Let's divide 49786948 by 378
The aim is to understand the frequency of 378 in 49786948.

On to step 1:
378 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 378

Let's proceed to step 2:
When dividing 49 by 378, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 378

Let's proceed to step 3:
When dividing 497 by 378, we get 1 with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 378 from 497, we get 119.
Bring next digit (8) of the dividend behind the 119 and repeat the process: 1198 / 378

Advancing to step 4:
The number 378 fits into 1198 3 times, leaving a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1134 from 1198, we get 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 378

Moving on to step 5:
If we divide 646 by 378, we get 1 and a remainder of 268.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 378 from 646 and we're left with 268.
Take the next digit (9) from the dividend and append it to 268, then repeat: 2689 / 378

Advancing to step 6:
When dividing 2689 by 378, we get 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 1317.0
Deduct 2646 from 2689 and we're left with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 378

Step 7:
When dividing 434 by 378, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 13171.0
Subtracting 378 from 434 leaves us with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 378

Moving on to step 8:
568 divided by 378 is 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 131711.0
If we subtract 378 from 568, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
378 goes into 1900 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 131711.5
Deduct 1890 from 1900 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 378, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 131711.5
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
378 can be fit into 1000 2 times, resulting in a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 131711.502
If we subtract 756 from 1000, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 12:
When dividing 2440 by 378, we get 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 131711.5026
Deduct 2268 from 2440 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 13:
378 can be fit into 1720 4 times, resulting in a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 131711.50264
Deduct 1512 from 1720 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
When dividing 2080 by 378, we get 5 with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 131711.502645
If we subtract 1890 from 2080, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
When dividing 1900 by 378, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 131711.5026455
Subtracting 1890 from 1900 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 131711.5026455 with a remainder of 1e-07.
