We look at the division of 62009649 by 381 
The aim is to understand the frequency of 381 in 62009649.

Going ahead to step 1:
The number 381 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 381

Advancing to step 2:
The number 381 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 381

Advancing to step 3:
620 divided by 381 is 1 with a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 381 from 620 leaves us with 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 381

Moving on to step 4:
381 can be fit into 2390 6 times, resulting in a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2286 from 2390, we get 104.
Grab the next digit (9) from the dividend, add it to 104, then carry on: 1049 / 381

Step 5:
When dividing 1049 by 381, we get 2 with a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 162.0
Subtracting 762 from 1049 leaves us with 287.
Include the next digit (6) from the dividend after 287, then repeat: 2876 / 381

Moving on to step 6:
The number 381 fits into 2876 7 times, leaving a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 1627.0
Subtracting 2667 from 2876 leaves us with 209.
Include the next digit (4) from the dividend after 209, then repeat: 2094 / 381

Going ahead to step 7:
2094 divided by 381 is 5 with a remainder of 189.
Write down 5 as next digit of the result. 
Result so far: 16275.0
If we take 1905 away from 2094, we end up with 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 381

Advancing to step 8:
If we divide 1899 by 381, we get 4 and a remainder of 375.
The next digit of our result is 4. 
Result so far: 162754.0
If we take 1524 away from 1899, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 9:
If we divide 3750 by 381, we get 9 and a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 162754.9
Subtracting 3429 from 3750 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 10:
If we divide 3210 by 381, we get 8 and a remainder of 162.
Record the quotient 8 as the next digit in the result. 
Result so far: 162754.98
If we take 3048 away from 3210, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 11:
When dividing 1620 by 381, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 162754.984
If we take 1524 away from 1620, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
381 can be fit into 960 2 times, resulting in a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 162754.9842
Subtracting 762 from 960 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 13:
381 goes into 1980 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 162754.98425
Subtracting 1905 from 1980 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
When dividing 750 by 381, we get 1 with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 162754.984251
If we subtract 381 from 750, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 15:
When dividing 3690 by 381, we get 9 with a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 162754.9842519
If we subtract 3429 from 3690, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 16:
When dividing 2610 by 381, we get 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 162754.98425196
If we subtract 2286 from 2610, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The quotient of the division is 162754.98425196, and the remainder is 3.24e-07.
