We look at the division of 20902487 by 187 
We're looking to find how many times 187 goes into 20902487.

Let's proceed to step 1:
2 divided by 187 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 187

On to step 2:
When dividing 20 by 187, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 187

On to step 3:
187 goes into 209 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 187 from 209 leaves us with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 187

Moving on to step 4:
The number 187 fits into 220 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 187 from 220 leaves us with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 187

Let's proceed to step 5:
The number 187 fits into 332 1 times, leaving a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 111.0
If we subtract 187 from 332, we get 145.
Take the next digit (4) from the dividend and append it to 145, then repeat: 1454 / 187

Moving on to step 6:
When dividing 1454 by 187, we get 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 1117.0
Subtracting 1309 from 1454 leaves us with 145.
Append the next digit (8) from the dividend to 145 and continue with: 1458 / 187

Going ahead to step 7:
The number 187 fits into 1458 7 times, leaving a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 11177.0
Subtract 1309 from 1458 to get 149.
Include the next digit (7) from the dividend after 149, then repeat: 1497 / 187

Moving on to step 8:
When dividing 1497 by 187, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 111778.0
Deduct 1496 from 1497 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
187 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 111778.0
If we subtract 0 from 10, we 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.

On to step 10:
The number 187 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 111778.0
Deduct 0 from 100 and we're left 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.

After the division, we end up with 111778.0 and a remainder of 0.1.
