We're dividing 18439316 by 381 
The aim is to understand the frequency of 381 in 18439316.

Going ahead to step 1:
If we divide 1 by 381, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 381

Going ahead to step 2:
When dividing 18 by 381, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 381

Going ahead to step 3:
184 divided by 381 is 0 with a remainder of 184.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 381

Going ahead to step 4:
When dividing 1843 by 381, we get 4 with a remainder of 319.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1524 from 1843 and we're left with 319.
Bring next digit (9) of the dividend behind the 319 and repeat the process: 3199 / 381

On to step 5:
When dividing 3199 by 381, we get 8 with a remainder of 151.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 3048 away from 3199, we end up with 151.
Fetch the next digit (3) from the dividend, attach it to 151 and continue: 1513 / 381

Advancing to step 6:
When dividing 1513 by 381, we get 3 with a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 483.0
Deduct 1143 from 1513 and we're left with 370.
Bring next digit (1) of the dividend behind the 370 and repeat the process: 3701 / 381

Let's proceed to step 7:
381 goes into 3701 9 times with a remainder of 272.
Record the quotient 9 as the next digit in the result. 
Result so far: 4839.0
Subtracting 3429 from 3701 leaves us with 272.
Include the next digit (6) from the dividend after 272, then repeat: 2726 / 381

Moving on to step 8:
The number 381 fits into 2726 7 times, leaving a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 48397.0
Subtract 2667 from 2726 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
381 can be fit into 590 1 times, resulting in a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 48397.1
Deduct 381 from 590 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 10:
When dividing 2090 by 381, we get 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 48397.15
The remainder is 185 after subtracting 1905 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
381 can be fit into 1850 4 times, resulting in a remainder of 326.
Put 4 as the next digit of the answer. 
Result so far: 48397.154
Deduct 1524 from 1850 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 12:
If we divide 3260 by 381, we get 8 and a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 48397.1548
Subtract 3048 from 3260 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 13:
381 goes into 2120 5 times with a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 48397.15485
The remainder is 215 after subtracting 1905 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 14:
When dividing 2150 by 381, we get 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 48397.154855
Subtract 1905 from 2150 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final result is 48397.154855 with a remainder of 2.45e-05.
