Let's divide 54663185 by 813
Our goal is to divide 54663185 by 813.

On to step 1:
813 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 813

Let's proceed to step 2:
If we divide 54 by 813, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 813

Going ahead to step 3:
If we divide 546 by 813, we get 0 and a remainder of 546.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 546, we get 546.
Grab the next digit (6) from the dividend, add it to 546, then carry on: 5466 / 813

Going ahead to step 4:
813 can be fit into 5466 6 times, resulting in a remainder of 588.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 4878 from 5466, we get 588.
Fetch the next digit (3) from the dividend, attach it to 588 and continue: 5883 / 813

On to step 5:
813 can be fit into 5883 7 times, resulting in a remainder of 192.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 5691 from 5883 and we're left with 192.
Include the next digit (1) from the dividend after 192, then repeat: 1921 / 813

Step 6:
The number 813 fits into 1921 2 times, leaving a remainder of 295.
The next digit of our result is 2. 
Result so far: 672.0
Subtract 1626 from 1921 to get 295.
Take the next digit (8) from the dividend and append it to 295, then repeat: 2958 / 813

On to step 7:
The number 813 fits into 2958 3 times, leaving a remainder of 519.
The next digit of our result is 3. 
Result so far: 6723.0
If we subtract 2439 from 2958, we get 519.
Take the next digit (5) from the dividend and append it to 519, then repeat: 5195 / 813

Going ahead to step 8:
5195 divided by 813 is 6 with a remainder of 317.
Record the quotient 6 as the next digit in the result. 
Result so far: 67236.0
If we subtract 4878 from 5195, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
When dividing 3170 by 813, we get 3 with a remainder of 731.
The number 3 becomes the next digit in our result. 
Result so far: 67236.3
If we take 2439 away from 3170, we end up with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Going ahead to step 10:
7310 divided by 813 is 8 with a remainder of 806.
Record the quotient 8 as the next digit in the result. 
Result so far: 67236.38
If we subtract 6504 from 7310, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

On to step 11:
813 goes into 8060 9 times with a remainder of 743.
Record the quotient 9 as the next digit in the result. 
Result so far: 67236.389
The remainder is 743 after subtracting 7317 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

On to step 12:
If we divide 7430 by 813, we get 9 and a remainder of 113.
The next digit of our result is 9. 
Result so far: 67236.3899
If we subtract 7317 from 7430, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The quotient of the division is 67236.3899, and the remainder is 0.00113.
