149233 divided by 21 
Let's see how many times 21 fits into 149233.

Step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Going ahead to step 2:
If we divide 14 by 21, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 21

Moving on to step 3:
When dividing 149 by 21, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 147 from 149 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

Let's proceed to step 4:
21 can be fit into 22 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 21 away from 22, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 21

Step 5:
21 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 710.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 21

Advancing to step 6:
When dividing 133 by 21, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 7106.0
Subtract 126 from 133 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.

Moving on to step 7:
21 can be fit into 70 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 7106.3
If we take 63 away from 70, we end up with 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 8:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 7106.33
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 7106.33 with a balance of 0.007.
