We're dividing 28430514 by 91 
We want to figure out the number of times 28430514 can be divided by 91.

On to step 1:
If we divide 2 by 91, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 91

Let's proceed to step 2:
91 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 91

Let's proceed to step 3:
When dividing 284 by 91, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 11 after subtracting 273 from 284.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 91

Going ahead to step 4:
91 can be fit into 113 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 91 away from 113, we end up with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 91

Step 5:
When dividing 220 by 91, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 312.0
Deduct 182 from 220 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 91

Advancing to step 6:
When dividing 385 by 91, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 3124.0
If we take 364 away from 385, we end up with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 91

Advancing to step 7:
If we divide 211 by 91, we get 2 and a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 31242.0
If we subtract 182 from 211, we get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 91

Going ahead to step 8:
The number 91 fits into 294 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 312423.0
Deduct 273 from 294 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
91 goes into 210 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 312423.2
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
When dividing 280 by 91, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 312423.23
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
When dividing 70 by 91, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 312423.23
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
91 goes into 700 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 312423.2307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 13:
91 can be fit into 630 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 312423.23076
Subtracting 546 from 630 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 14:
If we divide 840 by 91, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 312423.230769
Subtracting 819 from 840 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 15:
If we divide 210 by 91, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 312423.2307692
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
The number 91 fits into 280 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 312423.23076923
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 312423.23076923, and the remainder is 7e-09.
