53054431 divided by 159 
We want to figure out the number of times 53054431 can be divided by 159.

Step 1:
If we divide 5 by 159, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 159

Step 2:
159 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 159

On to step 3:
The number 159 fits into 530 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 477 from 530, we get 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 159

Going ahead to step 4:
If we divide 535 by 159, we get 3 and a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 58 after subtracting 477 from 535.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 159

Step 5:
159 can be fit into 584 3 times, resulting in a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 333.0
The remainder is 107 after subtracting 477 from 584.
Take the next digit (4) from the dividend and append it to 107, then repeat: 1074 / 159

Let's proceed to step 6:
The number 159 fits into 1074 6 times, leaving a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 3336.0
Deduct 954 from 1074 and we're left with 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 159

On to step 7:
1203 divided by 159 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 33367.0
If we take 1113 away from 1203, we end up with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 159

Step 8:
If we divide 901 by 159, we get 5 and a remainder of 106.
Put 5 as the next digit of the answer. 
Result so far: 333675.0
If we subtract 795 from 901, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
If we divide 1060 by 159, we get 6 and a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 333675.6
Deduct 954 from 1060 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 10:
1060 divided by 159 is 6 with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 333675.66
Subtract 954 from 1060 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 333675.66 and a remainder of 0.106.
