We're dividing 19759421 by 125 
We want to divide 19759421 by 125.

Advancing to step 1:
125 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 125

Step 2:
125 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 125

On to step 3:
If we divide 197 by 125, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 125 from 197 leaves us with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 125

Let's proceed to step 4:
When dividing 725 by 125, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 100 after subtracting 625 from 725.
Include the next digit (9) from the dividend after 100, then repeat: 1009 / 125

Step 5:
The number 125 fits into 1009 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtracting 1000 from 1009 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 125

Going ahead to step 6:
125 can be fit into 94 0 times, resulting in a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 1580.0
Deduct 0 from 94 and we're left with 94.
Fetch the next digit (2) from the dividend, attach it to 94 and continue: 942 / 125

Going ahead to step 7:
125 can be fit into 942 7 times, resulting in a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 15807.0
If we subtract 875 from 942, we get 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 125

Going ahead to step 8:
125 goes into 671 5 times with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 158075.0
The remainder is 46 after subtracting 625 from 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
125 can be fit into 460 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 158075.3
The remainder is 85 after subtracting 375 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
125 can be fit into 850 6 times, resulting in a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 158075.36
If we take 750 away from 850, we end up with 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:
The number 125 fits into 1000 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 158075.368
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.

Let's proceed to step 12:
125 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 158075.368
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.

Step 13:
125 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 158075.368
Subtract 0 from 0 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.

After the division, we end up with 158075.368 and a remainder of 0.0.
