We divide 552121 by 78
We're looking to find how many times 78 goes into 552121.

On to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 78

Step 2:
The number 78 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 78

Step 3:
If we divide 552 by 78, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 546 from 552, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 78

Let's proceed to step 4:
78 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 61 to get 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 78

Let's proceed to step 5:
78 can be fit into 612 7 times, resulting in a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 707.0
Subtract 546 from 612 to get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 78

Advancing to step 6:
When dividing 661 by 78, we get 8 with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 7078.0
The remainder is 37 after subtracting 624 from 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 78, we get 4 and a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 7078.4
Subtracting 312 from 370 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.

Step 8:
If we divide 580 by 78, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 7078.47
Deduct 546 from 580 and we're left 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 9:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 7078.474
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 7078.4743
Subtracting 234 from 280 leaves us 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.

Step 11:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 7078.47435
The remainder is 70 after subtracting 390 from 460.
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 12:
If we divide 700 by 78, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 7078.474358
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.

Going ahead to step 13:
When dividing 760 by 78, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 7078.4743589
The remainder is 58 after subtracting 702 from 760.
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 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7078.47435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 7078.47435897 with a balance of 3.4e-08.
