We divide 78928026 by 123
We want to divide 78928026 by 123.

Going ahead to step 1:
When dividing 7 by 123, we get 0 with 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 123

Let's proceed to step 2:
78 divided by 123 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 123

On to step 3:
When dividing 789 by 123, we get 6 with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 51 after subtracting 738 from 789.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 123

Let's proceed to step 4:
The number 123 fits into 512 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 492 from 512 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 123

Advancing to step 5:
123 can be fit into 208 1 times, resulting in a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 641.0
Subtracting 123 from 208 leaves us with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 123

Step 6:
The number 123 fits into 850 6 times, leaving a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 6416.0
The remainder is 112 after subtracting 738 from 850.
Grab the next digit (2) from the dividend, add it to 112, then carry on: 1122 / 123

Let's proceed to step 7:
1122 divided by 123 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 64169.0
If we subtract 1107 from 1122, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 123

On to step 8:
123 goes into 156 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 641691.0
Subtract 123 from 156 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
If we divide 330 by 123, we get 2 and a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 641691.2
If we take 246 away from 330, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
840 divided by 123 is 6 with a remainder of 102.
The next digit of our result is 6. 
Result so far: 641691.26
Subtracting 738 from 840 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 11:
123 can be fit into 1020 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 641691.268
Deduct 984 from 1020 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 123 is 2 with a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 641691.2682
Deduct 246 from 360 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 13:
When dividing 1140 by 123, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 641691.26829
If we subtract 1107 from 1140, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 14:
If we divide 330 by 123, we get 2 and a remainder of 84.
The next digit of our result is 2. 
Result so far: 641691.268292
Subtract 246 from 330 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
123 can be fit into 840 6 times, resulting in a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 641691.2682926
If we take 738 away from 840, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 16:
123 can be fit into 1020 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 641691.26829268
If we subtract 984 from 1020, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 641691.26829268 with a remainder of 3.6e-08.
