We're dividing 43504567 by 806 
We want to figure out the number of times 43504567 can be divided by 806.

On to step 1:
The number 806 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 806

Let's proceed to step 2:
When dividing 43 by 806, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 806

Step 3:
If we divide 435 by 806, we get 0 and a remainder of 435.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 435 and we're left with 435.
Include the next digit (0) from the dividend after 435, then repeat: 4350 / 806

On to step 4:
When dividing 4350 by 806, we get 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4030 from 4350, we get 320.
Bring next digit (4) of the dividend behind the 320 and repeat the process: 3204 / 806

Let's proceed to step 5:
When dividing 3204 by 806, we get 3 with a remainder of 786.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2418 from 3204 and we're left with 786.
Append the next digit (5) from the dividend to 786 and continue with: 7865 / 806

Advancing to step 6:
If we divide 7865 by 806, we get 9 and a remainder of 611.
Use 9 as the next digit of our solution. 
Result so far: 539.0
Subtract 7254 from 7865 to get 611.
Bring next digit (6) of the dividend behind the 611 and repeat the process: 6116 / 806

Going ahead to step 7:
6116 divided by 806 is 7 with a remainder of 474.
Put 7 as the next digit of the answer. 
Result so far: 5397.0
Subtracting 5642 from 6116 leaves us with 474.
Fetch the next digit (7) from the dividend, attach it to 474 and continue: 4747 / 806

Going ahead to step 8:
The number 806 fits into 4747 5 times, leaving a remainder of 717.
Record the quotient 5 as the next digit in the result. 
Result so far: 53975.0
If we subtract 4030 from 4747, we get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Going ahead to step 9:
806 goes into 7170 8 times with a remainder of 722.
Put 8 as the next digit of the answer. 
Result so far: 53975.8
Subtracting 6448 from 7170 leaves us with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Going ahead to step 10:
If we divide 7220 by 806, we get 8 and a remainder of 772.
Put 8 as the next digit of the answer. 
Result so far: 53975.88
The remainder is 772 after subtracting 6448 from 7220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

After the division, we end up with 53975.88 and a remainder of 0.772.
