Let's divide 55130533 by 378
The aim is to understand the frequency of 378 in 55130533.

Advancing to step 1:
When dividing 5 by 378, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 378

Going ahead to step 2:
378 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 378

On to step 3:
551 divided by 378 is 1 with a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 378 from 551, we get 173.
Bring next digit (3) of the dividend behind the 173 and repeat the process: 1733 / 378

On to step 4:
The number 378 fits into 1733 4 times, leaving a remainder of 221.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 1512 from 1733 leaves us with 221.
Include the next digit (0) from the dividend after 221, then repeat: 2210 / 378

Advancing to step 5:
If we divide 2210 by 378, we get 5 and a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtract 1890 from 2210 to get 320.
Bring next digit (5) of the dividend behind the 320 and repeat the process: 3205 / 378

Step 6:
3205 divided by 378 is 8 with a remainder of 181.
Record the quotient 8 as the next digit in the result. 
Result so far: 1458.0
Subtract 3024 from 3205 to get 181.
Grab the next digit (3) from the dividend, add it to 181, then carry on: 1813 / 378

Advancing to step 7:
378 goes into 1813 4 times with a remainder of 301.
The next digit of our result is 4. 
Result so far: 14584.0
Subtract 1512 from 1813 to get 301.
Take the next digit (3) from the dividend and append it to 301, then repeat: 3013 / 378

Advancing to step 8:
If we divide 3013 by 378, we get 7 and a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 145847.0
Subtract 2646 from 3013 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 9:
378 can be fit into 3670 9 times, resulting in a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 145847.9
If we subtract 3402 from 3670, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 10:
The number 378 fits into 2680 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 145847.97
Subtracting 2646 from 2680 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
378 can be fit into 340 0 times, resulting in a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 145847.97
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
378 goes into 3400 8 times with a remainder of 376.
The next digit of our result is 8. 
Result so far: 145847.9708
If we subtract 3024 from 3400, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 13:
When dividing 3760 by 378, we get 9 with a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 145847.97089
The remainder is 358 after subtracting 3402 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 14:
If we divide 3580 by 378, we get 9 and a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 145847.970899
The remainder is 178 after subtracting 3402 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The quotient of the division is 145847.970899, and the remainder is 1.78e-05.
