84784134 ÷ 664 
We want to figure out the number of times 84784134 can be divided by 664.

Advancing to step 1:
The number 664 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 664

Moving on to step 2:
If we divide 84 by 664, we get 0 and a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 664

Step 3:
664 can be fit into 847 1 times, resulting in a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 664 from 847 to get 183.
Append the next digit (8) from the dividend to 183 and continue with: 1838 / 664

Step 4:
The number 664 fits into 1838 2 times, leaving a remainder of 510.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1328 from 1838 and we're left with 510.
Append the next digit (4) from the dividend to 510 and continue with: 5104 / 664

Moving on to step 5:
When dividing 5104 by 664, we get 7 with a remainder of 456.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Deduct 4648 from 5104 and we're left with 456.
Include the next digit (1) from the dividend after 456, then repeat: 4561 / 664

Advancing to step 6:
When dividing 4561 by 664, we get 6 with a remainder of 577.
Write down 6 as next digit of the result. 
Result so far: 1276.0
If we subtract 3984 from 4561, we get 577.
Include the next digit (3) from the dividend after 577, then repeat: 5773 / 664

Moving on to step 7:
When dividing 5773 by 664, we get 8 with a remainder of 461.
The number 8 becomes the next digit in our result. 
Result so far: 12768.0
Subtract 5312 from 5773 to get 461.
Include the next digit (4) from the dividend after 461, then repeat: 4614 / 664

Advancing to step 8:
If we divide 4614 by 664, we get 6 and a remainder of 630.
Record the quotient 6 as the next digit in the result. 
Result so far: 127686.0
If we take 3984 away from 4614, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 9:
664 can be fit into 6300 9 times, resulting in a remainder of 324.
Record the quotient 9 as the next digit in the result. 
Result so far: 127686.9
If we take 5976 away from 6300, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
The number 664 fits into 3240 4 times, leaving a remainder of 584.
The next digit of our result is 4. 
Result so far: 127686.94
Subtract 2656 from 3240 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 11:
664 goes into 5840 8 times with a remainder of 528.
The next digit of our result is 8. 
Result so far: 127686.948
If we subtract 5312 from 5840, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 12:
5280 divided by 664 is 7 with a remainder of 632.
The next digit of our result is 7. 
Result so far: 127686.9487
Subtract 4648 from 5280 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 13:
The number 664 fits into 6320 9 times, leaving a remainder of 344.
Use 9 as the next digit of our solution. 
Result so far: 127686.94879
Subtract 5976 from 6320 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 14:
664 can be fit into 3440 5 times, resulting in a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 127686.948795
Subtract 3320 from 3440 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
The number 664 fits into 1200 1 times, leaving a remainder of 536.
Use 1 as the next digit of our solution. 
Result so far: 127686.9487951
Subtracting 664 from 1200 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 16:
664 can be fit into 5360 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 127686.94879518
Subtract 5312 from 5360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 127686.94879518, with a leftover of 4.8e-08.
