Let's divide 434430 by 91
We're looking to find how many times 91 goes into 434430.

On to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 91

Step 2:
If we divide 43 by 91, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 91

Advancing to step 3:
91 can be fit into 434 4 times, resulting in a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 364 from 434 to get 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 91

Moving on to step 4:
704 divided by 91 is 7 with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 637 away from 704, we end up with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 91

On to step 5:
If we divide 673 by 91, we get 7 and a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
Subtracting 637 from 673 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 91

Moving on to step 6:
91 can be fit into 360 3 times, resulting in a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 4773.0
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 7:
The number 91 fits into 870 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 4773.9
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
If we divide 510 by 91, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4773.95
If we take 455 away from 510, we end up 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.

Step 9:
550 divided by 91 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4773.956
If we subtract 546 from 550, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 91, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4773.956
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.

Going ahead to step 11:
91 goes into 400 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 4773.95604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 4773.956043
The remainder is 87 after subtracting 273 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
When dividing 870 by 91, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 4773.9560439
If we take 819 away from 870, we end up 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.

Advancing to step 14:
510 divided by 91 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4773.95604395
Subtract 455 from 510 to 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.

The quotient of the division is 4773.95604395, and the remainder is 5.5e-08.
