9353781 ÷ 253 
The aim is to understand the frequency of 253 in 9353781.

Moving on to step 1:
9 divided by 253 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 253

On to step 2:
253 can be fit into 93 0 times, resulting in a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 93, we get 93.
Fetch the next digit (5) from the dividend, attach it to 93 and continue: 935 / 253

Let's proceed to step 3:
When dividing 935 by 253, we get 3 with a remainder of 176.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 759 from 935 leaves us with 176.
Fetch the next digit (3) from the dividend, attach it to 176 and continue: 1763 / 253

On to step 4:
1763 divided by 253 is 6 with a remainder of 245.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 1518 from 1763, we get 245.
Include the next digit (7) from the dividend after 245, then repeat: 2457 / 253

Moving on to step 5:
When dividing 2457 by 253, we get 9 with a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 369.0
If we take 2277 away from 2457, we end up with 180.
Include the next digit (8) from the dividend after 180, then repeat: 1808 / 253

On to step 6:
When dividing 1808 by 253, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3697.0
The remainder is 37 after subtracting 1771 from 1808.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 253

Going ahead to step 7:
The number 253 fits into 371 1 times, leaving a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 36971.0
The remainder is 118 after subtracting 253 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 8:
253 goes into 1180 4 times with a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 36971.4
The remainder is 168 after subtracting 1012 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
If we divide 1680 by 253, we get 6 and a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 36971.46
Deduct 1518 from 1680 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 10:
If we divide 1620 by 253, we get 6 and a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 36971.466
If we take 1518 away from 1620, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 36971.466 with a remainder of 0.0102.
