19505509 ÷ 125 
Let's see how many times 125 fits into 19505509.

Moving on to step 1:
125 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 125

Moving on to step 2:
When dividing 19 by 125, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 125

Advancing to step 3:
195 divided by 125 is 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 1.0
If we take 125 away from 195, we end up with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 125

Advancing to step 4:
When dividing 700 by 125, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 625 from 700 to get 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 125

Moving on to step 5:
755 divided by 125 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 156.0
If we take 750 away from 755, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 125

On to step 6:
When dividing 55 by 125, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 1560.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 125

On to step 7:
The number 125 fits into 550 4 times, leaving a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 15604.0
If we subtract 500 from 550, we get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 125

Advancing to step 8:
509 divided by 125 is 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 156044.0
The remainder is 9 after subtracting 500 from 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
If we divide 90 by 125, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 156044.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
125 can be fit into 900 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 156044.07
The remainder is 25 after subtracting 875 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
When dividing 250 by 125, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 156044.072
The remainder is 0 after subtracting 250 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 125 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 156044.072
If we take 0 away from 0, we end up 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.

Advancing to step 13:
125 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 156044.072
The remainder is 0 after subtracting 0 from 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 result is 156044.072 with a remainder of 0.0.
