We're dividing 43148717 by 86 
We want to figure out the number of times 43148717 can be divided by 86.

Going ahead to step 1:
4 divided by 86 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
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 / 86

On to step 2:
When dividing 43 by 86, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 86

On to step 3:
431 divided by 86 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 430 from 431 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 86

Advancing to step 4:
The number 86 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 14, we end up with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 86

Advancing to step 5:
When dividing 148 by 86, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 501.0
If we subtract 86 from 148, we get 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 86

Moving on to step 6:
86 can be fit into 627 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 5017.0
If we take 602 away from 627, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 86

Let's proceed to step 7:
86 can be fit into 251 2 times, resulting in a remainder of 79.
The next digit of our result is 2. 
Result so far: 50172.0
Subtract 172 from 251 to get 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 86

Moving on to step 8:
797 divided by 86 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 501729.0
Subtracting 774 from 797 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
If we divide 230 by 86, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 501729.2
The remainder is 58 after subtracting 172 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
580 divided by 86 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 501729.26
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 501729.267
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 501729.2674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
86 goes into 360 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 501729.26744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 501729.26744 with a balance of 1.6e-05.
