458370 ÷ 78 
We want to divide 458370 by 78.

Let's proceed to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 78

Advancing to step 2:
45 divided by 78 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 78

Advancing to step 3:
When dividing 458 by 78, we get 5 with a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 390 from 458 to get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 78

Moving on to step 4:
The number 78 fits into 683 8 times, leaving a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
The remainder is 59 after subtracting 624 from 683.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 78

Moving on to step 5:
78 goes into 597 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 587.0
If we subtract 546 from 597, we get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 78

Step 6:
When dividing 510 by 78, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 5876.0
Deduct 468 from 510 and we're left 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.

Moving on to step 7:
78 goes into 420 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5876.5
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.

Step 8:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 5876.53
If we take 234 away from 300, we end up 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.

Going ahead to step 9:
If we divide 660 by 78, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 5876.538
The remainder is 36 after subtracting 624 from 660.
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 10:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 5876.5384
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.

Going ahead to step 11:
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: 5876.53846
If we take 468 away from 480, we end up with 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 12:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 5876.538461
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:
78 goes into 420 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5876.5384615
Subtracting 390 from 420 leaves us 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.

Advancing to step 14:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 5876.53846153
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.

After the division, we end up with 5876.53846153 and a remainder of 6.6e-08.
