Let's divide 607998 by 78
We want to figure out the number of times 607998 can be divided by 78.

Going ahead to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 78

On to step 2:
60 divided by 78 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 78

On to step 3:
When dividing 607 by 78, we get 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 546 from 607, we get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 78

Going ahead to step 4:
The number 78 fits into 619 7 times, leaving a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we take 546 away from 619, we end up with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 78

Advancing to step 5:
If we divide 739 by 78, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 779.0
Subtract 702 from 739 to get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 78

Going ahead to step 6:
If we divide 378 by 78, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 7794.0
Subtract 312 from 378 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.

Going ahead to step 7:
If we divide 660 by 78, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 7794.8
Subtract 624 from 660 to 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.

Step 8:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7794.84
The remainder is 48 after subtracting 312 from 360.
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:
78 goes into 480 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7794.846
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.

Going ahead to step 10:
When dividing 120 by 78, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 7794.8461
Subtract 78 from 120 to get 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 11:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7794.84615
Deduct 390 from 420 and we're left 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.

Going ahead to step 12:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 7794.846153
Deduct 234 from 300 and we're left 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.

Let's proceed to step 13:
When dividing 660 by 78, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 7794.8461538
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.

On to step 14:
78 can be fit into 360 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7794.84615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 7794.84615384 with a remaining 4.8e-08.
