We're dividing 21599653 by 150 
Let's see how many times 150 fits into 21599653.

Advancing to step 1:
2 divided by 150 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 150

Moving on to step 2:
150 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 150

Moving on to step 3:
150 can be fit into 215 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 150 from 215 and we're left with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 150

Let's proceed to step 4:
150 can be fit into 659 4 times, resulting in a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 59 after subtracting 600 from 659.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 150

Going ahead to step 5:
150 can be fit into 599 3 times, resulting in a remainder of 149.
Write down 3 as next digit of the result. 
Result so far: 143.0
The remainder is 149 after subtracting 450 from 599.
Take the next digit (6) from the dividend and append it to 149, then repeat: 1496 / 150

Advancing to step 6:
150 can be fit into 1496 9 times, resulting in a remainder of 146.
Use 9 as the next digit of our solution. 
Result so far: 1439.0
If we take 1350 away from 1496, we end up with 146.
Grab the next digit (5) from the dividend, add it to 146, then carry on: 1465 / 150

On to step 7:
The number 150 fits into 1465 9 times, leaving a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 14399.0
Subtract 1350 from 1465 to get 115.
Bring next digit (3) of the dividend behind the 115 and repeat the process: 1153 / 150

Advancing to step 8:
1153 divided by 150 is 7 with a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 143997.0
The remainder is 103 after subtracting 1050 from 1153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
150 can be fit into 1030 6 times, resulting in a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 143997.6
Deduct 900 from 1030 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
150 goes into 1300 8 times with a remainder of 100.
The next digit of our result is 8. 
Result so far: 143997.68
Subtracting 1200 from 1300 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
150 goes into 1000 6 times with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 143997.686
Subtract 900 from 1000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
1000 divided by 150 is 6 with a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 143997.6866
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 143997.6866, and the remainder is 0.001.
