We divide 287128 by 39
We want to figure out the number of times 287128 can be divided by 39.

Step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 39

Moving on to step 2:
39 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 39

Step 3:
If we divide 287 by 39, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 273 from 287 to get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 39

Advancing to step 4:
The number 39 fits into 141 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 117 away from 141, we end up with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 39

Advancing to step 5:
39 can be fit into 242 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 736.0
Deduct 234 from 242 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 39

Moving on to step 6:
If we divide 88 by 39, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 7362.0
If we subtract 78 from 88, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 39, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 7362.2
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7362.25
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 7362.256
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 39, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 7362.2564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 7362.25641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 39, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7362.25641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 39 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 7362.2564102
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
39 goes into 220 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 7362.25641025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 7362.25641025 with a remainder of 2.5e-08.
