We divide 634551 by 78
We're looking to find how many times 78 goes into 634551.

Going ahead to step 1:
78 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 78

Let's proceed to step 2:
When dividing 63 by 78, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 78

Moving on to step 3:
78 can be fit into 634 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 624 from 634 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 78

Advancing to step 4:
78 can be fit into 105 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 81.0
If we take 78 away from 105, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 78

On to step 5:
When dividing 275 by 78, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 813.0
If we take 234 away from 275, we end up with 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 78

Advancing to step 6:
If we divide 411 by 78, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 8135.0
Subtract 390 from 411 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
78 goes into 210 2 times with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 8135.2
Subtract 156 from 210 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
78 goes into 540 6 times with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 8135.26
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 8135.269
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
If we divide 180 by 78, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 8135.2692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 8135.26923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 78, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8135.26923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
When dividing 600 by 78, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 8135.2692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 8135.26923076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 8135.26923076, and the remainder is 7.2e-08.
