212188 ÷ 86 
The aim is to understand the frequency of 86 in 212188.

Going ahead to step 1:
86 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 86

Moving on to step 2:
21 divided by 86 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 86

Step 3:
86 can be fit into 212 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 40 after subtracting 172 from 212.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 86

Step 4:
The number 86 fits into 401 4 times, leaving a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 57 after subtracting 344 from 401.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 86

Advancing to step 5:
If we divide 578 by 86, we get 6 and a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Subtracting 516 from 578 leaves us with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 86

Let's proceed to step 6:
The number 86 fits into 628 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 2467.0
Subtract 602 from 628 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.

Step 7:
When dividing 260 by 86, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2467.3
Subtracting 258 from 260 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.

Step 8:
86 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2467.3
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.

Advancing to step 9:
When dividing 200 by 86, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2467.302
Deduct 172 from 200 and we're left 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.

Moving on to step 10:
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: 2467.3023
The remainder is 22 after subtracting 258 from 280.
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 11:
220 divided by 86 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2467.30232
Subtracting 172 from 220 leaves us 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.

Step 12:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 2467.302325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
500 divided by 86 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 2467.3023255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 2467.3023255, and the remainder is 7e-07.
