188172 ÷ 86 
The aim is to understand the frequency of 86 in 188172.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 86

Let's proceed to step 2:
The number 86 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 86

On to step 3:
If we divide 188 by 86, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 172 from 188 and we're left with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 86

Let's proceed to step 4:
161 divided by 86 is 1 with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 86 from 161 and we're left with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 86

Step 5:
757 divided by 86 is 8 with a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
If we subtract 688 from 757, we get 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 86

Going ahead to step 6:
86 goes into 692 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 2188.0
If we subtract 688 from 692, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2188.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
86 can be fit into 400 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 2188.04
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
When dividing 560 by 86, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2188.046
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 86, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2188.0465
Deduct 430 from 440 and we're left 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.

On to step 11:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 2188.04651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 2188.046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 2188.046511, with a leftover of 5.4e-06.
