Let's divide 91813867 by 186
The aim is to understand the frequency of 186 in 91813867.

On to step 1:
If we divide 9 by 186, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 186

Advancing to step 2:
The number 186 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 186

Let's proceed to step 3:
The number 186 fits into 918 4 times, leaving a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 744 from 918 to get 174.
Include the next digit (1) from the dividend after 174, then repeat: 1741 / 186

Step 4:
186 goes into 1741 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we take 1674 away from 1741, we end up with 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 186

On to step 5:
If we divide 673 by 186, we get 3 and a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 493.0
If we take 558 away from 673, we end up with 115.
Include the next digit (8) from the dividend after 115, then repeat: 1158 / 186

Let's proceed to step 6:
186 can be fit into 1158 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 4936.0
Subtract 1116 from 1158 to get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 186

Going ahead to step 7:
186 can be fit into 426 2 times, resulting in a remainder of 54.
The next digit of our result is 2. 
Result so far: 49362.0
Subtracting 372 from 426 leaves us with 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 186

On to step 8:
186 can be fit into 547 2 times, resulting in a remainder of 175.
Write down 2 as next digit of the result. 
Result so far: 493622.0
The remainder is 175 after subtracting 372 from 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 9:
1750 divided by 186 is 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 493622.9
If we take 1674 away from 1750, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
The number 186 fits into 760 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 493622.94
Subtracting 744 from 760 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 186, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 493622.94
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
186 can be fit into 1600 8 times, resulting in a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 493622.9408
Subtracting 1488 from 1600 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
The number 186 fits into 1120 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 493622.94086
The remainder is 4 after subtracting 1116 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
40 divided by 186 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 493622.94086
Deduct 0 from 40 and we're left 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.

On to step 15:
186 can be fit into 400 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 493622.9408602
The remainder is 28 after subtracting 372 from 400.
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 16:
186 goes into 280 1 times with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 493622.94086021
Subtracting 186 from 280 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final outcome is 493622.94086021, with a leftover of 9.4e-08.
