We're dividing 124571 by 78 
We want to figure out the number of times 124571 can be divided by 78.

Step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 78

Moving on to step 2:
When dividing 12 by 78, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 78

Advancing to step 3:
124 divided by 78 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 124 leaves us with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 78

Moving on to step 4:
When dividing 465 by 78, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 390 from 465 leaves us with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 78

Let's proceed to step 5:
78 goes into 757 9 times with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 702 away from 757, we end up with 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 78

Step 6:
78 can be fit into 551 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1597.0
If we subtract 546 from 551, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
78 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1597.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
If we divide 500 by 78, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1597.06
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1597.064
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
80 divided by 78 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1597.0641
The remainder is 2 after subtracting 78 from 80.
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 11:
If we divide 20 by 78, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1597.0641
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 12:
78 goes into 200 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1597.064102
Deduct 156 from 200 and we're left with 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 13:
440 divided by 78 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1597.0641025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
78 can be fit into 500 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1597.06410256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 1597.06410256 with a remaining 3.2e-08.
