We look at the division of 12540137 by 897 
We want to figure out the number of times 12540137 can be divided 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
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 897

On to step 2:
The number 897 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 897

Step 3:
The number 897 fits into 125 0 times, leaving a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Bring next digit (4) of the dividend behind the 125 and repeat the process: 1254 / 897

Step 4:
When dividing 1254 by 897, we get 1 with a remainder of 357.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 897 away from 1254, we end up with 357.
Include the next digit (0) from the dividend after 357, then repeat: 3570 / 897

Moving on to step 5:
The number 897 fits into 3570 3 times, leaving a remainder of 879.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 879 after subtracting 2691 from 3570.
Include the next digit (1) from the dividend after 879, then repeat: 8791 / 897

Step 6:
The number 897 fits into 8791 9 times, leaving a remainder of 718.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 718 after subtracting 8073 from 8791.
Grab the next digit (3) from the dividend, add it to 718, then carry on: 7183 / 897

Advancing to step 7:
The number 897 fits into 7183 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1398.0
Subtract 7176 from 7183 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 897

Going ahead to step 8:
If we divide 77 by 897, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 13980.0
Subtracting 0 from 77 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
When dividing 770 by 897, we get 0 with a remainder of 770.
The next digit of our result is 0. 
Result so far: 13980.0
The remainder is 770 after subtracting 0 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 10:
897 can be fit into 7700 8 times, resulting in a remainder of 524.
Put 8 as the next digit of the answer. 
Result so far: 13980.08
The remainder is 524 after subtracting 7176 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 11:
If we divide 5240 by 897, we get 5 and a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 13980.085
Subtract 4485 from 5240 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Step 12:
The number 897 fits into 7550 8 times, leaving a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 13980.0858
Deduct 7176 from 7550 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 13:
3740 divided by 897 is 4 with a remainder of 152.
The next digit of our result is 4. 
Result so far: 13980.08584
If we subtract 3588 from 3740, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
The number 897 fits into 1520 1 times, leaving a remainder of 623.
Write down 1 as next digit of the result. 
Result so far: 13980.085841
If we subtract 897 from 1520, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 15:
897 can be fit into 6230 6 times, resulting in a remainder of 848.
Record the quotient 6 as the next digit in the result. 
Result so far: 13980.0858416
If we take 5382 away from 6230, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

On to step 16:
8480 divided by 897 is 9 with a remainder of 407.
The number 9 becomes the next digit in our result. 
Result so far: 13980.08584169
The remainder is 407 after subtracting 8073 from 8480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

The final outcome is 13980.08584169, with a leftover of 4.07e-07.
