We're dividing 64522087 by 78 
Let's see how many times 78 fits into 64522087.

Going ahead to step 1:
78 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 78

Going ahead to step 2:
The number 78 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 78

Going ahead to step 3:
78 can be fit into 645 8 times, resulting in a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 624 from 645 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 78

Going ahead to step 4:
When dividing 212 by 78, we get 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 156 from 212 and we're left with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 78

Advancing to step 5:
If we divide 562 by 78, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 827.0
If we subtract 546 from 562, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 78

Step 6:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8272.0
If we subtract 156 from 160, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 78

Advancing to step 7:
The number 78 fits into 48 0 times, leaving a remainder of 48.
The next digit of our result is 0. 
Result so far: 82720.0
The remainder is 48 after subtracting 0 from 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 78

Moving on to step 8:
487 divided by 78 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 827206.0
If we subtract 468 from 487, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
If we divide 190 by 78, we get 2 and a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 827206.2
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 78 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 827206.24
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 827206.243
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 78, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 827206.2435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 827206.24358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 827206.243589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 15:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 827206.2435897
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 16:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 827206.24358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 827206.24358974, with a leftover of 2.8e-08.
