97974623 ÷ 386 
The aim is to understand the frequency of 386 in 97974623.

Advancing to step 1:
386 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 386

Moving on to step 2:
The number 386 fits into 97 0 times, leaving a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 386

Let's proceed to step 3:
If we divide 979 by 386, we get 2 and a remainder of 207.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 772 away from 979, we end up with 207.
Grab the next digit (7) from the dividend, add it to 207, then carry on: 2077 / 386

On to step 4:
2077 divided by 386 is 5 with a remainder of 147.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 1930 from 2077 leaves us with 147.
Append the next digit (4) from the dividend to 147 and continue with: 1474 / 386

Step 5:
If we divide 1474 by 386, we get 3 and a remainder of 316.
The next digit of our result is 3. 
Result so far: 253.0
Deduct 1158 from 1474 and we're left with 316.
Take the next digit (6) from the dividend and append it to 316, then repeat: 3166 / 386

On to step 6:
The number 386 fits into 3166 8 times, leaving a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 2538.0
Subtracting 3088 from 3166 leaves us with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 386

Let's proceed to step 7:
If we divide 782 by 386, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 25382.0
If we subtract 772 from 782, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 386

Advancing to step 8:
If we divide 103 by 386, we get 0 and a remainder of 103.
The next digit of our result is 0. 
Result so far: 253820.0
If we subtract 0 from 103, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 9:
1030 divided by 386 is 2 with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 253820.2
The remainder is 258 after subtracting 772 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
If we divide 2580 by 386, we get 6 and a remainder of 264.
The next digit of our result is 6. 
Result so far: 253820.26
The remainder is 264 after subtracting 2316 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
386 can be fit into 2640 6 times, resulting in a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 253820.266
If we subtract 2316 from 2640, 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.

After the division, we end up with 253820.266 and a remainder of 0.0324.
