Let's divide 78129017 by 634
We want to divide 78129017 by 634.

Let's proceed to step 1:
If we divide 7 by 634, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 634

Going ahead to step 2:
If we divide 78 by 634, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 634

On to step 3:
The number 634 fits into 781 1 times, leaving a remainder of 147.
The next digit of our result is 1. 
Result so far: 1.0
If we take 634 away from 781, we end up with 147.
Fetch the next digit (2) from the dividend, attach it to 147 and continue: 1472 / 634

Advancing to step 4:
When dividing 1472 by 634, we get 2 with a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1268 away from 1472, we end up with 204.
Include the next digit (9) from the dividend after 204, then repeat: 2049 / 634

Step 5:
When dividing 2049 by 634, we get 3 with a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 1902 from 2049 and we're left with 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 634

On to step 6:
1470 divided by 634 is 2 with a remainder of 202.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
The remainder is 202 after subtracting 1268 from 1470.
Take the next digit (1) from the dividend and append it to 202, then repeat: 2021 / 634

On to step 7:
634 goes into 2021 3 times with a remainder of 119.
The next digit of our result is 3. 
Result so far: 12323.0
Subtract 1902 from 2021 to get 119.
Grab the next digit (7) from the dividend, add it to 119, then carry on: 1197 / 634

Moving on to step 8:
1197 divided by 634 is 1 with a remainder of 563.
Put 1 as the next digit of the answer. 
Result so far: 123231.0
If we take 634 away from 1197, we end up with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Step 9:
634 can be fit into 5630 8 times, resulting in a remainder of 558.
The number 8 becomes the next digit in our result. 
Result so far: 123231.8
If we take 5072 away from 5630, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 10:
If we divide 5580 by 634, we get 8 and a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 123231.88
The remainder is 508 after subtracting 5072 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Our division results in 123231.88 with a remaining 0.508.
