Let's divide 615220 by 78
We want to divide 615220 by 78.

Moving on to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 78

Let's proceed to step 2:
78 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 78

Going ahead to step 3:
If we divide 615 by 78, we get 7 and a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 69 after subtracting 546 from 615.
Take the next digit (2) from the dividend and append it to 69, then repeat: 692 / 78

Step 4:
692 divided by 78 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 624 from 692 and we're left with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 78

Let's proceed to step 5:
When dividing 682 by 78, we get 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 788.0
Subtract 624 from 682 to get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 78

Going ahead to step 6:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7887.0
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 7887.4
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 7887.43
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
78 goes into 460 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7887.435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
700 divided by 78 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 7887.4358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 7887.43589
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7887.435897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 7887.4358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
If we divide 280 by 78, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 7887.43589743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 7887.43589743, and the remainder is 4.6e-08.
