432398 ÷ 91 
We want to divide 432398 by 91.

Going ahead to step 1:
The number 91 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 91

Step 2:
91 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 91

Moving on to step 3:
If we divide 432 by 91, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 364 from 432 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 91

Step 4:
When dividing 683 by 91, we get 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 637 from 683 to get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 91

Step 5:
The number 91 fits into 469 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 475.0
If we take 455 away from 469, we end up with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 91

Moving on to step 6:
148 divided by 91 is 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 4751.0
Subtracting 91 from 148 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
If we divide 570 by 91, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 4751.6
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
91 can be fit into 240 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 4751.62
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
91 can be fit into 580 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 4751.626
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
91 goes into 340 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 4751.6263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
91 can be fit into 670 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 4751.62637
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
330 divided by 91 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 4751.626373
Deduct 273 from 330 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
91 goes into 570 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4751.6263736
Deduct 546 from 570 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
If we divide 240 by 91, we get 2 and a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4751.62637362
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 4751.62637362 and a remainder of 5.8e-08.
