21906506 ÷ 150 
We're looking to find how many times 150 goes into 21906506.

On to step 1:
The number 150 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 150

Moving on to step 2:
When dividing 21 by 150, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 150

Advancing to step 3:
The number 150 fits into 219 1 times, leaving a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 150 from 219 leaves us with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 150

Step 4:
The number 150 fits into 690 4 times, leaving a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 600 from 690 to get 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 150

Advancing to step 5:
When dividing 906 by 150, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 900 from 906 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 150

On to step 6:
150 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 1460.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 150

Step 7:
150 can be fit into 650 4 times, resulting in a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 14604.0
Deduct 600 from 650 and we're left with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 150

Let's proceed to step 8:
When dividing 506 by 150, we get 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 146043.0
Subtracting 450 from 506 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 150 is 3 with a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 146043.3
If we subtract 450 from 560, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
The number 150 fits into 1100 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 146043.37
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 150, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 146043.373
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 150 fits into 500 3 times, leaving a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 146043.3733
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 146043.3733 with a remainder of 0.0005.
