We're dividing 51321516 by 961 
We want to divide 51321516 by 961.

Advancing to step 1:
When dividing 5 by 961, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 961

Step 2:
961 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 961

Let's proceed to step 3:
The number 961 fits into 513 0 times, leaving a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 513, we get 513.
Append the next digit (2) from the dividend to 513 and continue with: 5132 / 961

Let's proceed to step 4:
The number 961 fits into 5132 5 times, leaving a remainder of 327.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4805 from 5132 and we're left with 327.
Take the next digit (1) from the dividend and append it to 327, then repeat: 3271 / 961

Let's proceed to step 5:
961 goes into 3271 3 times with a remainder of 388.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we subtract 2883 from 3271, we get 388.
Bring next digit (5) of the dividend behind the 388 and repeat the process: 3885 / 961

Let's proceed to step 6:
3885 divided by 961 is 4 with a remainder of 41.
The next digit of our result is 4. 
Result so far: 534.0
Deduct 3844 from 3885 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 961

Advancing to step 7:
If we divide 411 by 961, we get 0 and a remainder of 411.
The number 0 becomes the next digit in our result. 
Result so far: 5340.0
Subtracting 0 from 411 leaves us with 411.
Bring next digit (6) of the dividend behind the 411 and repeat the process: 4116 / 961

Going ahead to step 8:
961 goes into 4116 4 times with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 53404.0
If we subtract 3844 from 4116, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 9:
961 can be fit into 2720 2 times, resulting in a remainder of 798.
The number 2 becomes the next digit in our result. 
Result so far: 53404.2
If we take 1922 away from 2720, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Step 10:
The number 961 fits into 7980 8 times, leaving a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 53404.28
The remainder is 292 after subtracting 7688 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 11:
The number 961 fits into 2920 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 53404.283
The remainder is 37 after subtracting 2883 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 961, we get 0 and a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 53404.283
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 13:
3700 divided by 961 is 3 with a remainder of 817.
The next digit of our result is 3. 
Result so far: 53404.28303
Deduct 2883 from 3700 and we're left with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

On to step 14:
8170 divided by 961 is 8 with a remainder of 482.
Write down 8 as next digit of the result. 
Result so far: 53404.283038
If we take 7688 away from 8170, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 15:
If we divide 4820 by 961, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 53404.2830385
If we subtract 4805 from 4820, 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.

Step 16:
The number 961 fits into 150 0 times, leaving a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 53404.2830385
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.

In conclusion, the division gives 53404.2830385 with a balance of 1.5e-07.
