We look at the division of 80694236 by 535 
The aim is to understand the frequency of 535 in 80694236.

On to step 1:
The number 535 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 535

Moving on to step 2:
80 divided by 535 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 535

Let's proceed to step 3:
806 divided by 535 is 1 with a remainder of 271.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 271 after subtracting 535 from 806.
Take the next digit (9) from the dividend and append it to 271, then repeat: 2719 / 535

Let's proceed to step 4:
If we divide 2719 by 535, we get 5 and a remainder of 44.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2675 away from 2719, we end up with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 535

Going ahead to step 5:
535 goes into 444 0 times with a remainder of 444.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Deduct 0 from 444 and we're left with 444.
Fetch the next digit (2) from the dividend, attach it to 444 and continue: 4442 / 535

Going ahead to step 6:
535 goes into 4442 8 times with a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 1508.0
Deduct 4280 from 4442 and we're left with 162.
Bring next digit (3) of the dividend behind the 162 and repeat the process: 1623 / 535

Moving on to step 7:
If we divide 1623 by 535, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 15083.0
Subtract 1605 from 1623 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 535

Advancing to step 8:
If we divide 186 by 535, we get 0 and a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 150830.0
If we take 0 away from 186, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
If we divide 1860 by 535, we get 3 and a remainder of 255.
The next digit of our result is 3. 
Result so far: 150830.3
If we subtract 1605 from 1860, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 10:
When dividing 2550 by 535, we get 4 with a remainder of 410.
Use 4 as the next digit of our solution. 
Result so far: 150830.34
Deduct 2140 from 2550 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 11:
The number 535 fits into 4100 7 times, leaving a remainder of 355.
Use 7 as the next digit of our solution. 
Result so far: 150830.347
If we take 3745 away from 4100, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 12:
535 can be fit into 3550 6 times, resulting in a remainder of 340.
The next digit of our result is 6. 
Result so far: 150830.3476
Deduct 3210 from 3550 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
If we divide 3400 by 535, we get 6 and a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 150830.34766
If we subtract 3210 from 3400, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 150830.34766, with a leftover of 0.00019.
