66313032 ÷ 159 
Our goal is to divide 66313032 by 159.

On to step 1:
The number 159 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 159

Going ahead to step 2:
The number 159 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 159

Moving on to step 3:
If we divide 663 by 159, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 636 from 663 and we're left with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 159

Step 4:
159 can be fit into 271 1 times, resulting in a remainder of 112.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtract 159 from 271 to get 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 159

Advancing to step 5:
The number 159 fits into 1123 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 417.0
Deduct 1113 from 1123 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 159

Moving on to step 6:
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: 4170.0
Deduct 0 from 100 and we're left with 100.
Bring next digit (3) of the dividend behind the 100 and repeat the process: 1003 / 159

On to step 7:
If we divide 1003 by 159, we get 6 and a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 41706.0
If we subtract 954 from 1003, we get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 159

Let's proceed to step 8:
When dividing 492 by 159, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 417063.0
Deduct 477 from 492 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 159 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 417063.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
159 goes into 1500 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 417063.09
Subtract 1431 from 1500 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
690 divided by 159 is 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 417063.094
Deduct 636 from 690 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
If we divide 540 by 159, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 417063.0943
Subtract 477 from 540 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 13:
159 goes into 630 3 times with a remainder of 153.
The next digit of our result is 3. 
Result so far: 417063.09433
Subtract 477 from 630 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

After the division, we end up with 417063.09433 and a remainder of 0.000153.
