We're dividing 12881365 by 606 
Our goal is to divide 12881365 by 606.

Let's proceed to step 1:
The number 606 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 606

Going ahead to step 2:
The number 606 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 606

Let's proceed to step 3:
If we divide 128 by 606, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Take the next digit (8) from the dividend and append it to 128, then repeat: 1288 / 606

Step 4:
The number 606 fits into 1288 2 times, leaving a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1212 from 1288 leaves us with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 606

Advancing to step 5:
The number 606 fits into 761 1 times, leaving a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 606 from 761, we get 155.
Bring next digit (3) of the dividend behind the 155 and repeat the process: 1553 / 606

Moving on to step 6:
606 goes into 1553 2 times with a remainder of 341.
Write down 2 as next digit of the result. 
Result so far: 212.0
Subtracting 1212 from 1553 leaves us with 341.
Include the next digit (6) from the dividend after 341, then repeat: 3416 / 606

Step 7:
606 goes into 3416 5 times with a remainder of 386.
The next digit of our result is 5. 
Result so far: 2125.0
Deduct 3030 from 3416 and we're left with 386.
Take the next digit (5) from the dividend and append it to 386, then repeat: 3865 / 606

Advancing to step 8:
The number 606 fits into 3865 6 times, leaving a remainder of 229.
Write down 6 as next digit of the result. 
Result so far: 21256.0
Subtracting 3636 from 3865 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 9:
The number 606 fits into 2290 3 times, leaving a remainder of 472.
Record the quotient 3 as the next digit in the result. 
Result so far: 21256.3
Subtract 1818 from 2290 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 10:
If we divide 4720 by 606, we get 7 and a remainder of 478.
Put 7 as the next digit of the answer. 
Result so far: 21256.37
Subtracting 4242 from 4720 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 11:
The number 606 fits into 4780 7 times, leaving a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 21256.377
If we subtract 4242 from 4780, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final outcome is 21256.377, with a leftover of 0.0538.
