We look at the division of 850220 by 39 
Let's see how many times 39 fits into 850220.

On to step 1:
39 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 39

Advancing to step 2:
39 can be fit into 85 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 78 from 85 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 39

Moving on to step 3:
39 goes into 70 1 times with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 39 from 70, we get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 39

On to step 4:
312 divided by 39 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 218.0
Subtracting 312 from 312 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 39

Going ahead to step 5:
2 divided by 39 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 2180.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 39

Advancing to step 6:
39 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 21800.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 39 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21800.5
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
39 goes into 50 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 21800.51
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 39 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 21800.512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 39, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 21800.5128
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
39 can be fit into 80 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 21800.51282
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
When dividing 20 by 39, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21800.51282
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
39 goes into 200 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21800.5128205
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 21800.51282051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 21800.51282051 and a remainder of 1.1e-08.
