43563945 ÷ 628 
Let's see how many times 628 fits into 43563945.

Advancing to step 1:
628 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 628

On to step 2:
When dividing 43 by 628, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 628

Going ahead to step 3:
628 goes into 435 0 times with a remainder of 435.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 435, we end up with 435.
Take the next digit (6) from the dividend and append it to 435, then repeat: 4356 / 628

Let's proceed to step 4:
If we divide 4356 by 628, we get 6 and a remainder of 588.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3768 from 4356, we get 588.
Include the next digit (3) from the dividend after 588, then repeat: 5883 / 628

Advancing to step 5:
628 goes into 5883 9 times with a remainder of 231.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 5652 from 5883 leaves us with 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 628

Going ahead to step 6:
628 can be fit into 2319 3 times, resulting in a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 693.0
If we subtract 1884 from 2319, we get 435.
Bring next digit (4) of the dividend behind the 435 and repeat the process: 4354 / 628

On to step 7:
The number 628 fits into 4354 6 times, leaving a remainder of 586.
Use 6 as the next digit of our solution. 
Result so far: 6936.0
Deduct 3768 from 4354 and we're left with 586.
Append the next digit (5) from the dividend to 586 and continue with: 5865 / 628

On to step 8:
628 goes into 5865 9 times with a remainder of 213.
The next digit of our result is 9. 
Result so far: 69369.0
If we subtract 5652 from 5865, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 9:
628 can be fit into 2130 3 times, resulting in a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 69369.3
Deduct 1884 from 2130 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 10:
628 can be fit into 2460 3 times, resulting in a remainder of 576.
Use 3 as the next digit of our solution. 
Result so far: 69369.33
Deduct 1884 from 2460 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final outcome is 69369.33, with a leftover of 0.576.
