391684 divided by 10 
We want to divide 391684 by 10.

Step 1:
If we divide 3 by 10, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 10

On to step 2:
10 can be fit into 39 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 30 from 39 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 10

Let's proceed to step 3:
10 can be fit into 91 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 90 away from 91, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 10

Step 4:
When dividing 16 by 10, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 391.0
If we subtract 10 from 16, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 10

Let's proceed to step 5:
68 divided by 10 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3916.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 10

Moving on to step 6:
The number 10 fits into 84 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 39168.0
Subtracting 80 from 84 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 10, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 39168.4
If we take 40 away from 40, we end up 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.

Going ahead to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39168.4
Deduct 0 from 0 and we're left 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 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39168.4
The remainder is 0 after subtracting 0 from 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 final outcome is 39168.4, with a leftover of 0.0.
