We're dividing 334257 by 78 
Let's see how many times 78 fits into 334257.

Moving on to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 78

Advancing to step 2:
If we divide 33 by 78, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 78

Moving on to step 3:
The number 78 fits into 334 4 times, leaving a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 312 from 334, we get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 78

On to step 4:
78 goes into 222 2 times with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 156 from 222 to get 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 78

Going ahead to step 5:
78 can be fit into 665 8 times, resulting in a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 428.0
The remainder is 41 after subtracting 624 from 665.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 78

Going ahead to step 6:
When dividing 417 by 78, we get 5 with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 4285.0
Subtract 390 from 417 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
The number 78 fits into 270 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 4285.3
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 4285.34
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.

On to step 9:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 4285.346
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 4285.3461
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.

On to step 11:
When dividing 420 by 78, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4285.34615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 4285.346153
Subtracting 234 from 300 leaves us with 66.
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 13:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 4285.3461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4285.34615384
Subtracting 312 from 360 leaves us 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.

The final result is 4285.34615384 with a remainder of 4.8e-08.
