Let's divide 12900266 by 425
We want to divide 12900266 by 425.

Advancing to step 1:
The number 425 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 425

On to step 2:
The number 425 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 425

On to step 3:
425 goes into 129 0 times with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 129 leaves us with 129.
Fetch the next digit (0) from the dividend, attach it to 129 and continue: 1290 / 425

Step 4:
425 can be fit into 1290 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1275 away from 1290, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 425

On to step 5:
When dividing 150 by 425, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 150 to get 150.
Bring next digit (2) of the dividend behind the 150 and repeat the process: 1502 / 425

On to step 6:
If we divide 1502 by 425, we get 3 and a remainder of 227.
The next digit of our result is 3. 
Result so far: 303.0
Deduct 1275 from 1502 and we're left with 227.
Take the next digit (6) from the dividend and append it to 227, then repeat: 2276 / 425

Step 7:
If we divide 2276 by 425, we get 5 and a remainder of 151.
The number 5 becomes the next digit in our result. 
Result so far: 3035.0
Deduct 2125 from 2276 and we're left with 151.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 425

Moving on to step 8:
425 goes into 1516 3 times with a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 30353.0
If we subtract 1275 from 1516, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 9:
When dividing 2410 by 425, we get 5 with a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 30353.5
If we subtract 2125 from 2410, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 425 fits into 2850 6 times, leaving a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 30353.56
The remainder is 300 after subtracting 2550 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
425 goes into 3000 7 times with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 30353.567
If we take 2975 away from 3000, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
425 can be fit into 250 0 times, resulting in a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 30353.567
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
425 goes into 2500 5 times with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 30353.56705
If we subtract 2125 from 2500, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 14:
3750 divided by 425 is 8 with a remainder of 350.
Write down 8 as next digit of the result. 
Result so far: 30353.567058
Deduct 3400 from 3750 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 15:
When dividing 3500 by 425, we get 8 with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 30353.5670588
Deduct 3400 from 3500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 30353.5670588 with a remainder of 1e-06.
