Let's divide 748251 by 78
Our goal is to divide 748251 by 78.

Advancing to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 78

Step 2:
78 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 78

On to step 3:
78 can be fit into 748 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 702 from 748 and we're left with 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 78

On to step 4:
78 goes into 462 5 times with a remainder of 72.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 72 after subtracting 390 from 462.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 78

Let's proceed to step 5:
78 can be fit into 725 9 times, resulting in a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 959.0
The remainder is 23 after subtracting 702 from 725.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 78

On to step 6:
231 divided by 78 is 2 with a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 9592.0
Subtracting 156 from 231 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
750 divided by 78 is 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 9592.9
Deduct 702 from 750 and we're left with 48.
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 8:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 9592.96
Deduct 468 from 480 and we're left 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 9:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 9592.961
If we take 78 away from 120, we end up 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.

On to step 10:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 9592.9615
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.

Moving on to step 11:
If we divide 300 by 78, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 9592.96153
Subtracting 234 from 300 leaves us 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.

Step 12:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9592.961538
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 13:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 9592.9615384
Subtract 312 from 360 to 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.

Advancing to step 14:
78 goes into 480 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 9592.96153846
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.

The final result is 9592.96153846 with a remainder of 1.2e-08.
