9009130 ÷ 278 
The aim is to understand the frequency of 278 in 9009130.

On to step 1:
The number 278 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 278

Step 2:
When dividing 90 by 278, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 278

On to step 3:
900 divided by 278 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 834 from 900, we get 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 278

Step 4:
The number 278 fits into 669 2 times, leaving a remainder of 113.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 556 away from 669, we end up with 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 278

Let's proceed to step 5:
If we divide 1131 by 278, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 324.0
The remainder is 19 after subtracting 1112 from 1131.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 278

Let's proceed to step 6:
When dividing 193 by 278, we get 0 with a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 3240.0
The remainder is 193 after subtracting 0 from 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 278

Let's proceed to step 7:
278 can be fit into 1930 6 times, resulting in a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 32406.0
The remainder is 262 after subtracting 1668 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 8:
When dividing 2620 by 278, we get 9 with a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 32406.9
If we take 2502 away from 2620, we end up with 118.
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 9:
278 can be fit into 1180 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 32406.94
Subtracting 1112 from 1180 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
278 goes into 680 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 32406.942
If we subtract 556 from 680, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
278 can be fit into 1240 4 times, resulting in a remainder of 128.
The next digit of our result is 4. 
Result so far: 32406.9424
The remainder is 128 after subtracting 1112 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
The number 278 fits into 1280 4 times, leaving a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 32406.94244
If we subtract 1112 from 1280, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 32406.94244, with a leftover of 0.000168.
