We look at the division of 33165166 by 391 
Our goal is to divide 33165166 by 391.

On to step 1:
If we divide 3 by 391, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 391

Step 2:
If we divide 33 by 391, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 391

Going ahead to step 3:
391 can be fit into 331 0 times, resulting in a remainder of 331.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 331 after subtracting 0 from 331.
Take the next digit (6) from the dividend and append it to 331, then repeat: 3316 / 391

Moving on to step 4:
3316 divided by 391 is 8 with a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 3128 from 3316 leaves us with 188.
Bring next digit (5) of the dividend behind the 188 and repeat the process: 1885 / 391

Advancing to step 5:
391 can be fit into 1885 4 times, resulting in a remainder of 321.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 1564 from 1885 leaves us with 321.
Bring next digit (1) of the dividend behind the 321 and repeat the process: 3211 / 391

Step 6:
391 goes into 3211 8 times with a remainder of 83.
The next digit of our result is 8. 
Result so far: 848.0
Subtracting 3128 from 3211 leaves us with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 391

Step 7:
391 can be fit into 836 2 times, resulting in a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 8482.0
Subtracting 782 from 836 leaves us with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 391

Moving on to step 8:
If we divide 546 by 391, we get 1 and a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 84821.0
Deduct 391 from 546 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 9:
If we divide 1550 by 391, we get 3 and a remainder of 377.
Record the quotient 3 as the next digit in the result. 
Result so far: 84821.3
If we take 1173 away from 1550, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 10:
3770 divided by 391 is 9 with a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 84821.39
Subtract 3519 from 3770 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 11:
The number 391 fits into 2510 6 times, leaving a remainder of 164.
The next digit of our result is 6. 
Result so far: 84821.396
If we subtract 2346 from 2510, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
If we divide 1640 by 391, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 84821.3964
If we subtract 1564 from 1640, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
760 divided by 391 is 1 with a remainder of 369.
Record the quotient 1 as the next digit in the result. 
Result so far: 84821.39641
Subtract 391 from 760 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 14:
391 can be fit into 3690 9 times, resulting in a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 84821.396419
Subtracting 3519 from 3690 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 15:
If we divide 1710 by 391, we get 4 and a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 84821.3964194
If we subtract 1564 from 1710, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 16:
The number 391 fits into 1460 3 times, leaving a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 84821.39641943
If we take 1173 away from 1460, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

In conclusion, the division gives 84821.39641943 with a balance of 2.87e-07.
