We look at the division of 21896540 by 186 
Let's see how many times 186 fits into 21896540.

Let's proceed to step 1:
If we divide 2 by 186, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 186

Step 2:
21 divided by 186 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 186

Moving on to step 3:
186 goes into 218 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 186 from 218 and we're left with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 186

Moving on to step 4:
The number 186 fits into 329 1 times, leaving a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 143 after subtracting 186 from 329.
Include the next digit (6) from the dividend after 143, then repeat: 1436 / 186

Step 5:
If we divide 1436 by 186, we get 7 and a remainder of 134.
The next digit of our result is 7. 
Result so far: 117.0
The remainder is 134 after subtracting 1302 from 1436.
Include the next digit (5) from the dividend after 134, then repeat: 1345 / 186

Advancing to step 6:
The number 186 fits into 1345 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 1177.0
If we take 1302 away from 1345, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 186

Step 7:
The number 186 fits into 434 2 times, leaving a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 11772.0
The remainder is 62 after subtracting 372 from 434.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 186

Advancing to step 8:
186 can be fit into 620 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 117723.0
Deduct 558 from 620 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
When dividing 620 by 186, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 117723.3
If we subtract 558 from 620, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
186 can be fit into 620 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 117723.33
If we subtract 558 from 620, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 117723.33 and a remainder of 0.062.
