10556083 divided by 378 
The aim is to understand the frequency of 378 in 10556083.

Let's proceed to step 1:
If we divide 1 by 378, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 378

Let's proceed to step 2:
When dividing 10 by 378, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 378

Moving on to step 3:
105 divided by 378 is 0 with a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 105 and we're left with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 378

Advancing to step 4:
The number 378 fits into 1055 2 times, leaving a remainder of 299.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 756 from 1055 to get 299.
Take the next digit (6) from the dividend and append it to 299, then repeat: 2996 / 378

Step 5:
378 goes into 2996 7 times with a remainder of 350.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 2646 from 2996, we get 350.
Fetch the next digit (0) from the dividend, attach it to 350 and continue: 3500 / 378

Let's proceed to step 6:
The number 378 fits into 3500 9 times, leaving a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 3402 from 3500 and we're left with 98.
Grab the next digit (8) from the dividend, add it to 98, then carry on: 988 / 378

Going ahead to step 7:
If we divide 988 by 378, we get 2 and a remainder of 232.
The next digit of our result is 2. 
Result so far: 2792.0
Subtract 756 from 988 to get 232.
Bring next digit (3) of the dividend behind the 232 and repeat the process: 2323 / 378

Moving on to step 8:
When dividing 2323 by 378, we get 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 27926.0
Deduct 2268 from 2323 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
The number 378 fits into 550 1 times, leaving a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 27926.1
The remainder is 172 after subtracting 378 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 10:
1720 divided by 378 is 4 with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 27926.14
If we take 1512 away from 1720, we end up 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.

Step 11:
The number 378 fits into 2080 5 times, leaving a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 27926.145
Subtract 1890 from 2080 to 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 12:
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: 27926.1455
If we take 1890 away from 1900, we end up 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.

Our division results in 27926.1455 with a remaining 0.0001.
