Let's divide 43572129 by 715
Let's see how many times 715 fits into 43572129.

Advancing to step 1:
715 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
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 / 715

Step 2:
715 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 715

Advancing to step 3:
The number 715 fits into 435 0 times, leaving a remainder of 435.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 435, we get 435.
Bring next digit (7) of the dividend behind the 435 and repeat the process: 4357 / 715

Step 4:
715 can be fit into 4357 6 times, resulting in a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 67 after subtracting 4290 from 4357.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 715

Going ahead to step 5:
When dividing 672 by 715, we get 0 with a remainder of 672.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtract 0 from 672 to get 672.
Fetch the next digit (1) from the dividend, attach it to 672 and continue: 6721 / 715

Advancing to step 6:
If we divide 6721 by 715, we get 9 and a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 609.0
If we take 6435 away from 6721, we end up with 286.
Bring next digit (2) of the dividend behind the 286 and repeat the process: 2862 / 715

Let's proceed to step 7:
If we divide 2862 by 715, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 6094.0
If we take 2860 away from 2862, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 715

On to step 8:
The number 715 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 60940.0
Deduct 0 from 29 and we're left 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.

On to step 9:
When dividing 290 by 715, we get 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 60940.0
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 10:
715 goes into 2900 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 60940.04
If we take 2860 away from 2900, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
715 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 60940.04
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 715, we get 5 and a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 60940.0405
Deduct 3575 from 4000 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 13:
715 can be fit into 4250 5 times, resulting in a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 60940.04055
Subtracting 3575 from 4250 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

The final outcome is 60940.04055, with a leftover of 0.000675.
