We look at the division of 70578 by 78 
We want to figure out the number of times 70578 can be divided by 78.

Moving on to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 78

Going ahead to step 2:
When dividing 70 by 78, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 78

Moving on to step 3:
78 goes into 705 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 3 after subtracting 702 from 705.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 78

Let's proceed to step 4:
78 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 37, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 78

On to step 5:
78 can be fit into 378 4 times, resulting in a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 904.0
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.

Moving on to step 6:
78 goes into 660 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 904.8
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.

Let's proceed to step 7:
78 goes into 360 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 904.84
Deduct 312 from 360 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.

Let's proceed to step 8:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 904.846
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:
When dividing 120 by 78, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 904.8461
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 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: 904.84615
If we take 390 away from 420, we end up 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 11:
The number 78 fits into 300 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 904.846153
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.

On to step 12:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 904.8461538
If we subtract 624 from 660, we 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.

On to step 13:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 904.84615384
Subtracting 312 from 360 leaves us 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.

After the division, we end up with 904.84615384 and a remainder of 4.8e-08.
