We're dividing 10707066 by 378 
The aim is to understand the frequency of 378 in 10707066.

Let's proceed to step 1:
1 divided by 378 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 378

On to step 2:
378 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 378

On to step 3:
The number 378 fits into 107 0 times, leaving a remainder of 107.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 107 after subtracting 0 from 107.
Include the next digit (0) from the dividend after 107, then repeat: 1070 / 378

Going ahead to step 4:
If we divide 1070 by 378, we get 2 and a remainder of 314.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 314 after subtracting 756 from 1070.
Include the next digit (7) from the dividend after 314, then repeat: 3147 / 378

Moving on to step 5:
378 goes into 3147 8 times with a remainder of 123.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 3024 from 3147 leaves us with 123.
Bring next digit (0) of the dividend behind the 123 and repeat the process: 1230 / 378

Let's proceed to step 6:
If we divide 1230 by 378, we get 3 and a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Deduct 1134 from 1230 and we're left with 96.
Grab the next digit (6) from the dividend, add it to 96, then carry on: 966 / 378

Advancing to step 7:
966 divided by 378 is 2 with a remainder of 210.
The next digit of our result is 2. 
Result so far: 2832.0
If we take 756 away from 966, we end up with 210.
Bring next digit (6) of the dividend behind the 210 and repeat the process: 2106 / 378

Moving on to step 8:
378 goes into 2106 5 times with a remainder of 216.
Record the quotient 5 as the next digit in the result. 
Result so far: 28325.0
Subtract 1890 from 2106 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 9:
If we divide 2160 by 378, we get 5 and a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 28325.5
Subtracting 1890 from 2160 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
378 goes into 2700 7 times with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 28325.57
Deduct 2646 from 2700 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
The number 378 fits into 540 1 times, leaving a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 28325.571
Deduct 378 from 540 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.

Step 12:
When dividing 1620 by 378, we get 4 with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 28325.5714
Subtract 1512 from 1620 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
When dividing 1080 by 378, we get 2 with a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 28325.57142
If we subtract 756 from 1080, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 14:
378 goes into 3240 8 times with a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 28325.571428
Subtract 3024 from 3240 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
If we divide 2160 by 378, we get 5 and a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 28325.5714285
Subtract 1890 from 2160 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 16:
378 can be fit into 2700 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 28325.57142857
Subtracting 2646 from 2700 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 28325.57142857 with a remainder of 5.4e-08.
