430930 ÷ 91 
We want to divide 430930 by 91.

On to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 91

On to step 2:
91 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.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 91

Going ahead to step 3:
91 goes into 430 4 times with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 364 away from 430, we end up with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 91

On to step 4:
The number 91 fits into 669 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 637 from 669, we get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 91

Let's proceed to step 5:
When dividing 323 by 91, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 473.0
Deduct 273 from 323 and we're left with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 91

Advancing to step 6:
500 divided by 91 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 4735.0
Subtracting 455 from 500 leaves us 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.

On to step 7:
450 divided by 91 is 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 4735.4
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.

Advancing to step 8:
860 divided by 91 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 4735.49
The remainder is 41 after subtracting 819 from 860.
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 9:
The number 91 fits into 410 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4735.494
The remainder is 46 after subtracting 364 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
When dividing 460 by 91, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4735.4945
The remainder is 5 after subtracting 455 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
When dividing 50 by 91, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4735.4945
Subtract 0 from 50 to 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.

Moving on to step 12:
When dividing 500 by 91, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4735.494505
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.

Moving on to step 13:
91 can be fit into 450 4 times, resulting in a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 4735.4945054
If we subtract 364 from 450, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 14:
91 can be fit into 860 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 4735.49450549
Subtracting 819 from 860 leaves us 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.

After the division, we end up with 4735.49450549 and a remainder of 4.1e-08.
