75645 divided by 4 
We want to divide 75645 by 4.

On to step 1:
When dividing 7 by 4, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 4 away from 7, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

On to step 2:
4 can be fit into 35 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 3 after subtracting 32 from 35.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

Going ahead to step 3:
When dividing 36 by 4, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 189.0
If we take 36 away from 36, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Going ahead to step 4:
4 goes into 4 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1891.0
Deduct 4 from 4 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 4

Advancing to step 5:
The number 4 fits into 5 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 18911.0
Deduct 4 from 5 and we're left 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 6:
10 divided by 4 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 18911.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 18911.25
Subtracting 20 from 20 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 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18911.25
Subtract 0 from 0 to get 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 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18911.25
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 18911.25 with a balance of 0.0.
