18086550 ÷ 197 
We're looking to find how many times 197 goes into 18086550.

Step 1:
197 goes into 1 0 times 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.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 197

Let's proceed to step 2:
When dividing 18 by 197, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 197

Let's proceed to step 3:
When dividing 180 by 197, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 180 and we're left with 180.
Take the next digit (8) from the dividend and append it to 180, then repeat: 1808 / 197

Advancing to step 4:
If we divide 1808 by 197, we get 9 and a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 1773 from 1808 leaves us with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 197

Let's proceed to step 5:
197 goes into 356 1 times with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 159 after subtracting 197 from 356.
Include the next digit (5) from the dividend after 159, then repeat: 1595 / 197

Moving on to step 6:
197 can be fit into 1595 8 times, resulting in a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 918.0
If we take 1576 away from 1595, we end up with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 197

Going ahead to step 7:
197 goes into 195 0 times with a remainder of 195.
The next digit of our result is 0. 
Result so far: 9180.0
Deduct 0 from 195 and we're left with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 197

Let's proceed to step 8:
When dividing 1950 by 197, we get 9 with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 91809.0
The remainder is 177 after subtracting 1773 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
When dividing 1770 by 197, we get 8 with a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 91809.8
If we subtract 1576 from 1770, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 10:
If we divide 1940 by 197, we get 9 and a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 91809.89
If we subtract 1773 from 1940, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 11:
197 can be fit into 1670 8 times, resulting in a remainder of 94.
The next digit of our result is 8. 
Result so far: 91809.898
Subtracting 1576 from 1670 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.

Advancing to step 12:
The number 197 fits into 940 4 times, leaving a remainder of 152.
The next digit of our result is 4. 
Result so far: 91809.8984
Subtract 788 from 940 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
If we divide 1520 by 197, we get 7 and a remainder of 141.
The next digit of our result is 7. 
Result so far: 91809.89847
Subtract 1379 from 1520 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 14:
When dividing 1410 by 197, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 91809.898477
Subtracting 1379 from 1410 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 91809.898477 with a remaining 3.1e-06.
