We're dividing 78357546 by 810 
Let's see how many times 810 fits into 78357546.

Let's proceed to step 1:
810 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 810

Let's proceed to step 2:
The number 810 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 810

Moving on to step 3:
When dividing 783 by 810, we get 0 with a remainder of 783.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 783, we get 783.
Fetch the next digit (5) from the dividend, attach it to 783 and continue: 7835 / 810

Step 4:
810 can be fit into 7835 9 times, resulting in a remainder of 545.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7290 from 7835 to get 545.
Append the next digit (7) from the dividend to 545 and continue with: 5457 / 810

On to step 5:
When dividing 5457 by 810, we get 6 with a remainder of 597.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 4860 from 5457, we get 597.
Take the next digit (5) from the dividend and append it to 597, then repeat: 5975 / 810

Advancing to step 6:
If we divide 5975 by 810, we get 7 and a remainder of 305.
Put 7 as the next digit of the answer. 
Result so far: 967.0
If we subtract 5670 from 5975, we get 305.
Include the next digit (4) from the dividend after 305, then repeat: 3054 / 810

Step 7:
When dividing 3054 by 810, we get 3 with a remainder of 624.
Write down 3 as next digit of the result. 
Result so far: 9673.0
If we take 2430 away from 3054, we end up with 624.
Take the next digit (6) from the dividend and append it to 624, then repeat: 6246 / 810

Moving on to step 8:
When dividing 6246 by 810, we get 7 with a remainder of 576.
Use 7 as the next digit of our solution. 
Result so far: 96737.0
Subtract 5670 from 6246 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 9:
If we divide 5760 by 810, we get 7 and a remainder of 90.
The number 7 becomes the next digit in our result. 
Result so far: 96737.7
The remainder is 90 after subtracting 5670 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
810 can be fit into 900 1 times, resulting in a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 96737.71
If we take 810 away from 900, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
The number 810 fits into 900 1 times, leaving a remainder of 90.
The next digit of our result is 1. 
Result so far: 96737.711
Deduct 810 from 900 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 96737.711 with a remaining 0.009.
