Let's divide 81665778 by 857
We're looking to find how many times 857 goes into 81665778.

Let's proceed to step 1:
8 divided by 857 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 857

Step 2:
857 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 857

Step 3:
857 can be fit into 816 0 times, resulting in a remainder of 816.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 816, we end up with 816.
Take the next digit (6) from the dividend and append it to 816, then repeat: 8166 / 857

Moving on to step 4:
If we divide 8166 by 857, we get 9 and a remainder of 453.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7713 away from 8166, we end up with 453.
Grab the next digit (5) from the dividend, add it to 453, then carry on: 4535 / 857

Let's proceed to step 5:
857 goes into 4535 5 times with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we take 4285 away from 4535, we end up with 250.
Include the next digit (7) from the dividend after 250, then repeat: 2507 / 857

On to step 6:
857 can be fit into 2507 2 times, resulting in a remainder of 793.
The number 2 becomes the next digit in our result. 
Result so far: 952.0
Deduct 1714 from 2507 and we're left with 793.
Bring next digit (7) of the dividend behind the 793 and repeat the process: 7937 / 857

Advancing to step 7:
857 goes into 7937 9 times with a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 9529.0
Deduct 7713 from 7937 and we're left with 224.
Bring next digit (8) of the dividend behind the 224 and repeat the process: 2248 / 857

Moving on to step 8:
857 can be fit into 2248 2 times, resulting in a remainder of 534.
Use 2 as the next digit of our solution. 
Result so far: 95292.0
If we take 1714 away from 2248, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 9:
5340 divided by 857 is 6 with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 95292.6
Subtract 5142 from 5340 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
If we divide 1980 by 857, we get 2 and a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 95292.62
Subtracting 1714 from 1980 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 11:
If we divide 2660 by 857, we get 3 and a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 95292.623
The remainder is 89 after subtracting 2571 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
If we divide 890 by 857, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 95292.6231
Subtracting 857 from 890 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
857 goes into 330 0 times with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 95292.6231
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
3300 divided by 857 is 3 with a remainder of 729.
Record the quotient 3 as the next digit in the result. 
Result so far: 95292.623103
If we take 2571 away from 3300, we end up with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Let's proceed to step 15:
857 can be fit into 7290 8 times, resulting in a remainder of 434.
Put 8 as the next digit of the answer. 
Result so far: 95292.6231038
If we subtract 6856 from 7290, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 16:
When dividing 4340 by 857, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 95292.62310385
Subtracting 4285 from 4340 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 95292.62310385 and a remainder of 5.5e-08.
