We divide 9112570 by 355
The aim is to understand the frequency of 355 in 9112570.

Let's proceed to step 1:
355 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 355

Advancing to step 2:
When dividing 91 by 355, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 355

On to step 3:
355 goes into 911 2 times with a remainder of 201.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 710 from 911 leaves us with 201.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 355

Advancing to step 4:
2012 divided by 355 is 5 with a remainder of 237.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 1775 from 2012 leaves us with 237.
Fetch the next digit (5) from the dividend, attach it to 237 and continue: 2375 / 355

Advancing to step 5:
2375 divided by 355 is 6 with a remainder of 245.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
If we subtract 2130 from 2375, we get 245.
Fetch the next digit (7) from the dividend, attach it to 245 and continue: 2457 / 355

Advancing to step 6:
When dividing 2457 by 355, we get 6 with a remainder of 327.
Write down 6 as next digit of the result. 
Result so far: 2566.0
Subtract 2130 from 2457 to get 327.
Include the next digit (0) from the dividend after 327, then repeat: 3270 / 355

Moving on to step 7:
When dividing 3270 by 355, we get 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 25669.0
If we subtract 3195 from 3270, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
The number 355 fits into 750 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 25669.2
Subtract 710 from 750 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 355, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 25669.21
If we take 355 away from 400, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
The number 355 fits into 450 1 times, leaving a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 25669.211
Deduct 355 from 450 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The quotient of the division is 25669.211, and the remainder is 0.0095.
