We're dividing 406329 by 91 
We want to figure out the number of times 406329 can be divided by 91.

Step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 91

Advancing to step 2:
If we divide 40 by 91, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 91

Let's proceed to step 3:
The number 91 fits into 406 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 364 from 406, we get 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 91

Step 4:
423 divided by 91 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 44.0
If we take 364 away from 423, we end up with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 91

Moving on to step 5:
The number 91 fits into 592 6 times, leaving a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 446.0
The remainder is 46 after subtracting 546 from 592.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 91

Moving on to step 6:
The number 91 fits into 469 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 4465.0
If we subtract 455 from 469, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4465.1
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 8:
The number 91 fits into 490 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 4465.15
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 91 fits into 350 3 times, leaving a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 4465.153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
When dividing 770 by 91, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 4465.1538
Deduct 728 from 770 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 91 fits into 420 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4465.15384
Subtract 364 from 420 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
When dividing 560 by 91, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 4465.153846
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
91 goes into 140 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 4465.1538461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
490 divided by 91 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4465.15384615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 4465.15384615 and a remainder of 3.5e-08.
