526621 ÷ 39 
We want to divide 526621 by 39.

Moving on to step 1:
The number 39 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 39

On to step 2:
39 goes into 52 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 52, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 39

Step 3:
The number 39 fits into 136 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 117 from 136 to get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 39

Step 4:
39 can be fit into 196 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
The remainder is 1 after subtracting 195 from 196.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 39

Let's proceed to step 5:
When dividing 12 by 39, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 1350.0
Subtract 0 from 12 to get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 39

On to step 6:
121 divided by 39 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13503.0
Deduct 117 from 121 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
39 goes into 40 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 13503.1
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
10 divided by 39 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13503.1
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
39 goes into 100 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 13503.102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 13503.1025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
When dividing 250 by 39, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 13503.10256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 39 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 13503.102564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 39 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 13503.1025641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
10 divided by 39 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13503.1025641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 13503.1025641 with a remainder of 1e-08.
