18836099 ÷ 217 
We want to divide 18836099 by 217.

Let's proceed to step 1:
When dividing 1 by 217, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 217

Moving on to step 2:
The number 217 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 217

Going ahead to step 3:
If we divide 188 by 217, we get 0 and a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 188, we get 188.
Take the next digit (3) from the dividend and append it to 188, then repeat: 1883 / 217

Going ahead to step 4:
The number 217 fits into 1883 8 times, leaving a remainder of 147.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 1736 away from 1883, we end up with 147.
Fetch the next digit (6) from the dividend, attach it to 147 and continue: 1476 / 217

Step 5:
1476 divided by 217 is 6 with a remainder of 174.
The next digit of our result is 6. 
Result so far: 86.0
If we take 1302 away from 1476, we end up with 174.
Include the next digit (0) from the dividend after 174, then repeat: 1740 / 217

Step 6:
When dividing 1740 by 217, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 868.0
Deduct 1736 from 1740 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 217

Step 7:
217 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 8680.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 217

Advancing to step 8:
If we divide 499 by 217, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 86802.0
Deduct 434 from 499 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
217 can be fit into 650 2 times, resulting in a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 86802.2
If we subtract 434 from 650, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
217 goes into 2160 9 times with a remainder of 207.
The number 9 becomes the next digit in our result. 
Result so far: 86802.29
Subtracting 1953 from 2160 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 11:
When dividing 2070 by 217, we get 9 with a remainder of 117.
Record the quotient 9 as the next digit in the result. 
Result so far: 86802.299
If we subtract 1953 from 2070, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final outcome is 86802.299, with a leftover of 0.0117.
