Let's divide 251560 by 78
We want to divide 251560 by 78.

Going ahead to step 1:
2 divided by 78 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 78

Step 2:
The number 78 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 78

Going ahead to step 3:
78 can be fit into 251 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 234 from 251, we get 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 78

On to step 4:
If we divide 175 by 78, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 156 from 175 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 78

Moving on to step 5:
78 goes into 196 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 322.0
If we take 156 away from 196, we end up with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 78

On to step 6:
If we divide 400 by 78, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3225.0
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 3225.1
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3225.12
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 78, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3225.128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 3225.1282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 78, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3225.1282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
78 goes into 400 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3225.128205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 3225.1282051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 3225.12820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 3225.12820512 with a balance of 6.4e-08.
