We're dividing 51448751 by 815 
Let's see how many times 815 fits into 51448751.

On to step 1:
5 divided by 815 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 815

Let's proceed to step 2:
If we divide 51 by 815, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 815

Let's proceed to step 3:
514 divided by 815 is 0 with a remainder of 514.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 514 leaves us with 514.
Take the next digit (4) from the dividend and append it to 514, then repeat: 5144 / 815

Step 4:
If we divide 5144 by 815, we get 6 and a remainder of 254.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4890 from 5144 and we're left with 254.
Bring next digit (8) of the dividend behind the 254 and repeat the process: 2548 / 815

On to step 5:
815 goes into 2548 3 times with a remainder of 103.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 2445 from 2548 to get 103.
Take the next digit (7) from the dividend and append it to 103, then repeat: 1037 / 815

Let's proceed to step 6:
815 can be fit into 1037 1 times, resulting in a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 631.0
The remainder is 222 after subtracting 815 from 1037.
Take the next digit (5) from the dividend and append it to 222, then repeat: 2225 / 815

Going ahead to step 7:
815 goes into 2225 2 times with a remainder of 595.
The number 2 becomes the next digit in our result. 
Result so far: 6312.0
If we subtract 1630 from 2225, we get 595.
Grab the next digit (1) from the dividend, add it to 595, then carry on: 5951 / 815

Let's proceed to step 8:
If we divide 5951 by 815, we get 7 and a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 63127.0
If we subtract 5705 from 5951, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 9:
If we divide 2460 by 815, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 63127.3
Subtract 2445 from 2460 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
815 goes into 150 0 times with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 63127.3
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
815 goes into 1500 1 times with a remainder of 685.
The next digit of our result is 1. 
Result so far: 63127.301
Subtract 815 from 1500 to get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 12:
815 can be fit into 6850 8 times, resulting in a remainder of 330.
Record the quotient 8 as the next digit in the result. 
Result so far: 63127.3018
Subtract 6520 from 6850 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 13:
815 can be fit into 3300 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 63127.30184
The remainder is 40 after subtracting 3260 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
400 divided by 815 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 63127.30184
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
When dividing 4000 by 815, we get 4 with a remainder of 740.
Use 4 as the next digit of our solution. 
Result so far: 63127.3018404
Subtracting 3260 from 4000 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 16:
When dividing 7400 by 815, we get 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 63127.30184049
Deduct 7335 from 7400 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 63127.30184049 with a remaining 6.5e-08.
