We're dividing 42088362 by 389 
The aim is to understand the frequency of 389 in 42088362.

On to step 1:
The number 389 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 389

Let's proceed to step 2:
42 divided by 389 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 389

Step 3:
The number 389 fits into 420 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 31 after subtracting 389 from 420.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 389

Going ahead to step 4:
389 can be fit into 318 0 times, resulting in a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 318, we end up with 318.
Bring next digit (8) of the dividend behind the 318 and repeat the process: 3188 / 389

Going ahead to step 5:
3188 divided by 389 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 3112 away from 3188, we end up with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 389

Going ahead to step 6:
389 can be fit into 763 1 times, resulting in a remainder of 374.
Record the quotient 1 as the next digit in the result. 
Result so far: 1081.0
If we subtract 389 from 763, we get 374.
Append the next digit (6) from the dividend to 374 and continue with: 3746 / 389

Moving on to step 7:
389 goes into 3746 9 times with a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 10819.0
Subtract 3501 from 3746 to get 245.
Bring next digit (2) of the dividend behind the 245 and repeat the process: 2452 / 389

Moving on to step 8:
When dividing 2452 by 389, we get 6 with a remainder of 118.
Record the quotient 6 as the next digit in the result. 
Result so far: 108196.0
If we take 2334 away from 2452, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
1180 divided by 389 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 108196.3
Deduct 1167 from 1180 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 389 fits into 130 0 times, leaving a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 108196.3
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
1300 divided by 389 is 3 with a remainder of 133.
Put 3 as the next digit of the answer. 
Result so far: 108196.303
Subtracting 1167 from 1300 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
The number 389 fits into 1330 3 times, leaving a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 108196.3033
Subtract 1167 from 1330 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

The final result is 108196.3033 with a remainder of 0.00163.
