321958 ÷ 43 
We want to figure out the number of times 321958 can be divided by 43.

On to step 1:
3 divided by 43 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 43

Advancing to step 2:
The number 43 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 43

Moving on to step 3:
The number 43 fits into 321 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 301 from 321, we get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

Let's proceed to step 4:
When dividing 209 by 43, we get 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 172 from 209 leaves us with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 43

Going ahead to step 5:
When dividing 375 by 43, we get 8 with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 748.0
Subtracting 344 from 375 leaves us with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 43

On to step 6:
When dividing 318 by 43, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7487.0
The remainder is 17 after subtracting 301 from 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 43 fits into 170 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 7487.3
If we take 129 away from 170, 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.

Advancing to step 8:
The number 43 fits into 410 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 7487.39
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
230 divided by 43 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7487.395
If we subtract 215 from 230, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
43 goes into 150 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 7487.3953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 7487.39534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 43, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 7487.395348
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 43, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7487.3953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 7487.3953488 with a balance of 1.6e-07.
