We look at the division of 25559690 by 670 
Let's see how many times 670 fits into 25559690.

Let's proceed to step 1:
The number 670 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 670

On to step 2:
670 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 670

Step 3:
255 divided by 670 is 0 with a remainder of 255.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Bring next digit (5) of the dividend behind the 255 and repeat the process: 2555 / 670

On to step 4:
If we divide 2555 by 670, we get 3 and a remainder of 545.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2010 from 2555 leaves us with 545.
Bring next digit (9) of the dividend behind the 545 and repeat the process: 5459 / 670

Let's proceed to step 5:
5459 divided by 670 is 8 with a remainder of 99.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 5360 from 5459 leaves us with 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 670

Advancing to step 6:
670 goes into 996 1 times with a remainder of 326.
The number 1 becomes the next digit in our result. 
Result so far: 381.0
Deduct 670 from 996 and we're left with 326.
Include the next digit (9) from the dividend after 326, then repeat: 3269 / 670

Advancing to step 7:
670 goes into 3269 4 times with a remainder of 589.
The number 4 becomes the next digit in our result. 
Result so far: 3814.0
Subtract 2680 from 3269 to get 589.
Fetch the next digit (0) from the dividend, attach it to 589 and continue: 5890 / 670

Moving on to step 8:
When dividing 5890 by 670, we get 8 with a remainder of 530.
Record the quotient 8 as the next digit in the result. 
Result so far: 38148.0
Deduct 5360 from 5890 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 9:
If we divide 5300 by 670, we get 7 and a remainder of 610.
Write down 7 as next digit of the result. 
Result so far: 38148.7
Subtracting 4690 from 5300 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 10:
670 can be fit into 6100 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 38148.79
The remainder is 70 after subtracting 6030 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
670 goes into 700 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 38148.791
Subtracting 670 from 700 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 670, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 38148.791
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
670 goes into 3000 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 38148.79104
Subtract 2680 from 3000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
If we divide 3200 by 670, we get 4 and a remainder of 520.
The next digit of our result is 4. 
Result so far: 38148.791044
The remainder is 520 after subtracting 2680 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

After the division, we end up with 38148.791044 and a remainder of 5.2e-05.
