16518845 ÷ 186 
The aim is to understand the frequency of 186 in 16518845.

Let's proceed to step 1:
If we divide 1 by 186, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 186

On to step 2:
If we divide 16 by 186, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 186

Advancing to step 3:
186 can be fit into 165 0 times, resulting in a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 165 to get 165.
Fetch the next digit (1) from the dividend, attach it to 165 and continue: 1651 / 186

Let's proceed to step 4:
186 can be fit into 1651 8 times, resulting in a remainder of 163.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 1488 from 1651 to get 163.
Fetch the next digit (8) from the dividend, attach it to 163 and continue: 1638 / 186

Moving on to step 5:
If we divide 1638 by 186, we get 8 and a remainder of 150.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 1488 away from 1638, we end up with 150.
Fetch the next digit (8) from the dividend, attach it to 150 and continue: 1508 / 186

On to step 6:
186 goes into 1508 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 888.0
If we take 1488 away from 1508, we end up with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 186

On to step 7:
When dividing 204 by 186, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 8881.0
Subtracting 186 from 204 leaves us with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 186

On to step 8:
186 goes into 185 0 times with a remainder of 185.
Use 0 as the next digit of our solution. 
Result so far: 88810.0
Deduct 0 from 185 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 9:
186 can be fit into 1850 9 times, resulting in a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 88810.9
If we subtract 1674 from 1850, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
When dividing 1760 by 186, we get 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 88810.99
The remainder is 86 after subtracting 1674 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 88810.99, and the remainder is 0.086.
