866150 ÷ 39 
Our goal is to divide 866150 by 39.

Going ahead to step 1:
When dividing 8 by 39, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 39

On to step 2:
When dividing 86 by 39, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 78 away from 86, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 39

Let's proceed to step 3:
39 can be fit into 86 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 78 from 86 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 39

Let's proceed to step 4:
The number 39 fits into 81 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 222.0
The remainder is 3 after subtracting 78 from 81.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 39

Step 5:
If we divide 35 by 39, we get 0 and a remainder of 35.
The next digit of our result is 0. 
Result so far: 2220.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 39

On to step 6:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 22208.0
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
39 goes into 380 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 22208.9
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 22208.97
Subtract 273 from 290 to 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.

Let's proceed to step 9:
If we divide 170 by 39, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 22208.974
Subtract 156 from 170 to 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 10:
39 goes into 140 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 22208.9743
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.

Let's proceed to step 11:
When dividing 230 by 39, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 22208.97435
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 12:
39 goes into 350 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 22208.974358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
When dividing 380 by 39, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 22208.9743589
If we take 351 away from 380, we end up 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.

Step 14:
If we divide 290 by 39, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 22208.97435897
Subtract 273 from 290 to 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.

After the division, we end up with 22208.97435897 and a remainder of 1.7e-08.
