843490 divided by 39 
Let's see how many times 39 fits into 843490.

Moving on to step 1:
8 divided by 39 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 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
Subtract 78 from 84 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 39

Advancing to step 3:
39 can be fit into 63 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 24 after subtracting 39 from 63.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 39

Step 4:
39 goes into 244 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtracting 234 from 244 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 39

Moving on to step 5:
39 can be fit into 109 2 times, resulting in a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2162.0
The remainder is 31 after subtracting 78 from 109.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 39

Moving on to step 6:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 21627.0
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.

Advancing to step 7:
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: 21627.9
If we subtract 351 from 370, we 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 8:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 21627.94
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
39 goes into 340 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 21627.948
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.

Going ahead to step 10:
280 divided by 39 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 21627.9487
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.

On to step 11:
When dividing 70 by 39, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 21627.94871
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.

On to step 12:
310 divided by 39 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 21627.948717
Subtracting 273 from 310 leaves us 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.

Let's proceed to step 13:
If we divide 370 by 39, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 21627.9487179
Subtracting 351 from 370 leaves us 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.

Moving on to step 14:
If we divide 190 by 39, we get 4 and a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 21627.94871794
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.

The final result is 21627.94871794 with a remainder of 3.4e-08.
