Let's divide 43978 by 53
We want to figure out the number of times 43978 can be divided by 53.

Step 1:
When dividing 4 by 53, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 53

Moving on to step 2:
53 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 53

On to step 3:
53 can be fit into 439 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 424 from 439 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 53

On to step 4:
53 goes into 157 2 times with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 51 after subtracting 106 from 157.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 53

Going ahead to step 5:
53 can be fit into 518 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 829.0
If we take 477 away from 518, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 6:
53 goes into 410 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 829.7
Subtract 371 from 410 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
53 can be fit into 390 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 829.77
If we take 371 away from 390, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 829.77, and the remainder is 0.019.
