We look at the division of 43008197 by 321 
We're looking to find how many times 321 goes into 43008197.

Moving on to step 1:
4 divided by 321 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 321

Advancing to step 2:
321 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
If we subtract 0 from 43, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 321

Advancing to step 3:
When dividing 430 by 321, we get 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 321 from 430 leaves us with 109.
Take the next digit (0) from the dividend and append it to 109, then repeat: 1090 / 321

Moving on to step 4:
321 can be fit into 1090 3 times, resulting in a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 963 from 1090 to get 127.
Grab the next digit (8) from the dividend, add it to 127, then carry on: 1278 / 321

Moving on to step 5:
321 can be fit into 1278 3 times, resulting in a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 963 from 1278 leaves us with 315.
Include the next digit (1) from the dividend after 315, then repeat: 3151 / 321

Advancing to step 6:
321 can be fit into 3151 9 times, resulting in a remainder of 262.
Put 9 as the next digit of the answer. 
Result so far: 1339.0
Deduct 2889 from 3151 and we're left with 262.
Take the next digit (9) from the dividend and append it to 262, then repeat: 2629 / 321

Advancing to step 7:
If we divide 2629 by 321, we get 8 and a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 13398.0
The remainder is 61 after subtracting 2568 from 2629.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 321

Going ahead to step 8:
If we divide 617 by 321, we get 1 and a remainder of 296.
The next digit of our result is 1. 
Result so far: 133981.0
The remainder is 296 after subtracting 321 from 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
321 goes into 2960 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 133981.9
Subtracting 2889 from 2960 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
When dividing 710 by 321, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 133981.92
Subtracting 642 from 710 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
The number 321 fits into 680 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 133981.922
Deduct 642 from 680 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 133981.922 and a remainder of 0.0038.
