We're dividing 84570715 by 457 
We want to figure out the number of times 84570715 can be divided by 457.

On to step 1:
If we divide 8 by 457, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 457

Step 2:
When dividing 84 by 457, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 457

Advancing to step 3:
457 goes into 845 1 times with a remainder of 388.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 457 from 845 leaves us with 388.
Bring next digit (7) of the dividend behind the 388 and repeat the process: 3887 / 457

Moving on to step 4:
The number 457 fits into 3887 8 times, leaving a remainder of 231.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 3656 from 3887 to get 231.
Bring next digit (0) of the dividend behind the 231 and repeat the process: 2310 / 457

Step 5:
The number 457 fits into 2310 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 185.0
If we subtract 2285 from 2310, we get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 457

Going ahead to step 6:
The number 457 fits into 257 0 times, leaving a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 1850.0
Subtract 0 from 257 to get 257.
Grab the next digit (1) from the dividend, add it to 257, then carry on: 2571 / 457

Going ahead to step 7:
457 can be fit into 2571 5 times, resulting in a remainder of 286.
Record the quotient 5 as the next digit in the result. 
Result so far: 18505.0
Subtract 2285 from 2571 to get 286.
Take the next digit (5) from the dividend and append it to 286, then repeat: 2865 / 457

Step 8:
The number 457 fits into 2865 6 times, leaving a remainder of 123.
Put 6 as the next digit of the answer. 
Result so far: 185056.0
Subtracting 2742 from 2865 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
When dividing 1230 by 457, we get 2 with a remainder of 316.
The next digit of our result is 2. 
Result so far: 185056.2
Deduct 914 from 1230 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
3160 divided by 457 is 6 with a remainder of 418.
Use 6 as the next digit of our solution. 
Result so far: 185056.26
If we take 2742 away from 3160, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 11:
If we divide 4180 by 457, we get 9 and a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 185056.269
The remainder is 67 after subtracting 4113 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
670 divided by 457 is 1 with a remainder of 213.
The number 1 becomes the next digit in our result. 
Result so far: 185056.2691
If we subtract 457 from 670, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 13:
457 goes into 2130 4 times with a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 185056.26914
Subtract 1828 from 2130 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 14:
If we divide 3020 by 457, we get 6 and a remainder of 278.
The number 6 becomes the next digit in our result. 
Result so far: 185056.269146
Subtracting 2742 from 3020 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 15:
457 can be fit into 2780 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 185056.2691466
Deduct 2742 from 2780 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 185056.2691466 with a remainder of 3.8e-07.
