16723345 ÷ 43 
We want to figure out the number of times 16723345 can be divided by 43.

Advancing to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 43

Let's proceed to step 2:
The number 43 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 43

Advancing to step 3:
The number 43 fits into 167 3 times, leaving a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 129 from 167 to get 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 43

Let's proceed to step 4:
382 divided by 43 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 344 from 382 leaves us with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 43

Going ahead to step 5:
43 can be fit into 383 8 times, resulting in a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
Deduct 344 from 383 and we're left with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 43

Advancing to step 6:
43 can be fit into 393 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3889.0
Subtract 387 from 393 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 43

Advancing to step 7:
When dividing 64 by 43, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 38891.0
Subtract 43 from 64 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 43

Going ahead to step 8:
215 divided by 43 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 388915.0
The remainder is 0 after subtracting 215 from 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 43 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 388915.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 43, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 388915.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 388915.0, with a leftover of 0.0.
