We divide 12830409 by 426
We want to figure out the number of times 12830409 can be divided by 426.

Going ahead to step 1:
1 divided by 426 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
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 / 426

Let's proceed to step 2:
426 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 426

Step 3:
426 goes into 128 0 times with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 426

Advancing to step 4:
When dividing 1283 by 426, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1278 from 1283 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 426

Going ahead to step 5:
50 divided by 426 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 426

Moving on to step 6:
When dividing 504 by 426, we get 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 301.0
Deduct 426 from 504 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 426

On to step 7:
426 goes into 780 1 times with a remainder of 354.
The number 1 becomes the next digit in our result. 
Result so far: 3011.0
Deduct 426 from 780 and we're left with 354.
Bring next digit (9) of the dividend behind the 354 and repeat the process: 3549 / 426

Going ahead to step 8:
If we divide 3549 by 426, we get 8 and a remainder of 141.
Use 8 as the next digit of our solution. 
Result so far: 30118.0
If we subtract 3408 from 3549, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
426 goes into 1410 3 times with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 30118.3
Deduct 1278 from 1410 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
The number 426 fits into 1320 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 30118.33
The remainder is 42 after subtracting 1278 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 30118.33 and a remainder of 0.042.
