Let's divide 634724 by 78
We're looking to find how many times 78 goes into 634724.

Advancing to step 1:
78 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 78

On to step 2:
The number 78 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 78

Going ahead to step 3:
If we divide 634 by 78, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 624 from 634 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 78

Let's proceed to step 4:
107 divided by 78 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 78 away from 107, we end up with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 78

Let's proceed to step 5:
The number 78 fits into 292 3 times, leaving a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 813.0
If we subtract 234 from 292, we get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 78

Let's proceed to step 6:
78 can be fit into 584 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 8137.0
Subtracting 546 from 584 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
78 goes into 380 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 8137.4
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8137.48
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 8137.487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
78 goes into 140 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 8137.4871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
78 goes into 620 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 8137.48717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 8137.487179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 8137.4871794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 78 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8137.48717948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 8137.48717948 and a remainder of 5.6e-08.
