86434111 divided by 720 
We want to figure out the number of times 86434111 can be divided by 720.

Let's proceed to step 1:
If we divide 8 by 720, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 720

Step 2:
When dividing 86 by 720, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 720

Going ahead to step 3:
720 goes into 864 1 times with a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 720 from 864, we get 144.
Fetch the next digit (3) from the dividend, attach it to 144 and continue: 1443 / 720

Going ahead to step 4:
When dividing 1443 by 720, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1440 from 1443 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 720

Advancing to step 5:
34 divided by 720 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 720

Let's proceed to step 6:
The number 720 fits into 341 0 times, leaving a remainder of 341.
Record the quotient 0 as the next digit in the result. 
Result so far: 1200.0
The remainder is 341 after subtracting 0 from 341.
Take the next digit (1) from the dividend and append it to 341, then repeat: 3411 / 720

Step 7:
If we divide 3411 by 720, we get 4 and a remainder of 531.
Use 4 as the next digit of our solution. 
Result so far: 12004.0
Subtract 2880 from 3411 to get 531.
Append the next digit (1) from the dividend to 531 and continue with: 5311 / 720

On to step 8:
720 can be fit into 5311 7 times, resulting in a remainder of 271.
Write down 7 as next digit of the result. 
Result so far: 120047.0
If we subtract 5040 from 5311, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
720 goes into 2710 3 times with a remainder of 550.
The number 3 becomes the next digit in our result. 
Result so far: 120047.3
The remainder is 550 after subtracting 2160 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 10:
720 can be fit into 5500 7 times, resulting in a remainder of 460.
Use 7 as the next digit of our solution. 
Result so far: 120047.37
If we take 5040 away from 5500, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
720 can be fit into 4600 6 times, resulting in a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 120047.376
If we take 4320 away from 4600, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
720 goes into 2800 3 times with a remainder of 640.
Record the quotient 3 as the next digit in the result. 
Result so far: 120047.3763
Subtract 2160 from 2800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
6400 divided by 720 is 8 with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 120047.37638
Subtract 5760 from 6400 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
The number 720 fits into 6400 8 times, leaving a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 120047.376388
The remainder is 640 after subtracting 5760 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 120047.376388 with a remainder of 6.4e-05.
