We look at the division of 78103266 by 628 
We're looking to find how many times 628 goes into 78103266.

Let's proceed to step 1:
628 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 628

Advancing to step 2:
If we divide 78 by 628, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 628

Step 3:
If we divide 781 by 628, we get 1 and a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 628 from 781, we get 153.
Grab the next digit (0) from the dividend, add it to 153, then carry on: 1530 / 628

Let's proceed to step 4:
628 can be fit into 1530 2 times, resulting in a remainder of 274.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1256 from 1530 and we're left with 274.
Grab the next digit (3) from the dividend, add it to 274, then carry on: 2743 / 628

Step 5:
628 can be fit into 2743 4 times, resulting in a remainder of 231.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtract 2512 from 2743 to get 231.
Include the next digit (2) from the dividend after 231, then repeat: 2312 / 628

Let's proceed to step 6:
The number 628 fits into 2312 3 times, leaving a remainder of 428.
Record the quotient 3 as the next digit in the result. 
Result so far: 1243.0
If we take 1884 away from 2312, we end up with 428.
Include the next digit (6) from the dividend after 428, then repeat: 4286 / 628

Moving on to step 7:
628 goes into 4286 6 times with a remainder of 518.
Record the quotient 6 as the next digit in the result. 
Result so far: 12436.0
Subtract 3768 from 4286 to get 518.
Fetch the next digit (6) from the dividend, attach it to 518 and continue: 5186 / 628

Step 8:
The number 628 fits into 5186 8 times, leaving a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 124368.0
If we take 5024 away from 5186, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 9:
The number 628 fits into 1620 2 times, leaving a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 124368.2
Deduct 1256 from 1620 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 10:
3640 divided by 628 is 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 124368.25
Deduct 3140 from 3640 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 11:
If we divide 5000 by 628, we get 7 and a remainder of 604.
Use 7 as the next digit of our solution. 
Result so far: 124368.257
If we subtract 4396 from 5000, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 12:
628 can be fit into 6040 9 times, resulting in a remainder of 388.
Put 9 as the next digit of the answer. 
Result so far: 124368.2579
The remainder is 388 after subtracting 5652 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 13:
When dividing 3880 by 628, we get 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 124368.25796
The remainder is 112 after subtracting 3768 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
If we divide 1120 by 628, we get 1 and a remainder of 492.
The number 1 becomes the next digit in our result. 
Result so far: 124368.257961
If we subtract 628 from 1120, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 15:
628 goes into 4920 7 times with a remainder of 524.
The next digit of our result is 7. 
Result so far: 124368.2579617
If we take 4396 away from 4920, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 16:
628 can be fit into 5240 8 times, resulting in a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 124368.25796178
If we take 5024 away from 5240, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 124368.25796178 with a remainder of 2.16e-07.
