64184993 ÷ 905 
Let's see how many times 905 fits into 64184993.

On to step 1:
905 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 905

Moving on to step 2:
The number 905 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 905

Step 3:
When dividing 641 by 905, we get 0 with a remainder of 641.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 641, we end up with 641.
Fetch the next digit (8) from the dividend, attach it to 641 and continue: 6418 / 905

Step 4:
905 goes into 6418 7 times with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6335 from 6418 leaves us with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 905

Let's proceed to step 5:
The number 905 fits into 834 0 times, leaving a remainder of 834.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 834 and we're left with 834.
Include the next digit (9) from the dividend after 834, then repeat: 8349 / 905

Moving on to step 6:
The number 905 fits into 8349 9 times, leaving a remainder of 204.
Write down 9 as next digit of the result. 
Result so far: 709.0
Subtracting 8145 from 8349 leaves us with 204.
Include the next digit (9) from the dividend after 204, then repeat: 2049 / 905

Let's proceed to step 7:
905 can be fit into 2049 2 times, resulting in a remainder of 239.
Put 2 as the next digit of the answer. 
Result so far: 7092.0
Subtract 1810 from 2049 to get 239.
Take the next digit (3) from the dividend and append it to 239, then repeat: 2393 / 905

Going ahead to step 8:
The number 905 fits into 2393 2 times, leaving a remainder of 583.
Put 2 as the next digit of the answer. 
Result so far: 70922.0
The remainder is 583 after subtracting 1810 from 2393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 9:
If we divide 5830 by 905, we get 6 and a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 70922.6
Subtract 5430 from 5830 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
905 can be fit into 4000 4 times, resulting in a remainder of 380.
The next digit of our result is 4. 
Result so far: 70922.64
If we take 3620 away from 4000, we end up 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.

Step 11:
When dividing 3800 by 905, we get 4 with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 70922.644
Deduct 3620 from 3800 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 70922.644 with a remainder of 0.018.
