We divide 684451 by 75
Our goal is to divide 684451 by 75.

Going ahead to step 1:
75 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 75

Step 2:
75 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 75

Step 3:
75 goes into 684 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 675 from 684 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 75

On to step 4:
When dividing 94 by 75, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we take 75 away from 94, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 75

Moving on to step 5:
75 goes into 195 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 912.0
Subtract 150 from 195 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 75

Moving on to step 6:
If we divide 451 by 75, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 9126.0
Subtracting 450 from 451 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
75 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 9126.0
Deduct 0 from 10 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.

Moving on to step 8:
The number 75 fits into 100 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 9126.01
Subtracting 75 from 100 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 9126.013
Subtracting 225 from 250 leaves us with 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 10:
75 goes into 250 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9126.0133
If we take 225 away from 250, we end up with 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 9126.0133, and the remainder is 0.00025.
