We look at the division of 42488511 by 39 
Our goal is to divide 42488511 by 39.

Let's proceed to step 1:
39 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 39

Advancing to step 2:
39 can be fit into 42 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 39 from 42 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 39

Advancing to step 3:
39 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 34, we get 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 39

Advancing to step 4:
When dividing 348 by 39, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 108.0
If we subtract 312 from 348, we get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 39

Let's proceed to step 5:
If we divide 368 by 39, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 1089.0
Subtract 351 from 368 to get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 39

Going ahead to step 6:
39 can be fit into 175 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 10894.0
Subtract 156 from 175 to get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 39

Step 7:
39 can be fit into 191 4 times, resulting in a remainder of 35.
The next digit of our result is 4. 
Result so far: 108944.0
If we take 156 away from 191, we end up with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 39

Step 8:
If we divide 351 by 39, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1089449.0
Subtracting 351 from 351 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.

Moving on to step 9:
The number 39 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1089449.0
If we subtract 0 from 0, we 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.

Moving on to step 10:
39 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1089449.0
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 quotient of the division is 1089449.0, and the remainder is 0.0.
