60777815 ÷ 78 
We want to figure out the number of times 60777815 can be divided by 78.

Let's proceed to step 1:
6 divided by 78 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 78

Step 2:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 78

Step 3:
78 goes into 607 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 546 from 607 and we're left with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 78

Moving on to step 4:
When dividing 617 by 78, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 546 from 617 to get 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 78

On to step 5:
78 can be fit into 717 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 779.0
The remainder is 15 after subtracting 702 from 717.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 78

Let's proceed to step 6:
The number 78 fits into 158 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 7792.0
Deduct 156 from 158 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 78

Advancing to step 7:
78 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 77920.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 78

On to step 8:
78 can be fit into 215 2 times, resulting in a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 779202.0
If we subtract 156 from 215, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
If we divide 590 by 78, we get 7 and a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 779202.7
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.

Moving on to step 10:
78 can be fit into 440 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 779202.75
If we subtract 390 from 440, we 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.

On to step 11:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 779202.756
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 78, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 779202.7564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 779202.75641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
When dividing 20 by 78, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 779202.75641
Deduct 0 from 20 and we're left with 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 15:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 779202.7564102
If we subtract 156 from 200, we 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.

Going ahead to step 16:
If we divide 440 by 78, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 779202.75641025
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.

Our division results in 779202.75641025 with a remaining 5e-08.
