We're dividing 80011591 by 125 
We're looking to find how many times 125 goes into 80011591.

Let's proceed to step 1:
125 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 125

Let's proceed to step 2:
125 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 125

Advancing to step 3:
If we divide 800 by 125, we get 6 and a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 750 from 800 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 125

On to step 4:
If we divide 501 by 125, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 1 after subtracting 500 from 501.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 125

Step 5:
11 divided by 125 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 640.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 125

Step 6:
125 goes into 115 0 times with a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 6400.0
Subtracting 0 from 115 leaves us with 115.
Grab the next digit (9) from the dividend, add it to 115, then carry on: 1159 / 125

Let's proceed to step 7:
125 goes into 1159 9 times with a remainder of 34.
The next digit of our result is 9. 
Result so far: 64009.0
Subtract 1125 from 1159 to get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 125

On to step 8:
125 can be fit into 341 2 times, resulting in a remainder of 91.
The next digit of our result is 2. 
Result so far: 640092.0
Deduct 250 from 341 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
When dividing 910 by 125, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 640092.7
If we subtract 875 from 910, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
125 goes into 350 2 times with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 640092.72
If we subtract 250 from 350, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
If we divide 1000 by 125, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 640092.728
Subtracting 1000 from 1000 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 125, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 640092.728
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
0 divided by 125 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 640092.728
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 640092.728, with a leftover of 0.0.
