801442 ÷ 78 
We're looking to find how many times 78 goes into 801442.

Step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 78

Step 2:
80 divided by 78 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 80 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 78

Moving on to step 3:
21 divided by 78 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 78

Step 4:
When dividing 214 by 78, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 156 from 214 leaves us with 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 78

Advancing to step 5:
584 divided by 78 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1027.0
Subtracting 546 from 584 leaves us with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 78

Moving on to step 6:
78 goes into 382 4 times with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 10274.0
Subtract 312 from 382 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 10274.8
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
If we divide 760 by 78, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 10274.89
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
If we divide 580 by 78, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 10274.897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 10274.8974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 10274.89743
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 78, we get 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 10274.897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
78 goes into 700 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 10274.8974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
If we divide 760 by 78, we get 9 and a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 10274.89743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 10274.89743589 with a remainder of 5.8e-08.
