Let's divide 71318993 by 385
The aim is to understand the frequency of 385 in 71318993.

Step 1:
When dividing 7 by 385, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 385

Moving on to step 2:
385 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 385

Step 3:
If we divide 713 by 385, we get 1 and a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 385 from 713 to get 328.
Append the next digit (1) from the dividend to 328 and continue with: 3281 / 385

Step 4:
When dividing 3281 by 385, we get 8 with a remainder of 201.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 3080 away from 3281, we end up with 201.
Grab the next digit (8) from the dividend, add it to 201, then carry on: 2018 / 385

Advancing to step 5:
385 can be fit into 2018 5 times, resulting in a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Subtracting 1925 from 2018 leaves us with 93.
Take the next digit (9) from the dividend and append it to 93, then repeat: 939 / 385

Moving on to step 6:
385 can be fit into 939 2 times, resulting in a remainder of 169.
Use 2 as the next digit of our solution. 
Result so far: 1852.0
If we take 770 away from 939, we end up with 169.
Fetch the next digit (9) from the dividend, attach it to 169 and continue: 1699 / 385

Advancing to step 7:
When dividing 1699 by 385, we get 4 with a remainder of 159.
Use 4 as the next digit of our solution. 
Result so far: 18524.0
Subtracting 1540 from 1699 leaves us with 159.
Bring next digit (3) of the dividend behind the 159 and repeat the process: 1593 / 385

Moving on to step 8:
When dividing 1593 by 385, we get 4 with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 185244.0
Subtracting 1540 from 1593 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
The number 385 fits into 530 1 times, leaving a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 185244.1
If we subtract 385 from 530, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
1450 divided by 385 is 3 with a remainder of 295.
Use 3 as the next digit of our solution. 
Result so far: 185244.13
If we subtract 1155 from 1450, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 11:
If we divide 2950 by 385, we get 7 and a remainder of 255.
The next digit of our result is 7. 
Result so far: 185244.137
If we take 2695 away from 2950, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 12:
When dividing 2550 by 385, we get 6 with a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 185244.1376
Subtracting 2310 from 2550 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
If we divide 2400 by 385, we get 6 and a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 185244.13766
If we take 2310 away from 2400, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 185244.13766, with a leftover of 9e-05.
