43678405 divided by 623 
We want to figure out the number of times 43678405 can be divided by 623.

Let's proceed to step 1:
When dividing 4 by 623, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 623

Let's proceed to step 2:
When dividing 43 by 623, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 623

Moving on to step 3:
If we divide 436 by 623, we get 0 and a remainder of 436.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Grab the next digit (7) from the dividend, add it to 436, then carry on: 4367 / 623

Moving on to step 4:
The number 623 fits into 4367 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4361 from 4367 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 623

Step 5:
623 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 623

Advancing to step 6:
684 divided by 623 is 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
If we take 623 away from 684, we end up with 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 623

Advancing to step 7:
623 goes into 610 0 times with a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 7010.0
Subtract 0 from 610 to get 610.
Take the next digit (5) from the dividend and append it to 610, then repeat: 6105 / 623

On to step 8:
623 goes into 6105 9 times with a remainder of 498.
Record the quotient 9 as the next digit in the result. 
Result so far: 70109.0
Subtract 5607 from 6105 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 9:
The number 623 fits into 4980 7 times, leaving a remainder of 619.
Record the quotient 7 as the next digit in the result. 
Result so far: 70109.7
If we subtract 4361 from 4980, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Step 10:
When dividing 6190 by 623, we get 9 with a remainder of 583.
Write down 9 as next digit of the result. 
Result so far: 70109.79
If we take 5607 away from 6190, we end up with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 11:
If we divide 5830 by 623, we get 9 and a remainder of 223.
The number 9 becomes the next digit in our result. 
Result so far: 70109.799
Subtract 5607 from 5830 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

In conclusion, the division gives 70109.799 with a balance of 0.0223.
