439217 divided by 91 
We want to figure out the number of times 439217 can be divided by 91.

Moving on to step 1:
The number 91 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 91

Moving on to step 2:
If we divide 43 by 91, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 91

On to step 3:
91 goes into 439 4 times with a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 364 from 439 to get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 91

Going ahead to step 4:
When dividing 752 by 91, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 728 from 752 leaves us with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 91

Moving on to step 5:
91 goes into 241 2 times with a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 482.0
Subtract 182 from 241 to get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 91

Moving on to step 6:
The number 91 fits into 597 6 times, leaving a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 4826.0
Subtracting 546 from 597 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
91 goes into 510 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4826.5
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
When dividing 550 by 91, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4826.56
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
91 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4826.56
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 91, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4826.5604
If we take 364 away from 400, we end up 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 11:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 4826.56043
If we subtract 273 from 360, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 12:
91 goes into 870 9 times with a remainder of 51.
The next digit of our result is 9. 
Result so far: 4826.560439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
91 goes into 510 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 4826.5604395
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
91 can be fit into 550 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4826.56043956
Deduct 546 from 550 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 4826.56043956 with a balance of 4e-09.
