We're dividing 783564 by 39 
We want to divide 783564 by 39.

Advancing to step 1:
7 divided by 39 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 39

Let's proceed to step 2:
39 can be fit into 78 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 78 from 78 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 39

Let's proceed to step 3:
If we divide 3 by 39, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 39

Going ahead to step 4:
35 divided by 39 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 200.0
If we take 0 away from 35, we end up with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 39

Step 5:
If we divide 356 by 39, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 2009.0
Deduct 351 from 356 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 39

Step 6:
39 can be fit into 54 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 20091.0
Subtracting 39 from 54 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.

Step 7:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 20091.3
If we take 117 away from 150, we end up 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.

On to step 8:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 20091.38
Subtract 312 from 330 to 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.

Advancing to step 9:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 20091.384
Deduct 156 from 180 and we're left 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.

Advancing to step 10:
39 goes into 240 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 20091.3846
Deduct 234 from 240 and we're left 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.

Let's proceed to step 11:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 20091.38461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
39 goes into 210 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 20091.384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 20091.3846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 20091.38461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 20091.38461538, with a leftover of 1.8e-08.
