Let's divide 51435159 by 965
We want to divide 51435159 by 965.

Advancing to step 1:
When dividing 5 by 965, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 965

Step 2:
965 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 965

Let's proceed to step 3:
When dividing 514 by 965, we get 0 with a remainder of 514.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 514 and we're left with 514.
Take the next digit (3) from the dividend and append it to 514, then repeat: 5143 / 965

Advancing to step 4:
965 can be fit into 5143 5 times, resulting in a remainder of 318.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4825 from 5143, we get 318.
Fetch the next digit (5) from the dividend, attach it to 318 and continue: 3185 / 965

Advancing to step 5:
965 goes into 3185 3 times with a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 290 after subtracting 2895 from 3185.
Grab the next digit (1) from the dividend, add it to 290, then carry on: 2901 / 965

On to step 6:
965 goes into 2901 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 533.0
Subtracting 2895 from 2901 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 965

Moving on to step 7:
The number 965 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 5330.0
The remainder is 65 after subtracting 0 from 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 965

On to step 8:
965 can be fit into 659 0 times, resulting in a remainder of 659.
Use 0 as the next digit of our solution. 
Result so far: 53300.0
Subtract 0 from 659 to get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

On to step 9:
965 goes into 6590 6 times with a remainder of 800.
The next digit of our result is 6. 
Result so far: 53300.6
Deduct 5790 from 6590 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 10:
When dividing 8000 by 965, we get 8 with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 53300.68
Deduct 7720 from 8000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
The number 965 fits into 2800 2 times, leaving a remainder of 870.
Put 2 as the next digit of the answer. 
Result so far: 53300.682
If we take 1930 away from 2800, we end up with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Advancing to step 12:
The number 965 fits into 8700 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 53300.6829
If we subtract 8685 from 8700, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
965 goes into 150 0 times with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 53300.6829
If we take 0 away from 150, we end up 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.

Let's proceed to step 14:
If we divide 1500 by 965, we get 1 and a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 53300.682901
Deduct 965 from 1500 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 15:
5350 divided by 965 is 5 with a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 53300.6829015
The remainder is 525 after subtracting 4825 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 16:
When dividing 5250 by 965, we get 5 with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 53300.68290155
Subtracting 4825 from 5250 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final result is 53300.68290155 with a remainder of 4.25e-07.
