Let's divide 42888665 by 39
We want to figure out the number of times 42888665 can be divided by 39.

Step 1:
39 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 39

On to step 2:
If we divide 42 by 39, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 39 from 42, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 39

Moving on to step 3:
39 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 38, we end up with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 39

On to step 4:
39 can be fit into 388 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
If we take 351 away from 388, we end up with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 39

Advancing to step 5:
378 divided by 39 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 1099.0
Deduct 351 from 378 and we're left with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 39

Going ahead to step 6:
The number 39 fits into 276 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 10997.0
If we take 273 away from 276, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 39

Advancing to step 7:
39 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 109970.0
Deduct 0 from 36 and we're left with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 39

Step 8:
39 can be fit into 365 9 times, resulting in a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 1099709.0
If we subtract 351 from 365, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1099709.3
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
The number 39 fits into 230 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 1099709.35
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 39 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 1099709.358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
39 goes into 380 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 1099709.3589
Deduct 351 from 380 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1099709.35897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1099709.358974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
If we divide 140 by 39, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1099709.3589743
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 16:
39 goes into 230 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1099709.35897435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 1099709.35897435 with a balance of 3.5e-08.
