Let's divide 25438373 by 386
The aim is to understand the frequency of 386 in 25438373.

Let's proceed to step 1:
386 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 386

On to step 2:
The number 386 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 386

Moving on to step 3:
254 divided by 386 is 0 with a remainder of 254.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 254, we end up with 254.
Append the next digit (3) from the dividend to 254 and continue with: 2543 / 386

Moving on to step 4:
If we divide 2543 by 386, we get 6 and a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2316 from 2543 and we're left with 227.
Bring next digit (8) of the dividend behind the 227 and repeat the process: 2278 / 386

Moving on to step 5:
When dividing 2278 by 386, we get 5 with a remainder of 348.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 1930 from 2278 to get 348.
Append the next digit (3) from the dividend to 348 and continue with: 3483 / 386

On to step 6:
386 can be fit into 3483 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
The remainder is 9 after subtracting 3474 from 3483.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 386

On to step 7:
97 divided by 386 is 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 6590.0
Subtract 0 from 97 to get 97.
Grab the next digit (3) from the dividend, add it to 97, then carry on: 973 / 386

Moving on to step 8:
973 divided by 386 is 2 with a remainder of 201.
The next digit of our result is 2. 
Result so far: 65902.0
Subtract 772 from 973 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 9:
386 goes into 2010 5 times with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 65902.5
If we subtract 1930 from 2010, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
386 can be fit into 800 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 65902.52
The remainder is 28 after subtracting 772 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 386 fits into 280 0 times, leaving a remainder of 280.
The next digit of our result is 0. 
Result so far: 65902.52
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
386 goes into 2800 7 times with a remainder of 98.
Use 7 as the next digit of our solution. 
Result so far: 65902.5207
Deduct 2702 from 2800 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 13:
386 can be fit into 980 2 times, resulting in a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 65902.52072
Subtract 772 from 980 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 14:
When dividing 2080 by 386, we get 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 65902.520725
Subtracting 1930 from 2080 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
When dividing 1500 by 386, we get 3 with a remainder of 342.
The next digit of our result is 3. 
Result so far: 65902.5207253
If we subtract 1158 from 1500, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 16:
386 can be fit into 3420 8 times, resulting in a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 65902.52072538
Deduct 3088 from 3420 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The quotient of the division is 65902.52072538, and the remainder is 3.32e-07.
