Let's divide 763641 by 78
We want to figure out the number of times 763641 can be divided by 78.

Let's proceed to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 78

Let's proceed to step 2:
When dividing 76 by 78, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 78

Advancing to step 3:
The number 78 fits into 763 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 702 from 763 and we're left with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 78

Advancing to step 4:
78 goes into 616 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 546 from 616 to get 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 78

Advancing to step 5:
78 goes into 704 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 979.0
The remainder is 2 after subtracting 702 from 704.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 78

Step 6:
The number 78 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 9790.0
Subtracting 0 from 21 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 78 is 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 9790.2
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.

Let's proceed to step 8:
540 divided by 78 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 9790.26
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 78, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9790.269
If we subtract 702 from 720, we 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:
180 divided by 78 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9790.2692
If we take 156 away from 180, we end up with 24.
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:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 9790.26923
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.

Let's proceed to step 12:
60 divided by 78 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9790.26923
Subtract 0 from 60 to get 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:
78 goes into 600 7 times with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 9790.2692307
Subtracting 546 from 600 leaves us 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 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 9790.26923076
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.

After the division, we end up with 9790.26923076 and a remainder of 7.2e-08.
