We look at the division of 836173 by 39 
Let's see how many times 39 fits into 836173.

Advancing to step 1:
The number 39 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 39

Moving on to step 2:
When dividing 83 by 39, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 78 from 83.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 39

Advancing to step 3:
When dividing 56 by 39, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 39 from 56 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 39

Going ahead to step 4:
When dividing 171 by 39, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Deduct 156 from 171 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 39

Moving on to step 5:
If we divide 157 by 39, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 2144.0
If we subtract 156 from 157, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 39

Advancing to step 6:
13 divided by 39 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 21440.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
39 can be fit into 130 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 21440.3
If we subtract 117 from 130, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
39 can be fit into 130 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 21440.33
If we subtract 117 from 130, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 21440.33, and the remainder is 0.013.
