991002 divided by 457 
Our goal is to divide 991002 by 457.

Going ahead to step 1:
457 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 457

Going ahead to step 2:
The number 457 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (1) of the dividend behind the 99 and repeat the process: 991 / 457

On to step 3:
The number 457 fits into 991 2 times, leaving a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 914 from 991 to get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 457

Advancing to step 4:
When dividing 770 by 457, we get 1 with a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 457 from 770 to get 313.
Fetch the next digit (0) from the dividend, attach it to 313 and continue: 3130 / 457

Moving on to step 5:
When dividing 3130 by 457, we get 6 with a remainder of 388.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Subtracting 2742 from 3130 leaves us with 388.
Take the next digit (2) from the dividend and append it to 388, then repeat: 3882 / 457

Step 6:
3882 divided by 457 is 8 with a remainder of 226.
Record the quotient 8 as the next digit in the result. 
Result so far: 2168.0
Subtract 3656 from 3882 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 7:
The number 457 fits into 2260 4 times, leaving a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 2168.4
Deduct 1828 from 2260 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 8:
The number 457 fits into 4320 9 times, leaving a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 2168.49
The remainder is 207 after subtracting 4113 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 9:
If we divide 2070 by 457, we get 4 and a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 2168.494
If we subtract 1828 from 2070, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 10:
457 can be fit into 2420 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 2168.4945
The remainder is 135 after subtracting 2285 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
The number 457 fits into 1350 2 times, leaving a remainder of 436.
Record the quotient 2 as the next digit in the result. 
Result so far: 2168.49452
Subtract 914 from 1350 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 12:
When dividing 4360 by 457, we get 9 with a remainder of 247.
Use 9 as the next digit of our solution. 
Result so far: 2168.494529
If we take 4113 away from 4360, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 13:
The number 457 fits into 2470 5 times, leaving a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 2168.4945295
Subtract 2285 from 2470 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 14:
When dividing 1850 by 457, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 2168.49452954
Deduct 1828 from 1850 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 2168.49452954 with a balance of 2.2e-08.
