Let's divide 816520 by 78
Our goal is to divide 816520 by 78.

Moving on to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 78

Step 2:
The number 78 fits into 81 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 81 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 78

Moving on to step 3:
36 divided by 78 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 36, we end up with 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 78

Moving on to step 4:
78 goes into 365 4 times with a remainder of 53.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 312 from 365 and we're left with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 78

Moving on to step 5:
If we divide 532 by 78, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 1046.0
The remainder is 64 after subtracting 468 from 532.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 78

On to step 6:
When dividing 640 by 78, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10468.0
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 10468.2
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 78, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10468.2
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10468.205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 10468.2051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
220 divided by 78 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 10468.20512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
640 divided by 78 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 10468.205128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10468.2051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10468.2051282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 10468.2051282 with a remaining 4e-08.
