Let's divide 51350589 by 144
We want to divide 51350589 by 144.

Step 1:
When dividing 5 by 144, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 144

Moving on to step 2:
When dividing 51 by 144, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 144

Advancing to step 3:
144 goes into 513 3 times with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 432 from 513 to get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 144

On to step 4:
If we divide 815 by 144, we get 5 and a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 95 after subtracting 720 from 815.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 144

On to step 5:
The number 144 fits into 950 6 times, leaving a remainder of 86.
The next digit of our result is 6. 
Result so far: 356.0
The remainder is 86 after subtracting 864 from 950.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 144

Going ahead to step 6:
When dividing 865 by 144, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3566.0
If we subtract 864 from 865, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 144

Moving on to step 7:
If we divide 18 by 144, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 35660.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 144

Going ahead to step 8:
If we divide 189 by 144, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 356601.0
The remainder is 45 after subtracting 144 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
The number 144 fits into 450 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 356601.3
Deduct 432 from 450 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
144 goes into 180 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 356601.31
If we subtract 144 from 180, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 144 fits into 360 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 356601.312
The remainder is 72 after subtracting 288 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
When dividing 720 by 144, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 356601.3125
If we take 720 away from 720, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
144 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 356601.3125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
144 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 356601.3125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 356601.3125 with a remainder of 0.0.
