We're dividing 19938578 by 254 
We want to divide 19938578 by 254.

Advancing to step 1:
1 divided by 254 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 254

On to step 2:
254 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 254

Step 3:
If we divide 199 by 254, we get 0 and a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Bring next digit (3) of the dividend behind the 199 and repeat the process: 1993 / 254

Going ahead to step 4:
The number 254 fits into 1993 7 times, leaving a remainder of 215.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 1778 from 1993 leaves us with 215.
Include the next digit (8) from the dividend after 215, then repeat: 2158 / 254

Step 5:
When dividing 2158 by 254, we get 8 with a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 2032 from 2158 leaves us with 126.
Take the next digit (5) from the dividend and append it to 126, then repeat: 1265 / 254

On to step 6:
1265 divided by 254 is 4 with a remainder of 249.
Use 4 as the next digit of our solution. 
Result so far: 784.0
If we take 1016 away from 1265, we end up with 249.
Append the next digit (7) from the dividend to 249 and continue with: 2497 / 254

Advancing to step 7:
254 can be fit into 2497 9 times, resulting in a remainder of 211.
The next digit of our result is 9. 
Result so far: 7849.0
Subtracting 2286 from 2497 leaves us with 211.
Fetch the next digit (8) from the dividend, attach it to 211 and continue: 2118 / 254

Let's proceed to step 8:
254 goes into 2118 8 times with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 78498.0
Deduct 2032 from 2118 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
When dividing 860 by 254, we get 3 with a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 78498.3
If we take 762 away from 860, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
980 divided by 254 is 3 with a remainder of 218.
Record the quotient 3 as the next digit in the result. 
Result so far: 78498.33
Deduct 762 from 980 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 78498.33, with a leftover of 0.218.
