816820 divided by 78 
We're looking to find how many times 78 goes into 816820.

Let's proceed to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 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.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 78 away from 81, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

Moving on to step 3:
36 divided by 78 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 78

Going ahead to step 4:
When dividing 368 by 78, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 56 after subtracting 312 from 368.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 78

Advancing to step 5:
When dividing 562 by 78, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1047.0
Deduct 546 from 562 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 78

On to step 6:
When dividing 160 by 78, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10472.0
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.

Step 7:
When dividing 40 by 78, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10472.0
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.

Moving on to step 8:
When dividing 400 by 78, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 10472.05
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.

Advancing to step 9:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10472.051
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.

Moving on to step 10:
If we divide 220 by 78, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 10472.0512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
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: 10472.05128
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.

Advancing to step 12:
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: 10472.051282
Subtract 156 from 160 to 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.

Step 13:
When dividing 40 by 78, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10472.051282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10472.05128205
Subtract 390 from 400 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.

The final outcome is 10472.05128205, with a leftover of 1e-08.
