Let's divide 435485 by 91
We're looking to find how many times 91 goes into 435485.

On to step 1:
91 goes into 4 0 times 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.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 91

Going ahead to step 2:
The number 91 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 91

Advancing to step 3:
If we divide 435 by 91, we get 4 and a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 364 from 435 and we're left with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 91

Going ahead to step 4:
714 divided by 91 is 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 47.0
Subtract 637 from 714 to get 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 91

Advancing to step 5:
91 can be fit into 778 8 times, resulting in a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 478.0
Deduct 728 from 778 and we're left with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 91

Moving on to step 6:
The number 91 fits into 505 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4785.0
If we subtract 455 from 505, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
91 can be fit into 500 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 4785.5
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
The number 91 fits into 450 4 times, leaving a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 4785.54
The remainder is 86 after subtracting 364 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
When dividing 860 by 91, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 4785.549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
410 divided by 91 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 4785.5494
Subtracting 364 from 410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
When dividing 460 by 91, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4785.54945
If we take 455 away from 460, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 91 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4785.54945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
91 goes into 500 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 4785.5494505
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
The number 91 fits into 450 4 times, leaving a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 4785.54945054
Subtracting 364 from 450 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 4785.54945054 with a balance of 8.6e-08.
