We're dividing 18137573 by 200 
We want to divide 18137573 by 200.

Advancing to step 1:
1 divided by 200 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 200

Going ahead to step 2:
When dividing 18 by 200, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 200

Moving on to step 3:
181 divided by 200 is 0 with a remainder of 181.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 181 to get 181.
Take the next digit (3) from the dividend and append it to 181, then repeat: 1813 / 200

Going ahead to step 4:
200 goes into 1813 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 1800 from 1813 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 200

Moving on to step 5:
200 can be fit into 137 0 times, resulting in a remainder of 137.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we subtract 0 from 137, we get 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 200

Let's proceed to step 6:
200 goes into 1375 6 times with a remainder of 175.
The number 6 becomes the next digit in our result. 
Result so far: 906.0
Subtract 1200 from 1375 to get 175.
Include the next digit (7) from the dividend after 175, then repeat: 1757 / 200

On to step 7:
If we divide 1757 by 200, we get 8 and a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 9068.0
If we subtract 1600 from 1757, we get 157.
Fetch the next digit (3) from the dividend, attach it to 157 and continue: 1573 / 200

Let's proceed to step 8:
1573 divided by 200 is 7 with a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 90687.0
Subtract 1400 from 1573 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 9:
200 goes into 1730 8 times with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 90687.8
The remainder is 130 after subtracting 1600 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
The number 200 fits into 1300 6 times, leaving a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 90687.86
Subtracting 1200 from 1300 leaves us 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.

Advancing to step 11:
When dividing 1000 by 200, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 90687.865
The remainder is 0 after subtracting 1000 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
200 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90687.865
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
When dividing 0 by 200, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90687.865
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 90687.865 with a remainder of 0.0.
