We're dividing 78634 by 75 
Let's see how many times 75 fits into 78634.

On to step 1:
75 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 75

Advancing to step 2:
When dividing 78 by 75, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 75 from 78 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 75

Let's proceed to step 3:
75 goes into 36 0 times with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 75

Let's proceed to step 4:
When dividing 363 by 75, we get 4 with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 300 away from 363, we end up with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 75

Advancing to step 5:
When dividing 634 by 75, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1048.0
Subtracting 600 from 634 leaves us 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.

Let's proceed to step 6:
If we divide 340 by 75, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1048.4
Subtracting 300 from 340 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.

Let's proceed to step 7:
The number 75 fits into 400 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1048.45
The remainder is 25 after subtracting 375 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 1048.453
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 1048.4533
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 1048.4533, and the remainder is 0.00025.
