84853989 ÷ 666 
Let's see how many times 666 fits into 84853989.

Going ahead to step 1:
If we divide 8 by 666, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 666

Step 2:
If we divide 84 by 666, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 666

On to step 3:
666 can be fit into 848 1 times, resulting in a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 666 from 848 leaves us with 182.
Take the next digit (5) from the dividend and append it to 182, then repeat: 1825 / 666

Going ahead to step 4:
The number 666 fits into 1825 2 times, leaving a remainder of 493.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1332 from 1825, we get 493.
Grab the next digit (3) from the dividend, add it to 493, then carry on: 4933 / 666

Advancing to step 5:
The number 666 fits into 4933 7 times, leaving a remainder of 271.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 4662 from 4933 and we're left with 271.
Take the next digit (9) from the dividend and append it to 271, then repeat: 2719 / 666

Let's proceed to step 6:
If we divide 2719 by 666, we get 4 and a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 1274.0
Deduct 2664 from 2719 and we're left with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 666

Going ahead to step 7:
558 divided by 666 is 0 with a remainder of 558.
Record the quotient 0 as the next digit in the result. 
Result so far: 12740.0
If we subtract 0 from 558, we get 558.
Bring next digit (9) of the dividend behind the 558 and repeat the process: 5589 / 666

Moving on to step 8:
666 can be fit into 5589 8 times, resulting in a remainder of 261.
Use 8 as the next digit of our solution. 
Result so far: 127408.0
The remainder is 261 after subtracting 5328 from 5589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 9:
The number 666 fits into 2610 3 times, leaving a remainder of 612.
Write down 3 as next digit of the result. 
Result so far: 127408.3
The remainder is 612 after subtracting 1998 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 10:
If we divide 6120 by 666, we get 9 and a remainder of 126.
The next digit of our result is 9. 
Result so far: 127408.39
If we take 5994 away from 6120, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 11:
1260 divided by 666 is 1 with a remainder of 594.
Use 1 as the next digit of our solution. 
Result so far: 127408.391
If we subtract 666 from 1260, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 12:
666 can be fit into 5940 8 times, resulting in a remainder of 612.
The next digit of our result is 8. 
Result so far: 127408.3918
Subtracting 5328 from 5940 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 13:
666 goes into 6120 9 times with a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 127408.39189
Deduct 5994 from 6120 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 14:
666 goes into 1260 1 times with a remainder of 594.
Record the quotient 1 as the next digit in the result. 
Result so far: 127408.391891
Subtract 666 from 1260 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 15:
The number 666 fits into 5940 8 times, leaving a remainder of 612.
The next digit of our result is 8. 
Result so far: 127408.3918918
Deduct 5328 from 5940 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 16:
If we divide 6120 by 666, we get 9 and a remainder of 126.
Put 9 as the next digit of the answer. 
Result so far: 127408.39189189
If we subtract 5994 from 6120, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Our division results in 127408.39189189 with a remaining 1.26e-07.
