We're dividing 809810 by 78 
Our goal is to divide 809810 by 78.

Going ahead to step 1:
78 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 78

Advancing to step 2:
78 can be fit into 80 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 78 from 80.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 78

Going ahead to step 3:
29 divided by 78 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 78

On to step 4:
298 divided by 78 is 3 with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtracting 234 from 298 leaves us with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 78

On to step 5:
78 can be fit into 641 8 times, resulting in a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 1038.0
The remainder is 17 after subtracting 624 from 641.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 78

Step 6:
78 goes into 170 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 10382.0
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 78 is 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 10382.1
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
620 divided by 78 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 10382.17
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
740 divided by 78 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 10382.179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 10382.1794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
78 can be fit into 680 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 10382.17948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
560 divided by 78 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 10382.179487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
78 goes into 140 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 10382.1794871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 10382.17948717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 10382.17948717 and a remainder of 7.4e-08.
