3180685 divided by 381 
The aim is to understand the frequency of 381 in 3180685.

Going ahead to step 1:
381 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 381

Let's proceed to step 2:
381 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 381

Going ahead to step 3:
318 divided by 381 is 0 with a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 318 to get 318.
Fetch the next digit (0) from the dividend, attach it to 318 and continue: 3180 / 381

Going ahead to step 4:
3180 divided by 381 is 8 with a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3048 from 3180 leaves us with 132.
Bring next digit (6) of the dividend behind the 132 and repeat the process: 1326 / 381

Moving on to step 5:
381 goes into 1326 3 times with a remainder of 183.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 183 after subtracting 1143 from 1326.
Include the next digit (8) from the dividend after 183, then repeat: 1838 / 381

Going ahead to step 6:
The number 381 fits into 1838 4 times, leaving a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 834.0
Deduct 1524 from 1838 and we're left with 314.
Include the next digit (5) from the dividend after 314, then repeat: 3145 / 381

Going ahead to step 7:
381 goes into 3145 8 times with a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 8348.0
If we subtract 3048 from 3145, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 8:
The number 381 fits into 970 2 times, leaving a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 8348.2
The remainder is 208 after subtracting 762 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 9:
If we divide 2080 by 381, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 8348.25
Subtracting 1905 from 2080 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
381 can be fit into 1750 4 times, resulting in a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 8348.254
Subtract 1524 from 1750 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 11:
If we divide 2260 by 381, we get 5 and a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 8348.2545
Subtract 1905 from 2260 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 12:
When dividing 3550 by 381, we get 9 with a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 8348.25459
Subtract 3429 from 3550 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 13:
1210 divided by 381 is 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 8348.254593
The remainder is 67 after subtracting 1143 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
When dividing 670 by 381, we get 1 with a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 8348.2545931
Subtract 381 from 670 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 15:
The number 381 fits into 2890 7 times, leaving a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 8348.25459317
The remainder is 223 after subtracting 2667 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Our division results in 8348.25459317 with a remaining 2.23e-07.
