We look at the division of 48225994 by 381 
The aim is to understand the frequency of 381 in 48225994.

Let's proceed to step 1:
4 divided by 381 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 381

Step 2:
381 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 381

Step 3:
If we divide 482 by 381, we get 1 and a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 381 from 482 leaves us with 101.
Append the next digit (2) from the dividend to 101 and continue with: 1012 / 381

Going ahead to step 4:
381 can be fit into 1012 2 times, resulting in a remainder of 250.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 762 from 1012, we get 250.
Bring next digit (5) of the dividend behind the 250 and repeat the process: 2505 / 381

Going ahead to step 5:
If we divide 2505 by 381, we get 6 and a remainder of 219.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtract 2286 from 2505 to get 219.
Fetch the next digit (9) from the dividend, attach it to 219 and continue: 2199 / 381

Step 6:
The number 381 fits into 2199 5 times, leaving a remainder of 294.
Use 5 as the next digit of our solution. 
Result so far: 1265.0
If we take 1905 away from 2199, we end up with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 381

Step 7:
The number 381 fits into 2949 7 times, leaving a remainder of 282.
The number 7 becomes the next digit in our result. 
Result so far: 12657.0
The remainder is 282 after subtracting 2667 from 2949.
Include the next digit (4) from the dividend after 282, then repeat: 2824 / 381

On to step 8:
The number 381 fits into 2824 7 times, leaving a remainder of 157.
Write down 7 as next digit of the result. 
Result so far: 126577.0
The remainder is 157 after subtracting 2667 from 2824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
If we divide 1570 by 381, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 126577.4
Deduct 1524 from 1570 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
The number 381 fits into 460 1 times, leaving a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 126577.41
Deduct 381 from 460 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
381 goes into 790 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 126577.412
Subtracting 762 from 790 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
The number 381 fits into 280 0 times, leaving a remainder of 280.
The next digit of our result is 0. 
Result so far: 126577.412
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
If we divide 2800 by 381, we get 7 and a remainder of 133.
The next digit of our result is 7. 
Result so far: 126577.41207
If we subtract 2667 from 2800, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 14:
381 can be fit into 1330 3 times, resulting in a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 126577.412073
Subtract 1143 from 1330 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 15:
381 goes into 1870 4 times with a remainder of 346.
Write down 4 as next digit of the result. 
Result so far: 126577.4120734
The remainder is 346 after subtracting 1524 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 16:
If we divide 3460 by 381, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 126577.41207349
If we subtract 3429 from 3460, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 126577.41207349, with a leftover of 3.1e-08.
