We're dividing 18371787 by 87 
Our goal is to divide 18371787 by 87.

Step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
The next digit of our result is 0. 
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 / 87

Step 2:
The number 87 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 87

Moving on to step 3:
The number 87 fits into 183 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 174 from 183 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 87

Moving on to step 4:
The number 87 fits into 97 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 87 away from 97, we end up with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 87

Let's proceed to step 5:
87 goes into 101 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
Deduct 87 from 101 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 87

Step 6:
If we divide 147 by 87, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 2111.0
Deduct 87 from 147 and we're left with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 87

Step 7:
87 can be fit into 608 6 times, resulting in a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 21116.0
Subtract 522 from 608 to get 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 87

On to step 8:
87 can be fit into 867 9 times, resulting in a remainder of 84.
The next digit of our result is 9. 
Result so far: 211169.0
If we subtract 783 from 867, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
87 goes into 840 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 211169.9
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
If we divide 570 by 87, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 211169.96
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
87 goes into 480 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 211169.965
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 211169.9655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 211169.9655 with a remainder of 0.00015.
