819634 divided by 78 
We're looking to find how many times 78 goes into 819634.

On to step 1:
8 divided by 78 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 78

Let's proceed to step 2:
78 can be fit into 81 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 78 from 81.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 78

Moving on to step 3:
When dividing 39 by 78, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 39, we end up with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 78

Going ahead to step 4:
396 divided by 78 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
The remainder is 6 after subtracting 390 from 396.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 78

Going ahead to step 5:
The number 78 fits into 63 0 times, leaving a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 1050.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 78

On to step 6:
The number 78 fits into 634 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 10508.0
Subtract 624 from 634 to 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.

Step 7:
78 goes into 100 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10508.1
Subtracting 78 from 100 leaves us 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.

Step 8:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 10508.12
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 9:
If we divide 640 by 78, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10508.128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10508.1282
If we take 156 away from 160, we end up 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.

Moving on to step 11:
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: 10508.1282
If we take 0 away from 40, we end up 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 12:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10508.128205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
78 goes into 100 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10508.1282051
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.

Going ahead to step 14:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10508.12820512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 10508.12820512 with a remainder of 6.4e-08.
