2286315 ÷ 378 
The aim is to understand the frequency of 378 in 2286315.

Step 1:
378 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 378

Let's proceed to step 2:
When dividing 22 by 378, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 378

Going ahead to step 3:
378 goes into 228 0 times with a remainder of 228.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 228 to get 228.
Append the next digit (6) from the dividend to 228 and continue with: 2286 / 378

On to step 4:
When dividing 2286 by 378, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 18 after subtracting 2268 from 2286.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 378

Moving on to step 5:
378 goes into 183 0 times with a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 183 leaves us with 183.
Fetch the next digit (1) from the dividend, attach it to 183 and continue: 1831 / 378

Let's proceed to step 6:
When dividing 1831 by 378, we get 4 with a remainder of 319.
Write down 4 as next digit of the result. 
Result so far: 604.0
If we subtract 1512 from 1831, we get 319.
Grab the next digit (5) from the dividend, add it to 319, then carry on: 3195 / 378

Advancing to step 7:
If we divide 3195 by 378, we get 8 and a remainder of 171.
The next digit of our result is 8. 
Result so far: 6048.0
If we take 3024 away from 3195, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 8:
378 can be fit into 1710 4 times, resulting in a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 6048.4
The remainder is 198 after subtracting 1512 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 9:
378 can be fit into 1980 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 6048.45
If we subtract 1890 from 1980, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
378 can be fit into 900 2 times, resulting in a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 6048.452
Subtract 756 from 900 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
If we divide 1440 by 378, we get 3 and a remainder of 306.
The next digit of our result is 3. 
Result so far: 6048.4523
Deduct 1134 from 1440 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 12:
378 can be fit into 3060 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 6048.45238
Subtract 3024 from 3060 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
The number 378 fits into 360 0 times, leaving a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 6048.45238
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 14:
3600 divided by 378 is 9 with a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 6048.4523809
The remainder is 198 after subtracting 3402 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 15:
The number 378 fits into 1980 5 times, leaving a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 6048.45238095
If we subtract 1890 from 1980, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 6048.45238095 and a remainder of 9e-08.
