We're dividing 8500922 by 399 
We're looking to find how many times 399 goes into 8500922.

Moving on to step 1:
399 goes into 8 0 times with 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.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 399

Let's proceed to step 2:
The number 399 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 399

Let's proceed to step 3:
If we divide 850 by 399, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 798 from 850 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 399

Let's proceed to step 4:
If we divide 520 by 399, we get 1 and a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 399 from 520 leaves us with 121.
Fetch the next digit (9) from the dividend, attach it to 121 and continue: 1219 / 399

Step 5:
The number 399 fits into 1219 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Deduct 1197 from 1219 and we're left with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 399

Advancing to step 6:
When dividing 222 by 399, we get 0 with a remainder of 222.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
Subtracting 0 from 222 leaves us with 222.
Append the next digit (2) from the dividend to 222 and continue with: 2222 / 399

Step 7:
399 can be fit into 2222 5 times, resulting in a remainder of 227.
The number 5 becomes the next digit in our result. 
Result so far: 21305.0
If we subtract 1995 from 2222, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 8:
If we divide 2270 by 399, we get 5 and a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 21305.5
If we take 1995 away from 2270, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 9:
The number 399 fits into 2750 6 times, leaving a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 21305.56
If we take 2394 away from 2750, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
3560 divided by 399 is 8 with a remainder of 368.
The next digit of our result is 8. 
Result so far: 21305.568
Deduct 3192 from 3560 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 11:
If we divide 3680 by 399, we get 9 and a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 21305.5689
The remainder is 89 after subtracting 3591 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 12:
399 can be fit into 890 2 times, resulting in a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 21305.56892
Subtract 798 from 890 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
399 can be fit into 920 2 times, resulting in a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 21305.568922
Subtracting 798 from 920 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 21305.568922, and the remainder is 1.22e-05.
