992143 divided by 78 
We want to figure out the number of times 992143 can be divided by 78.

Moving on to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 78

Let's proceed to step 2:
99 divided by 78 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 21 after subtracting 78 from 99.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 78

Advancing to step 3:
78 can be fit into 212 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 156 from 212, we get 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 78

Let's proceed to step 4:
The number 78 fits into 561 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we subtract 546 from 561, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 78

Step 5:
When dividing 154 by 78, we get 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 1271.0
If we take 78 away from 154, we end up with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 78

Advancing to step 6:
78 can be fit into 763 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 12719.0
The remainder is 61 after subtracting 702 from 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
610 divided by 78 is 7 with a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 12719.7
The remainder is 64 after subtracting 546 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
640 divided by 78 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12719.78
The remainder is 16 after subtracting 624 from 640.
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 9:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12719.782
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.

Moving on to step 10:
40 divided by 78 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12719.782
Subtract 0 from 40 to get 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 11:
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: 12719.78205
Deduct 390 from 400 and we're left 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.

On to step 12:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 12719.782051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
78 goes into 220 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 12719.7820512
If we take 156 away from 220, we end up 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.

On to step 14:
When dividing 640 by 78, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12719.78205128
If we take 624 away from 640, we end up 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.

Our division results in 12719.78205128 with a remaining 1.6e-08.
