35286900 ÷ 240 
The aim is to understand the frequency of 240 in 35286900.

Advancing to step 1:
If we divide 3 by 240, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 240

On to step 2:
The number 240 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 240

Step 3:
240 goes into 352 1 times with a remainder of 112.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 112 after subtracting 240 from 352.
Include the next digit (8) from the dividend after 112, then repeat: 1128 / 240

On to step 4:
1128 divided by 240 is 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 960 from 1128 to get 168.
Include the next digit (6) from the dividend after 168, then repeat: 1686 / 240

On to step 5:
240 can be fit into 1686 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 147.0
Subtract 1680 from 1686 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 240

On to step 6:
240 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 1470.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 240

Advancing to step 7:
If we divide 690 by 240, we get 2 and a remainder of 210.
The number 2 becomes the next digit in our result. 
Result so far: 14702.0
If we take 480 away from 690, we end up with 210.
Grab the next digit (0) from the dividend, add it to 210, then carry on: 2100 / 240

Step 8:
240 goes into 2100 8 times with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 147028.0
Subtract 1920 from 2100 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
When dividing 1800 by 240, we get 7 with a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 147028.7
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
1200 divided by 240 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 147028.75
Deduct 1200 from 1200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 240, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 147028.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
240 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 147028.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 147028.75, with a leftover of 0.0.
