9 with a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 4815 from 4910, we get 95.
Bring next digit (2) of the dividend behind the 95 and repeat the process: 952 / 535

On to step 6:
If we divide 952 by 535, we get 1 and a remainder of 417.
The next digit of our result is 1. 
Result so far: 591.0
Deduct 535 from 952 and we're left with 417.
Fetch the next digit (3) from the dividend, attach it to 417 and continue: 4173 / 535

Advancing to step 7:
535 can be fit into 4173 7 times, resulting in a remainder of 428.
The next digit of our result is 7. 
Result so far: 5917.0
If we subtract 3745 from 4173, we get 428.
Take the next digit (4) from the dividend and append it to 428, then repeat: 4284 / 535

Step 8:
535 goes into 4284 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 59178.0
Subtracting 4280 from 4284 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
535 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 59178.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
535 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 59178.0
Deduct 0 from 400 and we're left 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.

The final result is 59178.0 with a remainder of 0.4.
