Let's divide 12965990 by 897
Our goal is to divide 12965990 by 897.

Step 1:
If we divide 1 by 897, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 897

Going ahead to step 2:
897 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 897

Advancing to step 3:
897 goes into 129 0 times with a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Append the next digit (6) from the dividend to 129 and continue with: 1296 / 897

Advancing to step 4:
The number 897 fits into 1296 1 times, leaving a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 897 from 1296, we get 399.
Fetch the next digit (5) from the dividend, attach it to 399 and continue: 3995 / 897

Advancing to step 5:
897 can be fit into 3995 4 times, resulting in a remainder of 407.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 3588 away from 3995, we end up with 407.
Bring next digit (9) of the dividend behind the 407 and repeat the process: 4079 / 897

Advancing to step 6:
When dividing 4079 by 897, we get 4 with a remainder of 491.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we subtract 3588 from 4079, we get 491.
Bring next digit (9) of the dividend behind the 491 and repeat the process: 4919 / 897

On to step 7:
When dividing 4919 by 897, we get 5 with a remainder of 434.
Write down 5 as next digit of the result. 
Result so far: 1445.0
Subtracting 4485 from 4919 leaves us with 434.
Include the next digit (0) from the dividend after 434, then repeat: 4340 / 897

On to step 8:
If we divide 4340 by 897, we get 4 and a remainder of 752.
Put 4 as the next digit of the answer. 
Result so far: 14454.0
Subtract 3588 from 4340 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 9:
If we divide 7520 by 897, we get 8 and a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 14454.8
Subtracting 7176 from 7520 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 10:
If we divide 3440 by 897, we get 3 and a remainder of 749.
Put 3 as the next digit of the answer. 
Result so far: 14454.83
If we take 2691 away from 3440, we end up with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Step 11:
If we divide 7490 by 897, we get 8 and a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 14454.838
If we subtract 7176 from 7490, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 12:
The number 897 fits into 3140 3 times, leaving a remainder of 449.
Write down 3 as next digit of the result. 
Result so far: 14454.8383
Subtracting 2691 from 3140 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 13:
4490 divided by 897 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 14454.83835
Subtracting 4485 from 4490 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
If we divide 50 by 897, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 14454.83835
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
897 goes into 500 0 times with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 14454.83835
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 14454.83835, and the remainder is 5e-06.
