Let's divide 35249568 by 801
The aim is to understand the frequency of 801 in 35249568.

Moving on to step 1:
801 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 801

Let's proceed to step 2:
35 divided by 801 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 801

Advancing to step 3:
If we divide 352 by 801, we get 0 and a remainder of 352.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 352, we get 352.
Take the next digit (4) from the dividend and append it to 352, then repeat: 3524 / 801

Moving on to step 4:
When dividing 3524 by 801, we get 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3204 away from 3524, we end up with 320.
Include the next digit (9) from the dividend after 320, then repeat: 3209 / 801

On to step 5:
801 can be fit into 3209 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 5 after subtracting 3204 from 3209.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 801

Moving on to step 6:
The number 801 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 440.0
Subtract 0 from 55 to get 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 801

Advancing to step 7:
If we divide 556 by 801, we get 0 and a remainder of 556.
The number 0 becomes the next digit in our result. 
Result so far: 4400.0
If we take 0 away from 556, we end up with 556.
Take the next digit (8) from the dividend and append it to 556, then repeat: 5568 / 801

On to step 8:
When dividing 5568 by 801, we get 6 with a remainder of 762.
Put 6 as the next digit of the answer. 
Result so far: 44006.0
The remainder is 762 after subtracting 4806 from 5568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 9:
The number 801 fits into 7620 9 times, leaving a remainder of 411.
Use 9 as the next digit of our solution. 
Result so far: 44006.9
The remainder is 411 after subtracting 7209 from 7620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 10:
When dividing 4110 by 801, we get 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 44006.95
Subtract 4005 from 4110 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 11:
The number 801 fits into 1050 1 times, leaving a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 44006.951
Deduct 801 from 1050 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 12:
When dividing 2490 by 801, we get 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 44006.9513
If we take 2403 away from 2490, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 13:
When dividing 870 by 801, we get 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 44006.95131
Subtract 801 from 870 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 14:
801 goes into 690 0 times with a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 44006.95131
Subtract 0 from 690 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 15:
801 can be fit into 6900 8 times, resulting in a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 44006.9513108
Deduct 6408 from 6900 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 16:
When dividing 4920 by 801, we get 6 with a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 44006.95131086
If we subtract 4806 from 4920, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 44006.95131086 with a remainder of 1.14e-07.
