80891838 ÷ 518 
Let's see how many times 518 fits into 80891838.

On to step 1:
518 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 518

On to step 2:
The number 518 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 518

Moving on to step 3:
When dividing 808 by 518, we get 1 with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 518 from 808, we get 290.
Include the next digit (9) from the dividend after 290, then repeat: 2909 / 518

On to step 4:
518 can be fit into 2909 5 times, resulting in a remainder of 319.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2590 away from 2909, we end up with 319.
Grab the next digit (1) from the dividend, add it to 319, then carry on: 3191 / 518

On to step 5:
3191 divided by 518 is 6 with a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we take 3108 away from 3191, we end up with 83.
Fetch the next digit (8) from the dividend, attach it to 83 and continue: 838 / 518

Moving on to step 6:
If we divide 838 by 518, we get 1 and a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 1561.0
The remainder is 320 after subtracting 518 from 838.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 518

On to step 7:
When dividing 3203 by 518, we get 6 with a remainder of 95.
Record the quotient 6 as the next digit in the result. 
Result so far: 15616.0
Subtracting 3108 from 3203 leaves us with 95.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 518

Moving on to step 8:
958 divided by 518 is 1 with a remainder of 440.
The next digit of our result is 1. 
Result so far: 156161.0
If we subtract 518 from 958, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 9:
4400 divided by 518 is 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 156161.8
If we subtract 4144 from 4400, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 10:
518 goes into 2560 4 times with a remainder of 488.
Record the quotient 4 as the next digit in the result. 
Result so far: 156161.84
If we subtract 2072 from 2560, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
4880 divided by 518 is 9 with a remainder of 218.
The next digit of our result is 9. 
Result so far: 156161.849
Subtract 4662 from 4880 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
2180 divided by 518 is 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 156161.8494
The remainder is 108 after subtracting 2072 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
1080 divided by 518 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 156161.84942
Subtracting 1036 from 1080 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
When dividing 440 by 518, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 156161.84942
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 15:
518 goes into 4400 8 times with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 156161.8494208
If we subtract 4144 from 4400, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
When dividing 2560 by 518, we get 4 with a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 156161.84942084
If we take 2072 away from 2560, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 156161.84942084 with a remainder of 4.88e-07.
