Let's divide 10021040 by 159
We want to divide 10021040 by 159.

On to step 1:
The number 159 fits into 1 0 times, leaving 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.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 159

Let's proceed to step 2:
The number 159 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 159

Advancing to step 3:
The number 159 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 100, we get 100.
Take the next digit (2) from the dividend and append it to 100, then repeat: 1002 / 159

On to step 4:
The number 159 fits into 1002 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 954 from 1002 to get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 159

On to step 5:
159 goes into 481 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 477 from 481 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 159

Going ahead to step 6:
40 divided by 159 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 630.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 159

Advancing to step 7:
When dividing 404 by 159, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 6302.0
If we take 318 away from 404, we end up with 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 159

Advancing to step 8:
159 can be fit into 860 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 63025.0
If we subtract 795 from 860, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
159 goes into 650 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 63025.4
Deduct 636 from 650 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 159, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 63025.4
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 159 is 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 63025.408
Deduct 1272 from 1400 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
159 goes into 1280 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 63025.4088
Deduct 1272 from 1280 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 63025.4088 with a balance of 8e-05.
