Let's divide 64498790 by 78
We want to divide 64498790 by 78.

Advancing to step 1:
78 can be fit into 6 0 times, resulting in 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.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 78

Let's proceed to step 2:
The number 78 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 78

Moving on to step 3:
When dividing 644 by 78, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 624 from 644 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 78

Moving on to step 4:
If we divide 209 by 78, we get 2 and a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 156 from 209, we get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 78

Advancing to step 5:
When dividing 538 by 78, we get 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
If we take 468 away from 538, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 78

Step 6:
The number 78 fits into 707 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 8269.0
Subtracting 702 from 707 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 78

Going ahead to step 7:
When dividing 59 by 78, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 82690.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 78

Moving on to step 8:
590 divided by 78 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 826907.0
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 826907.5
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 826907.56
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 826907.564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 78, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 826907.5641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
78 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 826907.5641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 826907.564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 15:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 826907.5641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 826907.56410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 826907.56410256, and the remainder is 3.2e-08.
