We're dividing 17487850 by 455 
We're looking to find how many times 455 goes into 17487850.

Going ahead to step 1:
455 goes into 1 0 times with 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.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 455

On to step 2:
When dividing 17 by 455, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 455

Advancing to step 3:
174 divided by 455 is 0 with a remainder of 174.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 174, we end up with 174.
Fetch the next digit (8) from the dividend, attach it to 174 and continue: 1748 / 455

Advancing to step 4:
The number 455 fits into 1748 3 times, leaving a remainder of 383.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1365 from 1748 leaves us with 383.
Include the next digit (7) from the dividend after 383, then repeat: 3837 / 455

Let's proceed to step 5:
3837 divided by 455 is 8 with a remainder of 197.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 3640 from 3837, we get 197.
Append the next digit (8) from the dividend to 197 and continue with: 1978 / 455

Let's proceed to step 6:
When dividing 1978 by 455, we get 4 with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 384.0
Subtract 1820 from 1978 to get 158.
Include the next digit (5) from the dividend after 158, then repeat: 1585 / 455

Let's proceed to step 7:
If we divide 1585 by 455, we get 3 and a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 3843.0
Subtract 1365 from 1585 to get 220.
Include the next digit (0) from the dividend after 220, then repeat: 2200 / 455

Going ahead to step 8:
455 goes into 2200 4 times with a remainder of 380.
Use 4 as the next digit of our solution. 
Result so far: 38434.0
Deduct 1820 from 2200 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
The number 455 fits into 3800 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 38434.8
Deduct 3640 from 3800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
When dividing 1600 by 455, we get 3 with a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 38434.83
If we take 1365 away from 1600, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 11:
If we divide 2350 by 455, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 38434.835
If we take 2275 away from 2350, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
455 can be fit into 750 1 times, resulting in a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 38434.8351
The remainder is 295 after subtracting 455 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 13:
When dividing 2950 by 455, we get 6 with a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 38434.83516
Deduct 2730 from 2950 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
455 can be fit into 2200 4 times, resulting in a remainder of 380.
The number 4 becomes the next digit in our result. 
Result so far: 38434.835164
Deduct 1820 from 2200 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
The number 455 fits into 3800 8 times, leaving a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 38434.8351648
If we take 3640 away from 3800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
455 can be fit into 1600 3 times, resulting in a remainder of 235.
Use 3 as the next digit of our solution. 
Result so far: 38434.83516483
Subtract 1365 from 1600 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 38434.83516483 with a remainder of 2.35e-07.
