We look at the division of 3316181 by 389 
The aim is to understand the frequency of 389 in 3316181.

Let's proceed to step 1:
389 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 389

Advancing to step 2:
389 can be fit into 33 0 times, resulting in a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 389

Step 3:
389 can be fit into 331 0 times, resulting in a remainder of 331.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 331 and we're left with 331.
Include the next digit (6) from the dividend after 331, then repeat: 3316 / 389

Advancing to step 4:
The number 389 fits into 3316 8 times, leaving a remainder of 204.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 3112 from 3316, we get 204.
Take the next digit (1) from the dividend and append it to 204, then repeat: 2041 / 389

Advancing to step 5:
If we divide 2041 by 389, we get 5 and a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 1945 away from 2041, we end up with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 389

Let's proceed to step 6:
When dividing 968 by 389, we get 2 with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 852.0
If we subtract 778 from 968, we get 190.
Grab the next digit (1) from the dividend, add it to 190, then carry on: 1901 / 389

Step 7:
1901 divided by 389 is 4 with a remainder of 345.
Write down 4 as next digit of the result. 
Result so far: 8524.0
Deduct 1556 from 1901 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 8:
If we divide 3450 by 389, we get 8 and a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 8524.8
If we take 3112 away from 3450, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 9:
The number 389 fits into 3380 8 times, leaving a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 8524.88
Deduct 3112 from 3380 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 8524.88, with a leftover of 0.268.
