Let's divide 561642 by 75
We're looking to find how many times 75 goes into 561642.

Step 1:
75 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 75

On to step 2:
When dividing 56 by 75, we get 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 75

On to step 3:
When dividing 561 by 75, we get 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 525 from 561 and we're left with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 75

Moving on to step 4:
75 can be fit into 366 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 300 from 366 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 75

Going ahead to step 5:
The number 75 fits into 664 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 748.0
Subtracting 600 from 664 leaves us with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 75

Advancing to step 6:
If we divide 642 by 75, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 7488.0
Deduct 600 from 642 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
420 divided by 75 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 7488.5
Subtracting 375 from 420 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 75, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 7488.56
Subtracting 450 from 450 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 75 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7488.56
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7488.56
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7488.56, with a leftover of 0.0.
