We're dividing 78840247 by 392 
We want to figure out the number of times 78840247 can be divided by 392.

On to step 1:
If we divide 7 by 392, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 392

Step 2:
78 divided by 392 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 392

Advancing to step 3:
The number 392 fits into 788 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 784 away from 788, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 392

Going ahead to step 4:
When dividing 44 by 392, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 44 and we're left with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 392

Let's proceed to step 5:
When dividing 440 by 392, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 201.0
Subtract 392 from 440 to get 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 392

Moving on to step 6:
392 can be fit into 482 1 times, resulting in a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 2011.0
Subtract 392 from 482 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 392

Advancing to step 7:
904 divided by 392 is 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 20112.0
Subtract 784 from 904 to get 120.
Append the next digit (7) from the dividend to 120 and continue with: 1207 / 392

Going ahead to step 8:
The number 392 fits into 1207 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 201123.0
Subtract 1176 from 1207 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 392 fits into 310 0 times, leaving a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 201123.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
The number 392 fits into 3100 7 times, leaving a remainder of 356.
Use 7 as the next digit of our solution. 
Result so far: 201123.07
Subtract 2744 from 3100 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 11:
392 can be fit into 3560 9 times, resulting in a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 201123.079
Subtracting 3528 from 3560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
When dividing 320 by 392, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 201123.079
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
If we divide 3200 by 392, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 201123.07908
Deduct 3136 from 3200 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.

Let's proceed to step 14:
640 divided by 392 is 1 with a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 201123.079081
Subtract 392 from 640 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 15:
392 can be fit into 2480 6 times, resulting in a remainder of 128.
The next digit of our result is 6. 
Result so far: 201123.0790816
If we subtract 2352 from 2480, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
392 can be fit into 1280 3 times, resulting in a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 201123.07908163
If we take 1176 away from 1280, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 201123.07908163 with a remainder of 1.04e-07.
