Let's divide 55566309 by 850
Let's see how many times 850 fits into 55566309.

Advancing to step 1:
When dividing 5 by 850, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 850

Moving on to step 2:
When dividing 55 by 850, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 850

Going ahead to step 3:
The number 850 fits into 555 0 times, leaving a remainder of 555.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 555 after subtracting 0 from 555.
Bring next digit (6) of the dividend behind the 555 and repeat the process: 5556 / 850

On to step 4:
When dividing 5556 by 850, we get 6 with a remainder of 456.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5100 from 5556 and we're left with 456.
Append the next digit (6) from the dividend to 456 and continue with: 4566 / 850

Moving on to step 5:
850 goes into 4566 5 times with a remainder of 316.
The next digit of our result is 5. 
Result so far: 65.0
If we take 4250 away from 4566, we end up with 316.
Take the next digit (3) from the dividend and append it to 316, then repeat: 3163 / 850

On to step 6:
3163 divided by 850 is 3 with a remainder of 613.
The number 3 becomes the next digit in our result. 
Result so far: 653.0
Subtracting 2550 from 3163 leaves us with 613.
Include the next digit (0) from the dividend after 613, then repeat: 6130 / 850

Moving on to step 7:
If we divide 6130 by 850, we get 7 and a remainder of 180.
The next digit of our result is 7. 
Result so far: 6537.0
Subtract 5950 from 6130 to get 180.
Include the next digit (9) from the dividend after 180, then repeat: 1809 / 850

On to step 8:
850 goes into 1809 2 times with a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 65372.0
Subtracting 1700 from 1809 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 9:
The number 850 fits into 1090 1 times, leaving a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 65372.1
Deduct 850 from 1090 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
2400 divided by 850 is 2 with a remainder of 700.
Record the quotient 2 as the next digit in the result. 
Result so far: 65372.12
Subtracting 1700 from 2400 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
If we divide 7000 by 850, we get 8 and a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 65372.128
The remainder is 200 after subtracting 6800 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 850 fits into 2000 2 times, leaving a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 65372.1282
Subtracting 1700 from 2000 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
3000 divided by 850 is 3 with a remainder of 450.
Put 3 as the next digit of the answer. 
Result so far: 65372.12823
If we subtract 2550 from 3000, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
4500 divided by 850 is 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 65372.128235
If we subtract 4250 from 4500, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 15:
If we divide 2500 by 850, we get 2 and a remainder of 800.
Use 2 as the next digit of our solution. 
Result so far: 65372.1282352
Deduct 1700 from 2500 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 16:
850 can be fit into 8000 9 times, resulting in a remainder of 350.
Write down 9 as next digit of the result. 
Result so far: 65372.12823529
If we take 7650 away from 8000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 65372.12823529 and a remainder of 3.5e-07.
