We look at the division of 17088910 by 407 
We're looking to find how many times 407 goes into 17088910.

Going ahead to step 1:
When dividing 1 by 407, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 407

Moving on to step 2:
When dividing 17 by 407, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 407

Going ahead to step 3:
407 goes into 170 0 times with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 170, we end up with 170.
Grab the next digit (8) from the dividend, add it to 170, then carry on: 1708 / 407

Advancing to step 4:
407 can be fit into 1708 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 80 after subtracting 1628 from 1708.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 407

Let's proceed to step 5:
The number 407 fits into 808 1 times, leaving a remainder of 401.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 407 from 808 leaves us with 401.
Fetch the next digit (9) from the dividend, attach it to 401 and continue: 4019 / 407

Step 6:
407 can be fit into 4019 9 times, resulting in a remainder of 356.
The next digit of our result is 9. 
Result so far: 419.0
If we subtract 3663 from 4019, we get 356.
Bring next digit (1) of the dividend behind the 356 and repeat the process: 3561 / 407

Going ahead to step 7:
If we divide 3561 by 407, we get 8 and a remainder of 305.
Use 8 as the next digit of our solution. 
Result so far: 4198.0
If we take 3256 away from 3561, we end up with 305.
Append the next digit (0) from the dividend to 305 and continue with: 3050 / 407

Going ahead to step 8:
When dividing 3050 by 407, we get 7 with a remainder of 201.
The next digit of our result is 7. 
Result so far: 41987.0
Subtracting 2849 from 3050 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 9:
When dividing 2010 by 407, we get 4 with a remainder of 382.
Write down 4 as next digit of the result. 
Result so far: 41987.4
The remainder is 382 after subtracting 1628 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
407 can be fit into 3820 9 times, resulting in a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 41987.49
Deduct 3663 from 3820 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 11:
If we divide 1570 by 407, we get 3 and a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 41987.493
If we subtract 1221 from 1570, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 12:
3490 divided by 407 is 8 with a remainder of 234.
Use 8 as the next digit of our solution. 
Result so far: 41987.4938
Subtract 3256 from 3490 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 13:
When dividing 2340 by 407, we get 5 with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 41987.49385
Deduct 2035 from 2340 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 14:
3050 divided by 407 is 7 with a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 41987.493857
Deduct 2849 from 3050 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 15:
2010 divided by 407 is 4 with a remainder of 382.
The number 4 becomes the next digit in our result. 
Result so far: 41987.4938574
Subtract 1628 from 2010 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 16:
When dividing 3820 by 407, we get 9 with a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 41987.49385749
The remainder is 157 after subtracting 3663 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

After the division, we end up with 41987.49385749 and a remainder of 1.57e-07.
