We divide 55258517 by 378
The aim is to understand the frequency of 378 in 55258517.

Let's proceed to step 1:
When dividing 5 by 378, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 378

Advancing to step 2:
If we divide 55 by 378, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 378

Moving on to step 3:
When dividing 552 by 378, we get 1 with a remainder of 174.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 378 from 552, we get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 378

On to step 4:
When dividing 1745 by 378, we get 4 with a remainder of 233.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1512 from 1745, we get 233.
Bring next digit (8) of the dividend behind the 233 and repeat the process: 2338 / 378

Going ahead to step 5:
378 can be fit into 2338 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we subtract 2268 from 2338, we get 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 378

Advancing to step 6:
If we divide 705 by 378, we get 1 and a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 1461.0
If we subtract 378 from 705, we get 327.
Grab the next digit (1) from the dividend, add it to 327, then carry on: 3271 / 378

Let's proceed to step 7:
3271 divided by 378 is 8 with a remainder of 247.
The number 8 becomes the next digit in our result. 
Result so far: 14618.0
Deduct 3024 from 3271 and we're left with 247.
Take the next digit (7) from the dividend and append it to 247, then repeat: 2477 / 378

Let's proceed to step 8:
2477 divided by 378 is 6 with a remainder of 209.
The next digit of our result is 6. 
Result so far: 146186.0
The remainder is 209 after subtracting 2268 from 2477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
When dividing 2090 by 378, we get 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 146186.5
If we take 1890 away from 2090, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
The number 378 fits into 2000 5 times, leaving a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 146186.55
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 146186.55 with a remaining 0.11.
