Let's divide 156492 by 21
Let's see how many times 21 fits into 156492.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 21

Let's proceed to step 2:
When dividing 15 by 21, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 21

On to step 3:
The number 21 fits into 156 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 147 from 156, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 21

Let's proceed to step 4:
21 goes into 94 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 84 from 94 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 21

Going ahead to step 5:
The number 21 fits into 109 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
The remainder is 4 after subtracting 105 from 109.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 21

Going ahead to step 6:
When dividing 42 by 21, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 7452.0
If we subtract 42 from 42, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
21 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7452.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7452.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7452.0, with a leftover of 0.0.
