We look at the division of 819983 by 39 
We want to figure out the number of times 819983 can be divided by 39.

On 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
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 39

Moving on to step 2:
81 divided by 39 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 78 from 81, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 39

Going ahead to step 3:
The number 39 fits into 39 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 0 after subtracting 39 from 39.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 39

Moving on to step 4:
When dividing 9 by 39, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 39

Let's proceed to step 5:
The number 39 fits into 98 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2102.0
The remainder is 20 after subtracting 78 from 98.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 39

Step 6:
39 can be fit into 203 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 21025.0
The remainder is 8 after subtracting 195 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
39 goes into 80 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 21025.2
If we subtract 78 from 80, we 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.

Advancing to step 8:
20 divided by 39 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 21025.2
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
39 goes into 200 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21025.205
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.

Let's proceed to step 10:
If we divide 50 by 39, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 21025.2051
Deduct 39 from 50 and we're left 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.

Advancing to step 11:
When dividing 110 by 39, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 21025.20512
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
39 can be fit into 320 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 21025.205128
If we take 312 away from 320, we end up 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.

On to step 13:
39 goes into 80 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 21025.2051282
If we take 78 away from 80, we end up with 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 14:
When dividing 20 by 39, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21025.2051282
If we subtract 0 from 20, we 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.

In conclusion, the division gives 21025.2051282 with a balance of 2e-08.
