85104097 ÷ 458 
We want to figure out the number of times 85104097 can be divided by 458.

On to step 1:
The number 458 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 458

Going ahead to step 2:
When dividing 85 by 458, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 458

Moving on to step 3:
458 goes into 851 1 times with a remainder of 393.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 393 after subtracting 458 from 851.
Grab the next digit (0) from the dividend, add it to 393, then carry on: 3930 / 458

Let's proceed to step 4:
458 can be fit into 3930 8 times, resulting in a remainder of 266.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 266 after subtracting 3664 from 3930.
Include the next digit (4) from the dividend after 266, then repeat: 2664 / 458

Let's proceed to step 5:
2664 divided by 458 is 5 with a remainder of 374.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
The remainder is 374 after subtracting 2290 from 2664.
Append the next digit (0) from the dividend to 374 and continue with: 3740 / 458

Advancing to step 6:
3740 divided by 458 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 1858.0
The remainder is 76 after subtracting 3664 from 3740.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 458

On to step 7:
769 divided by 458 is 1 with a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 18581.0
If we take 458 away from 769, we end up with 311.
Bring next digit (7) of the dividend behind the 311 and repeat the process: 3117 / 458

Going ahead to step 8:
458 can be fit into 3117 6 times, resulting in a remainder of 369.
Use 6 as the next digit of our solution. 
Result so far: 185816.0
If we take 2748 away from 3117, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 9:
458 goes into 3690 8 times with a remainder of 26.
The next digit of our result is 8. 
Result so far: 185816.8
Deduct 3664 from 3690 and we're left with 26.
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 10:
If we divide 260 by 458, we get 0 and a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 185816.8
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
458 can be fit into 2600 5 times, resulting in a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 185816.805
Deduct 2290 from 2600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
If we divide 3100 by 458, we get 6 and a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 185816.8056
Deduct 2748 from 3100 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
458 can be fit into 3520 7 times, resulting in a remainder of 314.
The number 7 becomes the next digit in our result. 
Result so far: 185816.80567
Subtract 3206 from 3520 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 14:
3140 divided by 458 is 6 with a remainder of 392.
The next digit of our result is 6. 
Result so far: 185816.805676
The remainder is 392 after subtracting 2748 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 15:
When dividing 3920 by 458, we get 8 with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 185816.8056768
Subtract 3664 from 3920 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 16:
2560 divided by 458 is 5 with a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 185816.80567685
If we take 2290 away from 2560, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

After the division, we end up with 185816.80567685 and a remainder of 2.7e-07.
