We're dividing 28521257 by 961 
We want to divide 28521257 by 961.

Let's proceed to step 1:
When dividing 2 by 961, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 961

Advancing to step 2:
If we divide 28 by 961, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 961

Moving on to step 3:
The number 961 fits into 285 0 times, leaving a remainder of 285.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 285 after subtracting 0 from 285.
Append the next digit (2) from the dividend to 285 and continue with: 2852 / 961

Moving on to step 4:
If we divide 2852 by 961, we get 2 and a remainder of 930.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1922 from 2852 to get 930.
Include the next digit (1) from the dividend after 930, then repeat: 9301 / 961

Moving on to step 5:
9301 divided by 961 is 9 with a remainder of 652.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 8649 from 9301 and we're left with 652.
Bring next digit (2) of the dividend behind the 652 and repeat the process: 6522 / 961

Let's proceed to step 6:
961 goes into 6522 6 times with a remainder of 756.
Put 6 as the next digit of the answer. 
Result so far: 296.0
If we take 5766 away from 6522, we end up with 756.
Grab the next digit (5) from the dividend, add it to 756, then carry on: 7565 / 961

Advancing to step 7:
The number 961 fits into 7565 7 times, leaving a remainder of 838.
The number 7 becomes the next digit in our result. 
Result so far: 2967.0
The remainder is 838 after subtracting 6727 from 7565.
Append the next digit (7) from the dividend to 838 and continue with: 8387 / 961

Step 8:
8387 divided by 961 is 8 with a remainder of 699.
Write down 8 as next digit of the result. 
Result so far: 29678.0
The remainder is 699 after subtracting 7688 from 8387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

On to step 9:
6990 divided by 961 is 7 with a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 29678.7
Deduct 6727 from 6990 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 10:
The number 961 fits into 2630 2 times, leaving a remainder of 708.
Use 2 as the next digit of our solution. 
Result so far: 29678.72
Subtract 1922 from 2630 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 11:
When dividing 7080 by 961, we get 7 with a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 29678.727
If we subtract 6727 from 7080, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 12:
When dividing 3530 by 961, we get 3 with a remainder of 647.
Put 3 as the next digit of the answer. 
Result so far: 29678.7273
The remainder is 647 after subtracting 2883 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Moving on to step 13:
The number 961 fits into 6470 6 times, leaving a remainder of 704.
The number 6 becomes the next digit in our result. 
Result so far: 29678.72736
The remainder is 704 after subtracting 5766 from 6470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 14:
If we divide 7040 by 961, we get 7 and a remainder of 313.
The number 7 becomes the next digit in our result. 
Result so far: 29678.727367
Deduct 6727 from 7040 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 15:
The number 961 fits into 3130 3 times, leaving a remainder of 247.
Use 3 as the next digit of our solution. 
Result so far: 29678.7273673
If we subtract 2883 from 3130, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 16:
961 can be fit into 2470 2 times, resulting in a remainder of 548.
The number 2 becomes the next digit in our result. 
Result so far: 29678.72736732
If we take 1922 away from 2470, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

After the division, we end up with 29678.72736732 and a remainder of 5.48e-07.
