38786658 divided by 78 
We want to figure out the number of times 38786658 can be divided by 78.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Step 2:
When dividing 38 by 78, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 78

Moving on to step 3:
78 can be fit into 387 4 times, resulting in a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 312 away from 387, we end up with 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 78

Going ahead to step 4:
If we divide 758 by 78, we get 9 and a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 702 from 758 leaves us with 56.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 78

Going ahead to step 5:
78 can be fit into 566 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 497.0
Subtracting 546 from 566 leaves us with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 78

Let's proceed to step 6:
When dividing 206 by 78, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 4972.0
Deduct 156 from 206 and we're left with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 78

Step 7:
If we divide 505 by 78, we get 6 and a remainder of 37.
The next digit of our result is 6. 
Result so far: 49726.0
If we subtract 468 from 505, we get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 78

Advancing to step 8:
When dividing 378 by 78, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 497264.0
The remainder is 66 after subtracting 312 from 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 497264.8
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
When dividing 360 by 78, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 497264.84
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 497264.846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 497264.8461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 497264.84615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
300 divided by 78 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 497264.846153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 15:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 497264.8461538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
360 divided by 78 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 497264.84615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 497264.84615384 with a remaining 4.8e-08.
