Let's divide 198138 by 86
The aim is to understand the frequency of 86 in 198138.

Advancing to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 86

Step 2:
When dividing 19 by 86, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 86

Let's proceed to step 3:
86 can be fit into 198 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 172 from 198, we get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 86

On to step 4:
The number 86 fits into 261 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 3 after subtracting 258 from 261.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 86

On to step 5:
If we divide 33 by 86, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 86

Moving on to step 6:
The number 86 fits into 338 3 times, leaving a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 2303.0
If we subtract 258 from 338, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
If we divide 800 by 86, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 2303.9
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
86 goes into 260 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 2303.93
If we take 258 away from 260, we end up 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.

Step 9:
The number 86 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 2303.93
If we take 0 away from 20, we end up 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.

Step 10:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 2303.9302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 86, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 2303.93023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
86 can be fit into 220 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 2303.930232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
The number 86 fits into 480 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2303.9302325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 86 fits into 500 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 2303.93023255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 2303.93023255, with a leftover of 7e-08.
