We look at the division of 305711 by 78 
We want to figure out the number of times 305711 can be divided by 78.

Advancing to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 78

Advancing to step 2:
78 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 78

Let's proceed to step 3:
78 can be fit into 305 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 234 from 305 and we're left with 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 78

Advancing to step 4:
717 divided by 78 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 702 from 717 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 78

Moving on to step 5:
78 goes into 151 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
The remainder is 73 after subtracting 78 from 151.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 78

Going ahead to step 6:
78 goes into 731 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 3919.0
Subtract 702 from 731 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
When dividing 290 by 78, we get 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 3919.3
Deduct 234 from 290 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
78 goes into 560 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 3919.37
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 3919.371
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
If we divide 620 by 78, we get 7 and a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 3919.3717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
78 goes into 740 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 3919.37179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 78, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 3919.371794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 3919.3717948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 3919.37179487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3919.37179487 with a remaining 1.4e-08.
