Let's divide 621719 by 75
We're looking to find how many times 75 goes into 621719.

Step 1:
75 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 75

Let's proceed to step 2:
When dividing 62 by 75, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 75

Advancing to step 3:
75 can be fit into 621 8 times, resulting in a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 21 after subtracting 600 from 621.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 75

On to step 4:
75 can be fit into 217 2 times, resulting in a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
The remainder is 67 after subtracting 150 from 217.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 75

On to step 5:
When dividing 671 by 75, we get 8 with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 828.0
Subtracting 600 from 671 leaves us with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 75

Let's proceed to step 6:
75 goes into 719 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 8289.0
Deduct 675 from 719 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
440 divided by 75 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 8289.5
Subtracting 375 from 440 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
The number 75 fits into 650 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 8289.58
If we subtract 600 from 650, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 8289.586
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 8289.5866
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8289.5866, with a leftover of 0.0005.
