We look at the division of 4571646 by 805 
We want to figure out the number of times 4571646 can be divided by 805.

Moving on to step 1:
805 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 805

Step 2:
The number 805 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 805

Let's proceed to step 3:
457 divided by 805 is 0 with a remainder of 457.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 457 and we're left with 457.
Include the next digit (1) from the dividend after 457, then repeat: 4571 / 805

Advancing to step 4:
The number 805 fits into 4571 5 times, leaving a remainder of 546.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4025 from 4571 leaves us with 546.
Fetch the next digit (6) from the dividend, attach it to 546 and continue: 5466 / 805

Let's proceed to step 5:
When dividing 5466 by 805, we get 6 with a remainder of 636.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 636 after subtracting 4830 from 5466.
Take the next digit (4) from the dividend and append it to 636, then repeat: 6364 / 805

Going ahead to step 6:
If we divide 6364 by 805, we get 7 and a remainder of 729.
Write down 7 as next digit of the result. 
Result so far: 567.0
Subtract 5635 from 6364 to get 729.
Grab the next digit (6) from the dividend, add it to 729, then carry on: 7296 / 805

Moving on to step 7:
When dividing 7296 by 805, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 5679.0
If we subtract 7245 from 7296, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
If we divide 510 by 805, we get 0 and a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 5679.0
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 9:
The number 805 fits into 5100 6 times, leaving a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 5679.06
Deduct 4830 from 5100 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
When dividing 2700 by 805, we get 3 with a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 5679.063
Deduct 2415 from 2700 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 11:
805 can be fit into 2850 3 times, resulting in a remainder of 435.
The next digit of our result is 3. 
Result so far: 5679.0633
Deduct 2415 from 2850 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

After the division, we end up with 5679.0633 and a remainder of 0.00435.
