We divide 18087577 by 221
We want to divide 18087577 by 221.

Let's proceed to step 1:
221 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 221

On to step 2:
221 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 221

Step 3:
221 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Include the next digit (8) from the dividend after 180, then repeat: 1808 / 221

Let's proceed to step 4:
1808 divided by 221 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 1768 from 1808 to get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 221

Going ahead to step 5:
407 divided by 221 is 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 221 from 407, we get 186.
Bring next digit (5) of the dividend behind the 186 and repeat the process: 1865 / 221

Moving on to step 6:
If we divide 1865 by 221, we get 8 and a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 818.0
Deduct 1768 from 1865 and we're left with 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 221

Let's proceed to step 7:
977 divided by 221 is 4 with a remainder of 93.
The next digit of our result is 4. 
Result so far: 8184.0
The remainder is 93 after subtracting 884 from 977.
Bring next digit (7) of the dividend behind the 93 and repeat the process: 937 / 221

On to step 8:
The number 221 fits into 937 4 times, leaving a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 81844.0
Deduct 884 from 937 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
If we divide 530 by 221, we get 2 and a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 81844.2
Subtracting 442 from 530 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
When dividing 880 by 221, we get 3 with a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 81844.23
If we subtract 663 from 880, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 11:
2170 divided by 221 is 9 with a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 81844.239
Subtracting 1989 from 2170 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 12:
221 goes into 1810 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 81844.2398
Deduct 1768 from 1810 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 221, we get 1 and a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 81844.23981
If we take 221 away from 420, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 14:
221 can be fit into 1990 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 81844.239819
Subtract 1989 from 1990 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 15:
10 divided by 221 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 81844.239819
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
221 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 81844.239819
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 81844.239819 with a balance of 1e-07.
