721612 divided by 43 
We want to figure out the number of times 721612 can be divided by 43.

Let's proceed to step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 43

Going ahead to step 2:
43 goes into 72 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 43 away from 72, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 43

Going ahead to step 3:
The number 43 fits into 291 6 times, leaving a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 258 away from 291, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 43

Moving on to step 4:
43 can be fit into 336 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
If we subtract 301 from 336, we get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 43

Moving on to step 5:
When dividing 351 by 43, we get 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 1678.0
Subtract 344 from 351 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 43

Going ahead to step 6:
The number 43 fits into 72 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 16781.0
Subtracting 43 from 72 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 16781.6
The remainder is 32 after subtracting 258 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
If we divide 320 by 43, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 16781.67
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
190 divided by 43 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 16781.674
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
When dividing 180 by 43, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 16781.6744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 16781.6744, with a leftover of 8e-05.
