We look at the division of 80137793 by 125 
We want to figure out the number of times 80137793 can be divided by 125.

On to step 1:
If we divide 8 by 125, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 125

Moving on to step 2:
125 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 125

Step 3:
When dividing 801 by 125, we get 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 750 away from 801, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 125

Advancing to step 4:
125 goes into 513 4 times with a remainder of 13.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 500 from 513 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 125

Going ahead to step 5:
125 goes into 137 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Subtracting 125 from 137 leaves us with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 125

Going ahead to step 6:
127 divided by 125 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 6411.0
Deduct 125 from 127 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 125

On to step 7:
When dividing 29 by 125, we get 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 64110.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 125

Advancing to step 8:
When dividing 293 by 125, we get 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 641102.0
Subtract 250 from 293 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
125 can be fit into 430 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 641102.3
Subtracting 375 from 430 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
125 can be fit into 550 4 times, resulting in a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 641102.34
Subtract 500 from 550 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 125, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 641102.344
Subtract 500 from 500 to get 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 quotient of the division is 641102.344, and the remainder is 0.0.
