We're dividing 851905 by 39 
Our goal is to divide 851905 by 39.

Going ahead to step 1:
8 divided by 39 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.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 39

Step 2:
If we divide 85 by 39, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 78 from 85, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 39

Advancing to step 3:
When dividing 71 by 39, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 39 from 71 and we're left with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 39

Step 4:
If we divide 329 by 39, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 218.0
Subtract 312 from 329 to get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 39

On to step 5:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 2184.0
If we subtract 156 from 170, we get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 39

On to step 6:
The number 39 fits into 145 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 21843.0
Deduct 117 from 145 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
If we divide 280 by 39, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 21843.7
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 21843.71
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
310 divided by 39 is 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 21843.717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
39 goes into 370 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 21843.7179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
If we divide 190 by 39, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 21843.71794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
If we divide 340 by 39, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 21843.717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 39 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 21843.7179487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
39 can be fit into 70 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 21843.71794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 21843.71794871 with a balance of 3.1e-08.
