We're looking to find how many times 398 goes into 43052986.

Step 1:
When dividing 4 by 398, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 398

Going ahead to step 2:
398 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 398

Going ahead to step 3:
When dividing 430 by 398, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 32 after subtracting 398 from 430.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 398

Let's proceed to step 4:
398 goes into 325 0 times with a remainder of 325.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 325 to get 325.
Take the next digit (2) from the dividend and append it to 325, then repeat: 3252 / 398

Going ahead to step 5:
The number 398 fits into 3252 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 3184 from 3252 leaves us with 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 398

On to step 6:
When dividing 689 by 398, we get 1 with a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 1081.0
Subtract 398 from 689 to get 291.
Fetch the next digit (8) from the dividend, attach it to 291 and continue: 2918 / 398

Moving on to step 7:
398 goes into 2918 7 times with a remainder of 132.
The next digit of our result is 7. 
Result so far: 10817.0
Subtract 2786 from 2918 to get 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 398

Moving on to step 8:
398 can be fit into 1326 3 times, resulting in a remainder of 132.
The next digit of our result is 3. 
Result so far: 108173.0
Subtracting 1194 from 1326 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
When dividing 1320 by 398, we get 3 with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 108173.3
If we subtract 1194 from 1320, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
398 goes into 1260 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 108173.33
The remainder is 66 after subtracting 1194 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 108173.33 with a remaining 0.066.
