We divide 789639 by 39
We want to figure out the number of times 789639 can be divided by 39.

Let's proceed to step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 39

Step 2:
39 goes into 78 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 78 from 78 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 39

Advancing to step 3:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 9, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 39

Step 4:
The number 39 fits into 96 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
If we subtract 78 from 96, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 39

Let's proceed to step 5:
183 divided by 39 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 2024.0
Deduct 156 from 183 and we're left with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 39

Step 6:
If we divide 279 by 39, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 20247.0
If we take 273 away from 279, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 39 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 20247.1
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
39 goes into 210 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 20247.15
Subtracting 195 from 210 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 39 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 20247.153
Subtracting 117 from 150 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
If we divide 330 by 39, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 20247.1538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 20247.15384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 39 fits into 240 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 20247.153846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 20247.1538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 20247.15384615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 20247.15384615, with a leftover of 1.5e-08.
