We look at the division of 39735973 by 789 
Let's see how many times 789 fits into 39735973.

Let's proceed to step 1:
When dividing 3 by 789, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 789

On to step 2:
When dividing 39 by 789, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 789

On to step 3:
397 divided by 789 is 0 with a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Take the next digit (3) from the dividend and append it to 397, then repeat: 3973 / 789

Let's proceed to step 4:
3973 divided by 789 is 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3945 from 3973, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 789

Let's proceed to step 5:
The number 789 fits into 285 0 times, leaving a remainder of 285.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we take 0 away from 285, we end up with 285.
Include the next digit (9) from the dividend after 285, then repeat: 2859 / 789

Going ahead to step 6:
789 can be fit into 2859 3 times, resulting in a remainder of 492.
The next digit of our result is 3. 
Result so far: 503.0
The remainder is 492 after subtracting 2367 from 2859.
Include the next digit (7) from the dividend after 492, then repeat: 4927 / 789

Step 7:
When dividing 4927 by 789, we get 6 with a remainder of 193.
Put 6 as the next digit of the answer. 
Result so far: 5036.0
Deduct 4734 from 4927 and we're left with 193.
Fetch the next digit (3) from the dividend, attach it to 193 and continue: 1933 / 789

Moving on to step 8:
If we divide 1933 by 789, we get 2 and a remainder of 355.
Use 2 as the next digit of our solution. 
Result so far: 50362.0
The remainder is 355 after subtracting 1578 from 1933.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 9:
When dividing 3550 by 789, we get 4 with a remainder of 394.
Put 4 as the next digit of the answer. 
Result so far: 50362.4
Deduct 3156 from 3550 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 10:
If we divide 3940 by 789, we get 4 and a remainder of 784.
Write down 4 as next digit of the result. 
Result so far: 50362.44
If we subtract 3156 from 3940, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

The quotient of the division is 50362.44, and the remainder is 0.784.
