When dividing 4 by 905, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 905

Moving on to step 2:
When dividing 45 by 905, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 905

Let's proceed to step 3:
905 goes into 453 0 times with a remainder of 453.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 453 leaves us with 453.
Bring next digit (3) of the dividend behind the 453 and repeat the process: 4533 / 905

Going ahead to step 4:
4533 divided by 905 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4525 from 4533 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 905

Advancing to step 5:
If we divide 89 by 905, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 89 to get 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 905

Step 6:
905 goes into 898 0 times with a remainder of 898.
Write down 0 as next digit of the result. 
Result so far: 500.0
Subtracting 0 from 898 leaves us with 898.
Grab the next digit (5) from the dividend, add it to 898, then carry on: 8985 / 905

Moving on to step 7:
When dividing 8985 by 905, we get 9 with a remainder of 840.
The next digit of our result is 9. 
Result so far: 5009.0
Subtracting 8145 from 8985 leaves us with 840.
Fetch the next digit (0) from the dividend, attach it to 840 and continue: 8400 / 905

Let's proceed to step 8:
8400 divided by 905 is 9 with a remainder of 255.
Record the quotient 9 as the next digit in the result. 
Result so far: 50099.0
Subtracting 8145 from 8400 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 9:
2550 divided by 905 is 2 with a remainder of 740.
Put 2 as the next digit of the answer. 
Result so far: 50099.2
Deduct 1810 from 2550 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 10:
905 can be fit into 7400 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 50099.28
Deduct 7240 from 7400 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 11:
If we divide 1600 by 905, we get 1 and a remainder of 695.
Use 1 as the next digit of our solution. 
Result so far: 50099.281
Deduct 905 from 1600 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 12:
905 can be fit into 6950 7 times, resulting in a remainder of 615.
Use 7 as the next digit of our solution. 
Result so far: 50099.2817
Subtracting 6335 from 6950 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 13:
905 goes into 6150 6 times with a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 50099.28176
The remainder is 720 after subtracting 5430 from 6150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 14:
The number 905 fits into 7200 7 times, leaving a remainder of 865.
Write down 7 as next digit of the result. 
Result so far: 50099.281767
Subtracting 6335 from 7200 leaves us with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Advancing to step 15:
The number 905 fits into 8650 9 times, leaving a remainder of 505.
Record the quotient 9 as the next digit in the result. 
Result so far: 50099.2817679
Subtracting 8145 from 8650 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 16:
905 goes into 5050 5 times with a remainder of 525.
The next digit of our result is 5. 
Result so far: 50099.28176795
The remainder is 525 after subtracting 4525 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The final result is 50099.28176795 with a remainder of 5.25e-07.
