91280509 ÷ 463 
We want to figure out the number of times 91280509 can be divided by 463.

On to step 1:
If we divide 9 by 463, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 463

Let's proceed to step 2:
91 divided by 463 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 463

Advancing to step 3:
463 can be fit into 912 1 times, resulting in a remainder of 449.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 449 after subtracting 463 from 912.
Take the next digit (8) from the dividend and append it to 449, then repeat: 4498 / 463

On to step 4:
When dividing 4498 by 463, we get 9 with a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 4167 from 4498 and we're left with 331.
Include the next digit (0) from the dividend after 331, then repeat: 3310 / 463

Going ahead to step 5:
463 can be fit into 3310 7 times, resulting in a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we take 3241 away from 3310, we end up with 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 463

Step 6:
The number 463 fits into 695 1 times, leaving a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 1971.0
Subtract 463 from 695 to get 232.
Take the next digit (0) from the dividend and append it to 232, then repeat: 2320 / 463

Going ahead to step 7:
463 goes into 2320 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 19715.0
The remainder is 5 after subtracting 2315 from 2320.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 463

Moving on to step 8:
59 divided by 463 is 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 197150.0
Deduct 0 from 59 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
463 goes into 590 1 times with a remainder of 127.
Record the quotient 1 as the next digit in the result. 
Result so far: 197150.1
Deduct 463 from 590 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 10:
463 can be fit into 1270 2 times, resulting in a remainder of 344.
The next digit of our result is 2. 
Result so far: 197150.12
Deduct 926 from 1270 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
The number 463 fits into 3440 7 times, leaving a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 197150.127
The remainder is 199 after subtracting 3241 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 12:
463 goes into 1990 4 times with a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 197150.1274
If we subtract 1852 from 1990, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 13:
1380 divided by 463 is 2 with a remainder of 454.
The next digit of our result is 2. 
Result so far: 197150.12742
If we subtract 926 from 1380, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 14:
When dividing 4540 by 463, we get 9 with a remainder of 373.
Put 9 as the next digit of the answer. 
Result so far: 197150.127429
Subtract 4167 from 4540 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 15:
If we divide 3730 by 463, we get 8 and a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 197150.1274298
The remainder is 26 after subtracting 3704 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
463 can be fit into 260 0 times, resulting in a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 197150.1274298
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 197150.1274298, with a leftover of 2.6e-07.
