We look at the division of 86496907 by 599 
We're looking to find how many times 599 goes into 86496907.

Advancing to step 1:
If we divide 8 by 599, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 599

Step 2:
When dividing 86 by 599, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 599

Let's proceed to step 3:
599 goes into 864 1 times with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 599 away from 864, we end up with 265.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 599

Advancing to step 4:
2659 divided by 599 is 4 with a remainder of 263.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2396 from 2659 leaves us with 263.
Fetch the next digit (6) from the dividend, attach it to 263 and continue: 2636 / 599

Moving on to step 5:
599 goes into 2636 4 times with a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
If we subtract 2396 from 2636, we get 240.
Include the next digit (9) from the dividend after 240, then repeat: 2409 / 599

Let's proceed to step 6:
If we divide 2409 by 599, we get 4 and a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 1444.0
The remainder is 13 after subtracting 2396 from 2409.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 599

Advancing to step 7:
599 can be fit into 130 0 times, resulting in a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 14440.0
Subtract 0 from 130 to get 130.
Include the next digit (7) from the dividend after 130, then repeat: 1307 / 599

Step 8:
The number 599 fits into 1307 2 times, leaving a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 144402.0
The remainder is 109 after subtracting 1198 from 1307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
599 can be fit into 1090 1 times, resulting in a remainder of 491.
Put 1 as the next digit of the answer. 
Result so far: 144402.1
If we take 599 away from 1090, we end up with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 10:
If we divide 4910 by 599, we get 8 and a remainder of 118.
The next digit of our result is 8. 
Result so far: 144402.18
Deduct 4792 from 4910 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 11:
If we divide 1180 by 599, we get 1 and a remainder of 581.
The next digit of our result is 1. 
Result so far: 144402.181
Deduct 599 from 1180 and we're left with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 12:
The number 599 fits into 5810 9 times, leaving a remainder of 419.
The number 9 becomes the next digit in our result. 
Result so far: 144402.1819
Deduct 5391 from 5810 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 13:
4190 divided by 599 is 6 with a remainder of 596.
The number 6 becomes the next digit in our result. 
Result so far: 144402.18196
If we subtract 3594 from 4190, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 14:
599 can be fit into 5960 9 times, resulting in a remainder of 569.
The next digit of our result is 9. 
Result so far: 144402.181969
If we take 5391 away from 5960, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 15:
If we divide 5690 by 599, we get 9 and a remainder of 299.
Write down 9 as next digit of the result. 
Result so far: 144402.1819699
Subtracting 5391 from 5690 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

In conclusion, the division gives 144402.1819699 with a balance of 2.99e-06.
