840991 divided by 39 
Let's see how many times 39 fits into 840991.

Let's proceed to step 1:
39 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 subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 39

Advancing to step 2:
84 divided by 39 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 78 from 84 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 39

Going ahead to step 3:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 21.0
If we take 39 away from 60, we end up with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 39

Going ahead to step 4:
If we divide 219 by 39, we get 5 and a remainder of 24.
The next digit of our result is 5. 
Result so far: 215.0
Subtracting 195 from 219 leaves us with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 39

Going ahead to step 5:
39 can be fit into 249 6 times, resulting in a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 2156.0
The remainder is 15 after subtracting 234 from 249.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 39

On to step 6:
39 goes into 151 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 21563.0
If we subtract 117 from 151, 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.

Going ahead to step 7:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 21563.8
If we take 312 away from 340, we end up 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.

Step 8:
If we divide 280 by 39, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 21563.87
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 39, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 21563.871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
310 divided by 39 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 21563.8717
If we take 273 away from 310, we end up 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.

On to step 11:
When dividing 370 by 39, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 21563.87179
If we take 351 away from 370, we end up with 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 12:
190 divided by 39 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 21563.871794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
If we divide 340 by 39, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 21563.8717948
If we take 312 away from 340, we end up 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.

Step 14:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 21563.87179487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 21563.87179487 with a remaining 7e-09.
