11858 divided by 38 
The aim is to understand the frequency of 38 in 11858.

On to step 1:
When dividing 1 by 38, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 38

Let's proceed to step 2:
When dividing 11 by 38, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 38

Moving on to step 3:
When dividing 118 by 38, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 114 from 118 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 38

Moving on to step 4:
45 divided by 38 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 38 from 45 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 38

On to step 5:
When dividing 78 by 38, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 312.0
Subtracting 76 from 78 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
When dividing 20 by 38, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 312.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
38 goes into 200 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 312.05
Subtracting 190 from 200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
38 can be fit into 100 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 312.052
If we subtract 76 from 100, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 38, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 312.0526
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 38, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 312.05263
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
If we divide 60 by 38, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 312.052631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
When dividing 220 by 38, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 312.0526315
Subtracting 190 from 220 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 312.05263157
If we take 266 away from 300, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 312.05263157 with a remainder of 3.4e-08.
