We divide 186235 by 21
Let's see how many times 21 fits into 186235.

Let's proceed to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 21

Advancing to step 2:
18 divided by 21 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Let's proceed to step 3:
21 can be fit into 186 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 18 after subtracting 168 from 186.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 21

Let's proceed to step 4:
The number 21 fits into 182 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 88.0
If we subtract 168 from 182, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 21

Going ahead to step 5:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 886.0
Subtract 126 from 143 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 21

Going ahead to step 6:
When dividing 175 by 21, we get 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8868.0
Subtract 168 from 175 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 21 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8868.3
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 8868.33
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 8868.33 and a remainder of 0.007.
