We look at the division of 375986 by 39 
Let's see how many times 39 fits into 375986.

Step 1:
The number 39 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 39

On to step 2:
When dividing 37 by 39, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 39

Let's proceed to step 3:
39 goes into 375 9 times with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 351 from 375 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 39

Let's proceed to step 4:
39 can be fit into 249 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 234 from 249, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 39

Let's proceed to step 5:
When dividing 158 by 39, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 964.0
Subtracting 156 from 158 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 39

Let's proceed to step 6:
The number 39 fits into 26 0 times, leaving a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 9640.0
If we subtract 0 from 26, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 39 fits into 260 6 times, leaving a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 9640.6
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
When dividing 260 by 39, we get 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 9640.66
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 9640.66 with a remaining 0.026.
