We're dividing 70242904 by 386 
The aim is to understand the frequency of 386 in 70242904.

On to step 1:
7 divided by 386 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 386

Going ahead to step 2:
386 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 386

Step 3:
386 can be fit into 702 1 times, resulting in a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 386 from 702, we get 316.
Append the next digit (4) from the dividend to 316 and continue with: 3164 / 386

On to step 4:
3164 divided by 386 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 76 after subtracting 3088 from 3164.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 386

Step 5:
When dividing 762 by 386, we get 1 with a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Subtracting 386 from 762 leaves us with 376.
Include the next digit (9) from the dividend after 376, then repeat: 3769 / 386

Going ahead to step 6:
3769 divided by 386 is 9 with a remainder of 295.
The next digit of our result is 9. 
Result so far: 1819.0
If we subtract 3474 from 3769, we get 295.
Append the next digit (0) from the dividend to 295 and continue with: 2950 / 386

Let's proceed to step 7:
The number 386 fits into 2950 7 times, leaving a remainder of 248.
Put 7 as the next digit of the answer. 
Result so far: 18197.0
Subtract 2702 from 2950 to get 248.
Include the next digit (4) from the dividend after 248, then repeat: 2484 / 386

Let's proceed to step 8:
386 can be fit into 2484 6 times, resulting in a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 181976.0
If we take 2316 away from 2484, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 9:
When dividing 1680 by 386, we get 4 with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 181976.4
The remainder is 136 after subtracting 1544 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
386 can be fit into 1360 3 times, resulting in a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 181976.43
Deduct 1158 from 1360 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 11:
386 can be fit into 2020 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 181976.435
The remainder is 90 after subtracting 1930 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
If we divide 900 by 386, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 181976.4352
If we subtract 772 from 900, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
The number 386 fits into 1280 3 times, leaving a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 181976.43523
If we take 1158 away from 1280, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 14:
386 goes into 1220 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 181976.435233
Deduct 1158 from 1220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 181976.435233 with a remainder of 6.2e-06.
