We look at the division of 6388429 by 150 
We want to figure out the number of times 6388429 can be divided by 150.

Advancing to step 1:
150 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 150

Moving on to step 2:
The number 150 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 150

Step 3:
150 can be fit into 638 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 600 away from 638, we end up with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 150

Going ahead to step 4:
The number 150 fits into 388 2 times, leaving a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 300 away from 388, we end up with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 150

Going ahead to step 5:
150 can be fit into 884 5 times, resulting in a remainder of 134.
Put 5 as the next digit of the answer. 
Result so far: 425.0
Subtract 750 from 884 to get 134.
Take the next digit (2) from the dividend and append it to 134, then repeat: 1342 / 150

On to step 6:
150 can be fit into 1342 8 times, resulting in a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 4258.0
If we subtract 1200 from 1342, we get 142.
Fetch the next digit (9) from the dividend, attach it to 142 and continue: 1429 / 150

Moving on to step 7:
When dividing 1429 by 150, we get 9 with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 42589.0
If we subtract 1350 from 1429, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 8:
150 can be fit into 790 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 42589.5
If we take 750 away from 790, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
If we divide 400 by 150, we get 2 and a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 42589.52
If we take 300 away from 400, we end up 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.

Step 10:
If we divide 1000 by 150, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 42589.526
If we subtract 900 from 1000, we 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.

On to step 11:
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: 42589.5266
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 42589.5266, and the remainder is 0.001.
