43984213 ÷ 173 
We want to figure out the number of times 43984213 can be divided by 173.

Moving on to step 1:
If we divide 4 by 173, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 173

Advancing to step 2:
173 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 173

Moving on to step 3:
If we divide 439 by 173, we get 2 and a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 346 from 439, we get 93.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 173

On to step 4:
173 goes into 938 5 times with a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 865 from 938, we get 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 173

On to step 5:
The number 173 fits into 734 4 times, leaving a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Deduct 692 from 734 and we're left with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 173

Going ahead to step 6:
422 divided by 173 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 2542.0
If we take 346 away from 422, we end up with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 173

Let's proceed to step 7:
173 can be fit into 761 4 times, resulting in a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 25424.0
If we take 692 away from 761, we end up with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 173

Let's proceed to step 8:
When dividing 693 by 173, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 254244.0
Deduct 692 from 693 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.

Going ahead to step 9:
The number 173 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 254244.0
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.

Going ahead to step 10:
100 divided by 173 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 254244.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 254244.0 with a remaining 0.1.
