We divide 12470560 by 407
We want to divide 12470560 by 407.

Step 1:
407 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 407

Let's proceed to step 2:
The number 407 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 407

Going ahead to step 3:
If we divide 124 by 407, we get 0 and a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Include the next digit (7) from the dividend after 124, then repeat: 1247 / 407

Moving on to step 4:
The number 407 fits into 1247 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1221 from 1247, we get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 407

Moving on to step 5:
407 can be fit into 260 0 times, resulting in a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 260 leaves us with 260.
Include the next digit (5) from the dividend after 260, then repeat: 2605 / 407

Moving on to step 6:
When dividing 2605 by 407, we get 6 with a remainder of 163.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
Subtracting 2442 from 2605 leaves us with 163.
Fetch the next digit (6) from the dividend, attach it to 163 and continue: 1636 / 407

On to step 7:
407 can be fit into 1636 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3064.0
Deduct 1628 from 1636 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 407

Step 8:
407 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 30640.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
407 can be fit into 800 1 times, resulting in a remainder of 393.
Use 1 as the next digit of our solution. 
Result so far: 30640.1
If we take 407 away from 800, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 10:
The number 407 fits into 3930 9 times, leaving a remainder of 267.
Put 9 as the next digit of the answer. 
Result so far: 30640.19
The remainder is 267 after subtracting 3663 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 11:
When dividing 2670 by 407, we get 6 with a remainder of 228.
Use 6 as the next digit of our solution. 
Result so far: 30640.196
Subtract 2442 from 2670 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
If we divide 2280 by 407, we get 5 and a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 30640.1965
Subtract 2035 from 2280 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 13:
407 goes into 2450 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 30640.19656
If we subtract 2442 from 2450, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 407 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 30640.19656
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
When dividing 800 by 407, we get 1 with a remainder of 393.
The number 1 becomes the next digit in our result. 
Result so far: 30640.1965601
Subtracting 407 from 800 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 16:
407 goes into 3930 9 times with a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 30640.19656019
If we subtract 3663 from 3930, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

The final result is 30640.19656019 with a remainder of 2.67e-07.
