We're dividing 491575 by 39 
We want to figure out the number of times 491575 can be divided by 39.

Let's proceed to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 39

Advancing to step 2:
The number 39 fits into 49 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 39 from 49 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 39

Moving on to step 3:
39 goes into 101 2 times with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 78 from 101 and we're left with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 39

Let's proceed to step 4:
The number 39 fits into 235 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 234 away from 235, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 39

Let's proceed to step 5:
39 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 1260.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 39

Advancing to step 6:
39 can be fit into 175 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 12604.0
If we take 156 away from 175, we end up 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.

Advancing to step 7:
When dividing 190 by 39, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 12604.4
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 12604.48
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 12604.487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
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: 12604.4871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
310 divided by 39 is 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 12604.48717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
39 goes into 370 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 12604.487179
Subtract 351 from 370 to 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.

On to step 13:
39 goes into 190 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 12604.4871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
When dividing 340 by 39, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 12604.48717948
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 12604.48717948, with a leftover of 2.8e-08.
